Cats up for adoption in Orange County, CA

Are you looking for a cute cat or kitten to adopt in Costa Mesa, California?  Here’s a list of some of the cats currently available for adoption through Miss Kitty’s Rescue:

[Note: Click each cat’s image or name to see more information about the cat.]

Zoey, a less than year old short-haired white and black bicolor female cat with yellow green eyes up for adoption at Miss Kitty's Rescue in Costa Mesa, CA, is held by Mindy, owner of Miss Kitty's Rescue.  Zoey is sisters with Porsche, and the two need to be adopted together as a pair.  Zoey has a little bit of lipstick on her face, thanks to a recent "kiss" from Mindy.  Zoey has a nipped left ear, a sign that she may have been captured in a catch-and-release spay program for feral cats.  This picture was taken pro bono for Miss Kitty's Rescue to help them advertise the cats for adoption. (Marc C. Perkins) Porsche, a less than year old short-haired white and black bicolor female cat with yellow green eyes up for adoption at Miss Kitty's Rescue in Costa Mesa, CA, is held by Mindy, owner of Miss Kitty's Rescue.  Porsche is sisters with Zoey (seen in other pictures), and the two need to be adopted together as a pair.  She has a cute black spot on her pink nose, and is probably a mask-and-mantle pattern. Porsche has a nipped left ear, a sign that she may have been captured in a catch-and-release spay program for feral cats.  This picture was taken pro bono for Miss Kitty's Rescue to help them advertise the cats for adoption. (Marc C. Perkins)

Hurricane, a seven year old male short-haired black cat, staring into the camera for a portrait.  Hurricane is a very intelligent, outgoing cat who loves people and is not afraid of anything, but who needs to live in a house without other pets as he can be aggressive to other dogs and cats.  Hurricane is up for adoption at Miss Kitty's Rescue in Costa Mesa, CA.  This picture was taken pro bono for Miss Kitty's Rescue to help them advertise the cats for adoption. (Marc C. Perkins)
Hurricane

Trista, a three year old female short-haired brown tabby cat with green eyes (and a white chin), playing with a feather toy from behind a sisal-wrapped cat tree post.   Trista has a face that looks somewhat like a mountain lion to me; a bit more elongated than your typical domesticated cat.  Trista is up for adoption at Miss Kitty's Rescue in Costa Mesa, CA.  This picture was taken pro bono for Miss Kitty's Rescue to help them advertise the cats for adoption. (Marc C. Perkins)

If you’re interested in adopting any of these cats, please contact Mindy of Miss Kitty’s Rescue at misskittysrescue@yahoo.com.  Some of these cats may also be available to be seen at the Petsmart at 620 West 17th St in Costa Mesa, CA 92627.

Kitties who have found a home

These cats have been adopted into a loving home:

Oliver, a two year old male short-haired brown tabby and white cat, looks peacefully just off camera.  Oliver is a sweet cat who needs a home with no dogs and no kids.  Oliver is up for adoption at Miss Kitty's Rescue in Costa Mesa, CA.  This picture was taken pro bono for Miss Kitty's Rescue to help them advertise the cats for adoption. (Marc C. Perkins)
Oliver

Molly, a two year old bicolor tuxedo white and black short-haired cat, looks at her cage door.  Molly is a very playful and fun loving cat who loves to ride on people's shoulders and interact with dogs; she would not be good with small children.  Molly is up for adoption at Miss Kitty's Rescue in Costa Mesa, CA.  This picture was taken pro bono for Miss Kitty's Rescue to help them advertise the cats for adoption. (Marc C. Perkins)

About Miss Kitty’s Rescue

Miss Kitty’s Rescue is a cat rescue group run by Mindy Miller in Costa Mesa, California.  Michelle and I adopted our two cats from Mindy; they were both former feral cats that Mindy tamed herself, and she turned the two of them from fearful, nearly wild cats into two kitties who love spending time with us.

As with most cat rescues, however, Mindy’s rescue is constantly full, and she has trouble finding people to adopt her rescued cats, especially since many of the cats need special homes. To help her out I’ve volunteered to take pictures of her cats pro bono, so she can use them in her own advertising.  She has also asked me to do whatever advertising I can for the cats, and thus I’ve created this post, which will link to all the cats.

More kitties?

To see more cat pictures I’ve taken, you can see a list of all of my pet posts, or head straight to my pets portfolio page.

Pet Posts: One page to organize them all

I write a lot of blog posts about pets. Most of them focus on my own two cats in one way or another, but I also do volunteer work for local animal groups. In this post I’ll maintain a list of my pet-related posts.

Support a good cause, if you so desire

This is a crop of the "Cat tongue closeup: 3/4 view" image, focusing on the tongue.  The original image is a closeup of a cat's tongue from a three-quarters angle as the cat licks a sheepskin rug.  Numerous barbs (spines; filiform papillae) are clearly visible across the width of the tongue.  The papillae are largest in the middle of the tongue, and get progressive smaller towards the edges of the tongue.  The three-quarters angle allows the viewer to better see the height of the barbs.  See the uncropped version of this image for more context. (Marc C. Perkins)
Cat anatomy: the barbed tongue

A closeup of Lucca's hind paw, with her beautiful green eye and nose staring at you from the background in soft focus.  Her paw pad leathers are multicolored because she's a dilute caliby (blue patched tabby and white), so the leathers are patterned just like the rest of her is.  The leathers are a mix of two colors: blue (dilute black) and pink/rose.  The texturing on the pads is also visible; it's like she's got all-terrain tire treads on her paws :) (Marc C. Perkins)

Lucca shows off her third eyelid in this sequence of four photographs taken just after she woke up from a nap.  The third eyelid (nictitating membrane or palpebra tertia) is a thin white membrane that slides horizontally across the eye underneath the outer two eyelids.  Humans lack this third eyelid, but most other vertebrates have it.  Lucca here is simultaneously stretching, yawning, and opening her eyes.  In the first image her eyes are completely closed, in the second image her outer two eyelids are partially open, but the nictitating membrane is still entirely covering the eye, in the third image the outer two eyelids are almost entirely open and the nictitating membrane is about half covering the eye, and in the fourth image all three eyelids are fully open. (Marc C. Perkins)

Lucca looking decidedly unimpressed.  This picture reminds me of a typical LOLCat image (e.g., http://icanhascheezburger.com); I think the caption would be something like "Unimpressed cat is unimpressed", "Meh", or "Is it really Monday already?".  But, sadly, I won't be submitting it to that website, as their terms of service for uploaded images give them way too many rights for free (http://corp.cheezburger.com/legal/terms-of-service/).

Cats (and other pets) up for adoption

Oliver, a two year old male short-haired brown tabby and white cat, sniffs the corner of a cat cage at a rescue shelter.  Oliver likes to climb on top of the cages and explore who is in each one.  Oliver is a sweet cat who needs a home with no dogs and no kids.  Oliver is up for adoption at Miss Kitty's Rescue in Costa Mesa, CA.

Mice

A gray male pet mouse jumps up on the side of a clear plastic cage and holds himself up by his front paws, peering over the edge into the vast unknown beyond the cage.  I love the cute little paws holding onto the edge.  I also like how the whiskers are fully three-dimensional: you can see how they extend around the face in all directions - front, back, top, bottom, and sides. (Marc C. Perkins)

Old Point Loma Lighthouse pictures

After taking pictures of pelicans at La Jolla this past January, Greg and I headed down to Cabrillo National Monument in San Diego to get pictures of Old Point Loma Lighthouse. I probably shouldn’t admit this, but the lighthouse was what I was really looking forward to when I woke up that day; birds and sunrises are fun and all, but I have a mild obsession with lighthouses1.

Old Point Loma Lighthouse stands on the top of a hill at the end of Point Loma, one of the peninsulas that shelter San Diego’s natural harbor.

Old Point Loma Light standing proud, seen end-on from the south on a sunny winter day.  The light is in Cabrillo National Monument near San Diego, CA.  Framing the lighthouse are three withered agave inflorescences along with fields of green bushes and trees.  The assistant keeper's quarters are visible as a separate white building behind the inflorescences. (Marc C. Perkins)
Old Point Loma Lighthouse: From the south.

The two buildings visible in that image are the primary lighthouse (the multi-story painted brick building to the left) and the assistant keeper’s house (to the right).

The lighthouse and its tower are entrancing with their contrast and symmetry:

A somewhat cropped view of Old Point Loma Light as seen from the east on a crystal clear blue sky winter's day.    The bright white painted brick building contrasts with the clear blue sky and black lantern room.  The flagpole (currently lacking a flag) can be seen to the right of the house.  The windows of the lighthouse are just barely visible at the bottom of the crop.  While I generally prefer pictures of lighthouses either tightly cropped or whole with their surroundings3, I find this view of the house to be strangely entrancing.  It seems to be standing alone in front of a clear blue sky; what's before it and behind it are unknown, open to the viewer to decide. (Marc C. Perkins)
Old Point Loma Lighthouse: From the East.

The lighthouse started operation in 1855 with a Fresnel lens; its light was visible more than 25 miles out to sea.  The lighthouse currently contains the Fresnel lens from the Mile Rocks lighthouse that was moved to the lighthouse in the 1980’s and installed with the light offset by a few inches (so it’s not nearly as powerful as it should be).

The lens and latern room are gorgeous up close:

A close-up view of the lantern room and its attached black-painted balcony seen from beneath.  The lantern room appears to be towering above the viewer, and the details on the lantern room's green (copper?) roof are easily visible.  For instance, the room can be seen to have lion or gargoyle figureheads at each of the room's 10 corners, and above each window is a cut-out pattern in the roof's edging of what look to be waves heading towards each other with the cutouts themselves appearing to be horns.   A black ladder climbs to the top of the copper roof, reading the large dome on top.  The white, black, and green building contrast beautifully with the dark blue sky. The lighthouse is in Cabrillo National Monument near San Diego, CA.  I have another version of this same view that is less cropped, if you want. (Marc C. Perkins)
Old Point Loma's Lantern Room and Attached Balcony

I didn’t notice these fully while on the site, but when I processed the images I discovered that the edge of the tower’s roof is finished with beautiful details:

A highly-cropped detail view of my "Old Point Loma: towering lantern room" image.  This crop shows the beautiful details of the construction of the lantern room's room, including lion or gargoyle figureheads at each of the roof's 10 corners, and a vertical cut-out portion of metal above each window.  This cut out patterns appears to be made to look like a series of waves heading towards each other, with the cutouts themselves appearing to be horns.   The lighthouse is in Cabrillo National Monument near San Diego, CA.  As this is a severe crop, this image is not suitable to be printed exceptionally large (maybe up to 8 or 10" wide?), though the image it comes from can probably be printed up to 20"x30". (Marc C. Perkins)
Cropped detail view of "Old Point Loma's Lantern Room and Attached Balcony"

I love the cutouts on the roof’s edging, with their Escher-esque detailing. If you look at the metal itself, it’s cut into patterns of waves flowing into each other, yet if you look at the void spaces you can see either horns or birds (I see horns, Michelle sees birds). There are also gargoyles / lions at each corner of the roof. I wonder if these details are original, or a later addition.

Old Point Loma Light is in Cabrillo National Monument near San Diego, CA.  This image is made from just south of the assistant keeper's house, showing the points of both the roofs of that building and the main lighthouse with its chimney.  Behind these, standing tall, is the lantern room of the lighthouse, with its installed lens.  The bright white buildings contrast with the clear blue sky and black lantern room. (Marc C. Perkins)
Old Point Loma Lighthouse: Angles

As the lighthouse is no longer a functioning navigational light (it was decommissioned in 1891 due to frequent interference from fog), it’s open daily for people to explore. While the latern room itself is sealed off, visitors can climb the staircase to nearly the top of the lighthouse tower (to where the window is in the “From the East” picture above). Climbing lighthouse stairways is just awesome, and this one had a little landing Greg and I could set up on to photograph the beautiful symmetry.

Lighthouse staircases are just plain awesome, and Old Point Loma Light's stairway in Cabrillo National Monument is no exception.  Greg and I spent a good half hour up at the top trying various compositions, waiting for people to stop walking in, and admiring the Nautilus-like stairway.  To bring out the textures and lines I prefer this in black and white, especially since the colors aren't particularly grabbing. (Marc C. Perkins)
Old Point Loma Lighthouse: Nautilus Stairway

That was one cramped little landing with all of our gear set up, and we both had to wait quite a while for an opportunity to capture images of the stairs with nobody else in the tower. But it was worth it, and how could one possibly mind spending time inside a lighthouse? 🙂

I’ll leave you with a final overview image, showing the lighthouse and it’s rebuilt concrete water-catchment basin with native plant landscaping:

A wide-angle view of Old Point Loma Light as seen from the east on a crystal clear blue sky winter's day.  The foreground bushes mostly block the concrete water catchment basin.  The lighthouse itself is clearly visible, as is the assistant keeper's house (to the left).  Note: Please contact me if you're interested in purchasing this image for use printed or displayed large, as I should give you some background on the image (the sky has been burned to reduce uneven polarization, and it should be test-printed before final images are made). (Marc C. Perkins)

Oh, and if you want to see the scale of the stairway in the tower, here’s a self portrait of me in the stairway:

Some photographer got in my shot, darn it!

Stay tuned for more lighthouse pictures!

1 This will hopefully be the inaugural post of a multi-post series highlighting lighthouses I’ve photographed in the past year. And don’t get me wrong – the pelicans at La Jolla Cove turned out to be awesome.

Getting There

Cabrillo National Monument: Old Point Loma Lighthouse is in Cabrillo National Monument, which is at the end of Point Loma peninsula in San Diego, CA. The national monument’s webpage has an excellent directions page, including a great regional map. From interstate 5 you’ll need to take a few turns on city streets that aren’t necessarily well marked, so print out a good map or have your GPS handy. You’ll also be driving through an active naval base to arrive at the national monument, so park hours are strictly enforced. You’ll need to pay an entrance fee; parking was plentiful on site when we arrived on a winter weekday morning.

Waves crashing over the La Jolla Children’s Pool Beach sea wall

Greg and I walked to La Jolla Children’s Pool Beach (Casa Beach) back in January after we got our pelican pictures at La Jolla Cove. La Jolla Children’s pool is a small area of sandy beach that’s been walled in by a beautiful brick sea wall, apparently with the plan being that children could go swimming. Seals have had other plans for the beach, though, so there aren’t many children.

While I’m not entirely pleased with my seal pictures from the day, there was something else on view: waves crashing into the sea wall.

Water cascades over a brick sea wall at La Jolla Children's Pool, with its slightly rusty fence visible to the top.  A wave has just hit the wall, and white foamy water is flying over the bricks as the water crashes to the sea in front of the wall.  This contrasts with the perfectly calm blue water in the background. (Marc C. Perkins)
Crash of the wave; La Jolla Children's Pool, San Diego.

Big waves were somewhat infrequent, so I wasn’t able to get too many good captures, but I did get these two.

Water cascades over a brick sea wall at La Jolla Children's Pool on a gorgeous sunny winter day.  A wave has just hit the wall, and white foamy drops  are dripping and streaming off the bricks, as the water foams to the side and front of the wall.  The water and sky, though, are perfectly calm, making a great contrast. (Marc C. Perkins)
Cascade of the wave; La Jolla Children's Pool, San Diego.

My only problem is this: I can’t decide which picture I like better. Each time I look at the pair I pick one that I like, but then I wait a few days, come back, and find myself preferring the other one.

So, I need you, my kind reader, to solve this dilemma for me. Which do you like better?

Getting There

La Jolla Children’s Pool Beach (Casa Beach): Found in La Jolla (San Diego), the beach is (to quote Wikipedia) “located at 850 Coast Boulevard, at the end of Jenner Street, in La Jolla, California.” Greg and I left our cars in the lot we used for our pelican pictures (directions can be found in this post) and walked; it was a very pleasant 10 minute or so walk. I have no idea how available parking is in La Jolla or what would be the best location to park, so I can’t help you much; sorry. The beach can be freely accessed by walking down a few concrete stairs, but much of the beach’s sand is roped off to allow seals to lay on the beach unperturbed.

Aphids on oat grass

As I was taking my oat grass guttation pictures, I kept an eye out for cute critters on my newly planted grass. And, of course, there were some:

A small family of green aphids stands on the end of a stalk of tack oat grass, {Avena sativa}, that has a tiny drop of clear water at the tip (because it is guttating due to high-humidity).  There is one larger aphid (most likely a wingless parthenogenetically reproducing female, possibly a fundatrix) and six smaller aphids (probably her offspring / babies).  I'm not certain what species of aphid these are, but they may be {Diuraphis noxia}, the Russian Wheat Aphid.  Aphids are phloem feeding parasites, so this isn't a good sign for the grass, but I think they're absolutely adorable with their spindly little legs, long antennae, and red eyes.  So cute! Having just a couple of blades of grass blurred out of focus in the background gives context without distracting from the aphids.  The scale bar (lower-right) is 1mm long; a version of this image without the scale bar is available upon request. (Marc C. Perkins)
Home on the range: A small family of green aphids on an oat grass {Avena sativa} leaf. The scale bar (lower-right) is 1mm long.

That’s a young family of aphids, just starting out in life. Aphids are phloem-feeding plant parasites, so they’re sittin’ there having lunch.  They have a proboscis they insert into the leaf’s phloem vessels, which they then drink like a soda through a straw. Phloem is just about as nutritious as soda, so aphids have serious problems getting enough nutrition and dealing with the sugar overload, but that’s the topic for another post (and probably another blog …).

The larger aphid is almost certainly a parthenogentically reproducing female. She reproduces asexually, creating more daughter offspring from just her own unfertilized eggs. Yes, kids, that does mean that she can have baby aphids without any daddy aphids around.

So, the six smaller aphids (called nymphs until they mature) are almost certainly her offspring. The mother will keep producing more and more offspring asexually, and these offspring themselves will almost certainly be able to parthenogentically reproduce as well1. That grass stalk won’t be happy for long.

It can often be hard to tell from web-sized images how much detail is contained in the original capture. Since I know you’re thinking that these aphids are adorably cute, here’s a crop of the image above focusing on them (see the same crop as a larger image here):

This is a severe crop of my original "Home on the Range" image, highlighting the detail visible on the aphids.  A small family of green aphids stands on the end of a stalk of tack oat grass, {Avena sativa}, that has a tiny drop of clear water at the tip (because it is guttating due to high-humidity).  There is one larger aphid (most likely a wingless parthenogenetically reproducing female, possibly a fundatrix) and six smaller aphids (probably her offspring / babies).  I'm not certain what species of aphid these are, but they may be {Diuraphis noxia}, the Russian Wheat Aphid.  The scale bar (lower-right) is 1mm long; a version of this image without the scale bar is available upon request. (Marc C. Perkins)
Crop of my "Home on the Range" image; the scale bar is still 1mm long.

I’m not certain what species these aphids are, but I suspect they may be Diuraphis noxia, the Russian Wheat Aphid.

Oh, and the small drop of water at the tip of the grass stalk is there because the grass is guttating – exuding water from its tip due to root pressure. I write about that more in this post.

1 Winged and/or sexually reproducing individuals can also be born, typically when environmental conditions change dramatically (e.g., the onset of winter, or depletion of the food source).

I personally donate to the Humane Society, and am happy to help a good cause. As such, in addition to entering my images into their judged category, I’ve also entered them into their “fundraiser” competition. In this competition the entries compete for votes, which can be obtained by donating to the Humane Society:

“Kira”

Vote

“Lucca”

Vote

There’s no way I can win the fundraiser category, and I don’t want to try1. Instead, I want to use this as an opportunity to give you an excuse to donate a little something to a worthy cause. And, just to reinforce the idea that I’m not in this for the fundraiser competition prize, if I do somehow win I’ll donate the prize (an iPad 2 and iPod) to the Orange Coast College Disabled Students Center.

The contest ends February 29 at 10:00pm EST, so donate before then if you desire (by following the links above).

1 Votes are tallied per individual picture, not per photographer. So, by posting two pictures I’m possibly splitting any votes I get. But this way you get to vote for your favorite of my two cats!

Cat eyes on a Friday

Last weekend I got a few more pictures of my cats, this time focusing on the eye (as opposed to the tongue or third eyelid). Lucca was a great model with her beautiful green eyes and blue patched tabby and white fur:

A closeup of Lucca, a blue patched tabby and white shorthair house cat, looking up at something exciting.  I like her attentive, alert expression that shows off her cute "old rose" nose and her bright green eyes.  The fur on the top of her nose is also in sharp focus, showing off the different directions it lays.  The background is off white, and out of focus. (Marc C. Perkins)
What's up there?
This vertically-cropped image is a closeup of a blue patched tabby and white domestic shorthair cat's face, focusing on the eye.  I don't take too many vertical images of my cats up close, and often don't like them, but this is an exception. (Marc C. Perkins)

Botany demonstration: Guttation in oat grass

My cats love to nibble on grass, and so I grow tack oats (Avena sativa) from seed for them. About six months ago I figured out that on cool, humid mornings the grass could be seen guttating. At the time I lacked my macro lens, and so did the best I could and got this image.  It’s an okay image, but I don’t like the choice of background in retrospect, and I also wanted to get in closer and show just a few stalks of grass so the water drops would be more obvious.

Over the weekend some newly planted grass was again demonstrating guttation, so I tried anew:

Three stalks of tack oat grass {Avena sativa}  with large drops of clear water at their tips stand against a black background with multiple other strands of grass blurred out of focus in the background.  The water is present because the grass is guttating; guttation is a process wherein plants release water at the tips of their stems due to root pressure.  I like how the other strands of grass give the image a feeling as though it's taken in a lawn or field of grass, without distracting from the primary element (the guttation).   This is an uncropped image, so it should be able to be enlarged to print at 16x24" easily. (Marc C. Perkins)
Three stalks of oat grass demonstrating guttation.

Guttation is caused by root pressure building up so that water is squeezed out pores (hydathodes) at the tips or sides of a plant’s leaves. It typically happens at night, under cool, moist conditions when the soil is well hydrated. As Wikipedia says, it’s important to note that guttation and dew are two completely separate phenomena.

To demonstrate guttation in a typical botany science lab , a technician sets up a few-weeks-old pot of grass under a bell jar, waters it thoroughly, and leaves it for the night. The next morning tiny drops of water cover the plant’s leaves.  One thing I like about my example is that it’s  free of lab manipulation: this pot of grass was just sitting  on my porch when I saw the guttation and brought it in to photograph.

Two stalks of tack oat grass {Avena sativa} stand against a black background with large drops of clear water at their tips.  The water is present because the grass is guttating; guttation is a process wherein plants release water at the tips of their stems due to root pressure.  This closeup also includes a tiny strand of spider silk connecting a hook on the top-most blade of grass to an unseen blade of grass off-camera left.  This image is on a clean black background, with only two other strands of grass even in the frame, and both of those are blurred out of focus to not detract from the two primary focal points.  This is an uncropped image, so it should be able to be enlarged to print at 16x24" easily.  The scale bar (lower-left) is 1mm long; a version of this image without the scale bar is available upon request. (Marc C. Perkins)

If you’re curious how I photographed these, I used a technique much like1 that used with my poinsettia flower closeups; see my behind the scenes post for more details.

1 The first image is a single-frame capture; the second is a multi-image blend to increase depth of field. Both use a studio setup almost identical to the poinsettia setup, except I used reflected direct sunlight to aid in illumination.

The Brooklyn Bridge

Last month I spent a few days in New York City visiting family.  One afternoon we walked over a bridge.  You may have even heard of it.  Apparently it’s called “Brooklyn Bridge”.

You have heard of it?  Huh.  Surprising.

So, yeah, we walked over the Brooklyn Bridge.  And I had my camera with me.  You know what’s coming.

The Brooklyn Bridge seems like one of those places like Half Dome: it’s been photographed by every photographer who’s come close to it since silver was capturing photons.  I figure that by now every angle from every position in every lighting condition at every time of the day has been photographed (at least from the pedestrian walkway).  So, when we decided to walk over the bridge I wasn’t super excited about getting lots of pictures.  I figured I might take a few “I was there” shots, but that’s it.  After all, we were on our way to Murrays’ to get cheese.

We got on the bridge, and I was blown away.  It’s full of contrasts: stone and steel, cables and ties, pedestrians and cars, water and sky, clouds and sun.  And I’ve never seen so many leading lines in a single location.  My heart went aflutter.  

Construction barriers (?) line the pedestrian walkway as it approaches the first major tower as pedestrians walk along the bridge.  The line on the wooden path demarcates where pedestrians walk (on the left), and where bikes can ride (on the right).  This angled shot include a lot of patchy cloudy sky (with blue peeking through), one of the lamp posts, and a proudly-waving American flag on top of the tower flat out for the viewer to see. (Marc C.

Let’s just say that I took a “few” pictures, and leave it at that.

It was a blustery winter day, and as I walked the bridge I was awed by its age and grandeur that was mixed with city grit and grime. I tried to capture that feel with some high-contrast black and white processing in this image (which looks better viewed larger on my gallery website’s page for it):

I loved my visit to New York City, and walking across the Brooklyn Bridge was a highlight.  A strong wind was blowing, and the old brick, wood, and steel just cried out for photography.  This image focuses on the symmetry of cables and towers, with an American Flag blowing right at the viewer from the top of the tower.  I processed this in black and white to emphasize the dark, gritty feel of the old bridge.  The "1875" date marker is easily visible in the image.  NOTE: This image has a black border embedded into it for web display; please contact me if you're interested in ordering this image so I can print it without a black border. (Marc C. Perkins)

The flags on top of the towers were blowing beautifully in the wind for most of the walk, making me have to play with the cables as leading lines on a cloudy, gray background.

But as with the bridge, the day was full of contrasts. As we continued walking the setting sun broke through the clouds for a precious few moments to cast a brilliant orange glow on the cables and brickwork, as the Financial District and the new 1 World Trade Center rose in the background:

As I was walking across the Brooklyn Bridge near sunset on a dark, cloudy day, the sun broke through the clouds and illuminated the bridge for a magical few moments.  In front of me a couple was walking, and it created this image of the bridge: patchy clouds with blue sky in the background over the financial district in Manhattan, the lines of the bridge in the foreground, and the couple sealing it all together.

I’m happy I was one of dozens of folks with DSLR’s on its pedestrian walkway that day. Oh yeah, and we did get to Murrays’ in time to pick up some good cheese.

Behind the scenes: How I took my poinsettia flower closeup picture

New feature alert: I’ve always enjoyed reading other photographers’ “behind the scenes” and tutorial posts, so from now on I’ll occasionally post them.  This post focuses on the “studio” and exposure blending techniques I used to create a macro image of a poinsettia flower.  

Introduction

Last month I wrapped up a three-post series on poinsettias (post 1, post 2, and post 3).  The images for the first two of these posts were taken back in December in an Orange Coast College Ornamental Horticulture greenhouse, which was a great location to work in as it had slightly directed diffuse light (sun shining through semi-opaque panels at the top of the house) and hundreds of plants to hunt through for specimens.  Unfortunately, though, poinsettias have separate male and female flowers, and only the male flowers were visible during that shoot.

Thus I had to keep a plant at home and wait.  About a month later the female flowers had emerged, and I was able to get some images and finish the series.  The highlight of the series (for me) is this closeup on an inflorescence that demonstrates all of a poinsettia flower’s anatomy in a single image.

The image:

A single female poinsettia flower with stigma, style, and enlarged ovary can be seen emerging from its involucre (cluster of bracts fused together) on a thick pedicel (stalk) that's almost as long as the flower itself.  Also emerging from the involucre are a number of withered male flowers (stamen and anthers both visible) that still have yellow pollen on them.  The involucre has a nectar gland emerging from it (that look like two yellow lips).  The involucre also has small saucer shaped structures emerging from it; I'm not sure what they are (they're more easily visible in my other poinsettia pictures).  The entire inflorescence (involcure, male flowers, and female flower) is called a cyanthium.  The cyanthium is growing up from a stem's branching point, where a bract is emerging.  The red leaves surrounding the inflorescences (mostly out of focus) are bracts.  The scale bar (at the bottom) is 5mm long. (Marc C. Perkins)

The red leaves surrounding the inflorescence (mostly out of focus) are also bracts. The scale bar (at bottom center) is 5mm long.

Lighting, equipment, and setup

Getting the shot was not trivial. First, I didn’t have access to the greenhouse, but needed to get similar lighting to maintain consistency between the images in the series. I found good lighting in a room of my house that faces east, and has white curtains and bright walls. In the early morning the sun hits the curtains and diffuses through the room nicely (while maintaing some directionality to the light).

I used my Canon 60mm ef-s macro lens in manual-focus mode, and determined the base exposure and set a custom white balance in-camera using a gray card (see this post by Greg Basco for why setting a custom in-camera white balance is useful). Said gray card was photographed out of focus, so it also served as a test for dust spots (which can be deadly during exposure blending for depth of field).

I’m tired of taking macro photographs with my camera hanging down from the tripod, so I supported the plant on a chair a few feet from the window, with my camera in between the window and plant. This allowed me to move either the plant, tripod, or tripod head to adjust framing.

Framing closeups of plants is tedious, as leaves and other structures often get in the way and cover up important anatomy. I put some leaves underneath the lens to corral them, but a few others kept popping up annoyingly. My solution was to weigh them down with my lens cap. High tech, I know.

The background was another issue. It was clearly going to be out of focus, but I needed the color to not be glaring. For the first two shoots in the greenhouse I simply grabbed an additional poinsettia or two and put them behind the first plant. Voila! Instant matching background.

For this shoot my first background was a white closet door. The white became a bit jarring for the composition above, though, as there were just a few white spots shining through the red bracts. So, I grabbed a black shirt and hung it on a chair behind the plant. The background disappears, and you probably didn’t even know there was a black background behind the bracts (which is exactly what I wanted).

Here’s a picture of the setup:

Settings and image capture

Next came the old debate of settings. I wanted sharpness and depth of field, and didn’t care a whit about exposure time thanks to being indoors and able to turn off the wind (read: turn off the heater). I’ve found that the lens is sharpest around f5.6 – f8, but at the focal distance I wanted to use my depth of field at that aperture is miniscule. For the first images of the day I was able to get everything I wanted in focus composed in a single plane, and thus I pushed the aperture to f11 and f13 for a bit more depth of field in a single image with acceptable sharpness.

But for the image above I needed more depth of field, thanks to that giant ovary and large cluster of male flowers. Thus, I fell back on my old standby: image blending for depth of field. Greg Russell has a great tutorial on image blending which summarizes the technique beautifully.

The technique I used boils down to this: I started by setting the focus and exposure to manual and focusing on the closest subject I wanted sharp (the pollen grains on the front of the ovary). I then took a series of images at f8, adjusting the focus backwards by as small a margin as I possibly could as I focused through the range I wanted sharp.  Using a macro-rail tripod head to change the camera’s position as I changed focus would have been ideal (since the field of view of the lens changes as it focuses), but as I lack a rail slider I couldn’t do that.

As a side note, assuming that you don’t have a rail slider, always compose your exposure-blended images at the closest focus you plan to use.  That’s the focus with the narrowest field of view, and thus the one that will most likely limit your cropping post-exposure-blend.  

Processing

I then imported all the RAW images into Lightroom 3.6 and did my typical adjustments (white balance, exposure, black point, brightness, contrast, saturation, noise reduction, spot removal, etc.).  I shot a series of 11 sequential focal planes on this particular composition, but ended up choosing only the first eight to use for the final product, as the last three put distracting elements of the flower into sharp focus.  I know some people who exposure blend try to get everything in focus (creating infinite depth of field), but I often find this to be distracting; having the background and foreground out of focus provides depth to the image (and also isolates the subject).

Here are the eight processed images that form the base of the final image:

Exposure blending

I used Lightroom’s “Edit in Photoshop as layers” feature to get the adjusted images into Photoshop CS5, aligned the layers using Photoshop’s built in tool (Edit / Auto-Align layers), and then blended the layers for depth of field (also using Photoshop’s built in tool: Edit / Auto-Blend layers).

Exposure blending rarely works perfectly on the first try, though, so I looked through the blended image at 100% to check for errors. Sure enough, there were a bunch: a few “points of light” where photoshop puts a bright spot into the image near the edge, and also a few areas where Photoshop chose the wrong layer to use (thus adding an out-of-focus area into an area that should have been in-focus).  Here’s what two of them looked like:

Close-in (100% crop) views of two blending errors Photoshop CS5 made while blending my eight-image Poinsettia female flower series.  On the left Photoshop has selected a line of the plant at the correct focus, but then used incorrect focal planes for the remainder of the stem.  On the right photoshop has added what I call "points" or "bars" of light; blending errors (often near the edge of an image) where Photoshop inexplicably adds in a bright streak or point. (Marc C. Perkins)

On the left Photoshop has selected a line of the plant stem at the correct focus, but then used incorrect focal planes for the remainder of the stem (both above and below the in-focus portions). A single image has everything from the in-focus portion up perfectly in focus; Photoshop has just chosen … poorly.  On the right Photoshop has added what I call “points” or “bars” of light, blending errors (often near the edge of an image) where Photoshop inexplicably adds in a bright streak or point.

To fix these I un-did the blending, found the incorrect layers Photoshop had used, and erased the parts of those images Photoshop had selected. Then I re-blended the image, checked again, and continued this until I got an image I was satisfied with.

Scale bar

To add the scale bar I captured a separate image with a ruler in the frame next to the flower (after I had finished shooting, since putting the ruler in the frame could easily damage the flower), then copied that image as a layer onto the final blended image and made sure the flower was precisely the same size in the ruler image as in the blended one.  A quick use of the line tool got me a subtle scale bar that I could move wherever I wanted in the blended image.  I chose to put it in the shadows near the bottom, so it’s visible, but you have to look to find it.

Final notes

And that’s it; head back to the top of the post to see the final product!

Using this layer blending technique is a bit cumbersome, but it allows me to maintain optimum image sharpness while precisely controlling the depth of field (by choosing how many focal planes to blend together into the final image).  It’s worth doing, but only for those images that really need it.

Thanks for reading!  I’d love any suggestions, and would be happy to answer any questions.
