Science uses one of my images

This week’s Science, the preeminent scientific journal, features one of my images:

A mouse scratching its face on Science's website
A screen capture of Science’s March 10, 2017 issue’s website (used with permission of AAAS).

The image is being used to illustrate the accompaniment to an article on contagious itching in mice.  This is now my second image publication in Science; the first was a looser crop of this image, used to illustrate the accompaniment to an article on limb digit developmental patterns.

Many thanks to the editors of Science for being repeat customers of my images!


And, for the photographers out there who want to know how I did this, the answer is sadly low-tech: I posted a keyword-rich album of mouse closeups many years ago on my Photoshelter website, and the art associates / designers of Science found me.  They e-mailed me with an urgent request, and both times we had a contract and price agreed on within a few hours of their first e-mail.

Two intersections in Diamond Bar: The Grand Avenue Beautification Project

In 2015 the city of Diamond Bar completed their Grand Avenue Beautification project, which included redesigning the medians and parkways of the Grand Avenue / Diamond Bar Boulevard and Grand Avenue / Longview Drive intersections. The landscape architecture work was done by David Volz Design.

Happily enough, Diamond Bar Boulevard aims directly at Mt. Baldy, creating a view no photographer can resist*:

Rocks, median art, and flowering plants (yellow yuccas - Hesperaloe parviflora) are all visible, including a car. The stoplight is showing all green lights and a green left turn signal. This was part of the 2015 rebuild of the Grand Avenue and Diamond Bar Boulevard intersection for Diamond Bar's 2015 "Grand Avenue Beautification" project, landscape architecture for the project was by David Volz Design.

The Longview Drive intersection is at the eastern edge of the city, and features a new entrance sign for the city:

The sign is pretty just after sunrise, but the copper elements really stand out when it’s diffusely lit:

Iron plates form a repeating theme through the project, serving not just as elements on the entrance sign, but also as artistic inserts on parkway columns, display pieces in medians, and tree grates.

Polaris above Prescott Valley, AZ

When I first started reading up on night photography years ago I remember looking at star trail images with wonder: simply by leaving the lens open for a long time one could capture the movement of the stars across the sky.  Even more wondrous were images that included Polaris, the north star, which aligns with the planet’s rotational axis and thus does not move during the night (while all the other stars appear to spin around it).  I promptly put capturing a long-exposure star-trail image with Polaris on my bucket list.

And last week while visiting Prescott, AZ, I finally got one I’m happy with:

A long-exposure night image with moonlit illuminated hills and stars rotating around Polaris.
A long-exposure image of the moonlit hills above Prescott Valley, Arizona.

This is a single-frame capture based on a roughly 30 minute exposure; the hills in the foreground are illuminated by moonlight.

Take a look in my Prescott, AZ gallery for a few more images from my recent trip there (though this is the only star trail image I’m sharing from the trip).

Memories: Journal of Feline Medicine and Surgery uses my images

I got a little reminder today of a neat use of my images: the Journal of Feline Medicine and Surgery purchased two of my cat tongue closeups to illustrate an article on the medical implications of cat hairballs.  The article was behind a paywall when it was first published, but the full text is now freely available.

Here’s the reference:  Cannon, M. 2013. Hair Balls in Cats: A normal nuisance or a sign that something is wrong? Journal of Feline Medicine and Surgery 15: 21-29. doi: 10.1177/1098612X12470342.   http://jfm.sagepub.com/content/15/1/21.abstract

 

A portion of Newport Beach's skyline at night

Newport Beach at Night

Lately I’ve started bicycling longer distances1, and as I’m riding, I’m seeing more of my local area. So many of the bicycle paths lead to stunning views, not to mention the gorgeous little parks.

But now that it’s winter I’m out riding a lot at night. Night changes so much about the landscape, especially in urban areas where a single bright point-source of light (the sun or moon) is replaced by multiple small light sources, many of which are different colors and intensities. Combine the change in illumination with a requirement for long exposure times and you have a recipe for a dramatic visual change.

I wanted to try to capture some of that changed beauty, so I recently biked to a couple of my favorite vantage points in Newport Beach to try my hand at it.

Saddleback Mountain (Santiago Peak and Modjeska Peak) can be seen off in the distance, to the left.  This image is a minimally manipulated single-frame, long-exposure capture.

Pacific Coast Highway (PCH) is visible in the foreground, as are many of the buildings on the Balboa Peninsula's western portion.  The two tall buildings on the left are the  the Vista Del Lido complex and the 601 Lido Condominiums; the two tall buildings on the right (that almost appear as one) are Newport: The Towers (3121 PCH) and Newport Surgery Center (3333 PCH).

But those are just general overviews; the image I’m happiest with takes just a piece of one of those and lets your eye linger on the details:

In the foreground are buildings surrounding the Pacific Coast Highway (PCH); the back of the 2436 Pacific Coast Highway office building (that looks like a motel) is prominent, as is the Bayport Yachts round turret and Joe's Crab Shack.  Behind that are buildings on Newport Peninsula / Balboa Peninsula that front Newport Harbor, most striking among them is the multi-story Blackman Ltd. building at 3388 Via Lido Drive, with the parking structure at the Lido Marina Village on the right.  Behind those buildings and the palm trees lie two open-ocean oil platforms (one above the Blackman building, and one above the parking structure), which almost look as if they're floating in space.  This image is a minimally manipulated single-frame, long-exposure capture. (Marc Perkins/Marc Perkins Photography)

All of these are single-frame exposures with minimal manipulation in post processing. A few more images can be found in my Newport Beach at Night album.

Gulf Fritillary: butterfly of many costumes

While out in the garden this weekend I spotted a gulf fritillary, Agraulis vanillae incarnata. They’re stunning butterflies:

A gulf fritillary [Agraulis vanillae incarnata] hides amongst blades of lemongrass [Cymbopogon sp.].  It looks like it's hyper aware; stalking prey (even though it's looking for nectar …).  The bottom of this species' wings have beautiful spots that reflect silver in bright light (as you can see in this image), but are white in the shade.  The forewings are also partially red. (Marc Perkins)

What first caught my eye was the silver reflections of the spots on the bottom of their wings. In direct sunlight it looks like they’re metallic; very eye-catching. But when the same butterfly is in diffuse light, those spots look white:

A gulf fritillary [Agraulis vanillae incarnata] stands on a [Ficus] leaf.  The spots on its wings when closed are white in the shade (as in this image), but reflect light to appear a beautiful silver when illuminated.  When its wings are closed, the bright orange and red colors of the butterfly are completely hidden. (Marc Perkins)

Compare the first and second picture, and you’ll see that in addition to changing from metallic to white, the butterfly can also choose how much color to show on its underside. When it spreads its wings (as in the first picture), the bright red/orange coloration of its forewing is revealed; but when it rests with both wings pulled together and upright (as in the second picture) it can completely hide the red/orange color, thus showing only brown and white/silver. It can also partially separate the wings, to reveal just a bit of color (as it liked to do when it was annoyed with how close I was getting).

And speaking of color, check out the top of those wings:

A gulf fritillary [Agraulis vanillae incarnata] stands amongst blades of lemongrass [Cymbopogon sp.] with its wings outstretched, showing off its bright orange colors. The bottom of its wings have silver spots on them, not visible in this picture. (Marc Perkins)

This butterfly only held open its wings for a few seconds after each flight attempt, so spotting the true colors of the wings takes finding one in flight and then watching it land.

For a fourth, and final, view of the gulf fritillary, how about a head-on look?

Sleek and slim, complete with a coyly resting forelimb.

And in case you didn’t realize, all four of these images are of the exact same individual. It’s surprising how different it looks depending on angle and lighting.

The larvae reportedly only eat passion flower vines; I wonder which of my neighbors has one.

It’s a bee!

It’s been a busy summer without much time for photography, but today I grabbed the camera and headed for my garden. I was happy to capture this closeup:

A bee (likely a honeybee; [Apis mellifera]) climbs a marjoram ([Origanum majorana]) inflorescence.  The bee's eye, antennae, wings, legs, and fine body hairs are all in focus, as are the pistils and stamen of some of the marjoram flowers. (Marc Perkins)

That’s a bee (likely a honeybee, Apis mellifera) on a marjoram (Origanum majorana) inflorescence.

Look at those antennae (I love the ball joint at the base), those big eyes filled with ocelli, veined wings, and all those lovely little hairs. She’s a beauty!

Many thanks to my good friend Hannah, who gave me a set of wireless flash triggers that played a key role in capturing this image.

How to convert a child bike trailer into a cargo trailer: an illustrated guide

I’ve been trying to do more of my errands by bicycling, and one of my biggest holdups has been a lack of cargo room: it’s hard to lug home 80 pounds of cat litter in a backpack. So, a few months ago I started shopping on Craigslist for a bike trailer, only to find out that a good friend had one in her garage that I could have for free.

My Schwinn Spirit bike trailer before modifying it to had a wooden platform to carry cargo. (Marc C. Perkins)
My Schwinn Spirit bike trailer before modification.

That’s a Schwinn (Pacific Cycle) Spirit Bicycle Trailer, rated to hold up to two 50-lb kids (aka: 100 pounds of cargo!). I immediately fell in love with it, and even used it to lug home 80 pounds of cat litter from the pet store:

Two 42-pound bags of Fresh Step cat litter strapped in like kids into my bike trailer's child harness.  So cute! (Marc C. Perkins)
Two 42-pound bags of Fresh Step cat litter strapped in like kids into my bike trailer's child harness. So cute!

An unexpected bonus of the trailer is that whenever I have it attached to my bike, cars give me more maneuvering room. I bike on city streets in Orange County, CA, and am used to having only a few inches of space between my side mirror and the cars zipping past me. But when I’m using the trailer, most cars will actually change lanes before even attempting to pass me (or at least give me four or five feet of clearance), and I’ve had multiple people literally stop to let me go in front of them. Amazing.

But using the trailer for cargo has proved to be less than ideal, as the bottom of the trailer is just made of soft fabric: the kids’ weight is designed to be supported entirely by the harness (which is hung from a horizontal metal rod). So, unless I had cargo that was perfectly sized to fit into that harness (like the bags of cat litter), I was limited to low weight.

The Schwinn Spirit bike trailer has a lot of flat, open room in it once the child harness has been removed. (Marc C. Perkins)
The bottom of the Schwinn Spirit bike trailer (with the child harness removed) is just thin fabric: not good for cargo.

So, I wanted to modify the trailer to add a solid base to convert it to a cargo trailer, and while I found lots of DIY tutorials, they all involved removing the fabric. However, I wanted to keep the fabric on my trailer to protect my cargo from weather and prevent it from blowing around. Additionally, my guess is that the extra space I’m getting when I use the trailer is due to both the visual bulk of the trailer (it’s actually the same width as my handlebars, but makes my bike look much wider) and also because people think there are cute wittle children in the trailer and thus are panicked about the possibility of hitting them1.

So, what I ended up doing is removing the harness and adding a wooden shelf that fit inside the existing fabric, so my trailer now looks like this:

A view of my DIY bike trailer modification from the front looking in.  The shelf is high enough that it doesn't hit the fabric on the bottom of the trailer, but low enough to hold a large amount of stuff.  As a bonus, the shelf is hard to see, so drivers don't know there's not a kid inside :) (Marc Perkins)
My finished cargo trailer!

First tomatoes of the year: a lighting comparison

Michelle and I tend our backyard garden every summer, and one of our joys is seeing the first produce of the year slowly ripen on the plants. Just this week our first cherry tomatoes (Solanum lycopersicum) are finally ripening, and so yesterday I took a few pictures of the glorious first fruits:

The first fruit of the year in our garden: two deliciously orange cherry tomatoes still "on the vine" (attached to the plant).  This plant is a "sun sugar" variety of tomato (Solanum lycopersicum) that we purchased from Orange Coast College's ornamental horticulture department.  This picture was taken in the field using natural lighting to create an in-vivo look. (Marc C. Perkins)

The tomatoes were in some nice diffusely-lit shade, and that’s what you see above – I used a tripod to stabilize the camera, but otherwise didn’t need anything else.

But since I’ve been having fun experimenting with off camera lighting recently, I decided to pull out my lighting gear and try some “studio” style lighting on the fruits.

This picture was taken in the field using studio lighting (off camera flashes) to create a more dramatic look. (Marc C. Perkins)

Those are the exact same fruits in the exact same position, but now they’ve been lit using the “invisible black background” technique I’ve described before1.

What a difference lighting makes! The black background makes the fruits pop out visually, thanks to less visual clutter, but I think it also makes the scene look more artificial (or as though it was taken at night). My favorite comment so far comes from my dad, who said that the fruit look like two “hot Jupiters”. Little tomato planets floating in space; I like it.

Footnotes

1 Two snooted flashes were setup, one on either side of the fruit, and I used my gray card to shade the background from the primary flash’s illumination. Both flashes also had great natural gobos: the branches of the plant itself.

Chainmail: Behind the scenes of getting a perfect black background

As I’ve posted before, Michelle loves to make chainmail. So, it wasn’t a surprise when she recently asked me to take a picture of her latest project1:

A european 8-in-1 copper chainmail bracelet with a sliding clasp.
A european 8-in-1 copper chainmail bracelet with a sliding clasp.

For the purposes of this post, note the background: it’s seamlessly black, with nothing at all visible. And that background was created with no work at all in Photoshop (other than removing a string I used to support the project) – it was created solely by careful placement of off-camera lights. As the method is pretty neat, I thought I’d show you how I did it.

The first technique most people think of for getting a black background is to, well, put something black behind the object. While this works, it requires careful lighting and spacing to ensure that the black object doesn’t become visible (as more than just solid black) in the image. I did just this outdoors with my amaryllis flower bud images, but I had to find flower buds with enough shaded space behind them to hang a black T-shirt on a spare chair well behind the depth of field of the image, and then whenever stray light hit the T-shirt you could see the folds in the fabric. Annoying.

For the maille bracelet I created a black background by putting absolutely nothing behind the maille. And I mean literally nothing: here’s what the maille looked like as I was setting it up:

A picture of the copper european 8-in-1 maille project seen in natural room lighting in my "studio".  The background has a colorful picture, lights, and other junk in it, which disappear thanks to the off-camera flashes which create an "invisible" black backdrop. (Marc C. Perkins)

That is the exact positioning used for the final image you saw earlier, and yes, that is my living room wall 10′ behind the project. And a brightly colored lithograph. And IKEA lamps.
