As I was creating yesterday's post about the New York Public Library releasing 180,000 images into the public domain, I began thinking of ways in which the wide range of images could be used.
With a primary interest in portraiture, the first idea that came to my mind was incorporating one of the public domain images in a portrait simulating a multiple exposure. With that in mind, I picked up my 5D Mark III and favorite portrait lens – the 85L II – and captured a profile of Amanda lit with a 580EX flash diffused by a small soft box positioned in front of (and slightly behind) her and another flash pointed at the background. This left me with a significant portion of Amanda's profile in shadow, meaning that I could use a public domain image set to a Lighten blending mode in Photoshop CC to easily blend the two images.
After cleaning up the background (making sure it was completely white) and a few adjustments (including a Black and White adjustment layer), the base image looked like this:

The New York Public library recently released 180,000 of its digital scans into the public domain. The works include manuscripts, sheet music, stereoscopic photographs as well as maps that are free to use for any purpose.
These images should be especially useful to those photographers who like to combine and overlay images for graphic art or illustration purposes. A rather interesting tool for browsing the images can be found here. [Sean]

Example:
While attempting a few macro shots yesterday, I was inspired to turn my lens on a subject that has always fascinated me because of its intrinsic beauty and complexity – the eye.
Gear Used
EXIF: f/10, 1/80 sec, ISO 320
Thought Process and Execution
As I wanted a macro shot of the eye, my lens choice was easy. However, as I wanted to get as much magnification as possible, I stacked all three of the Kenko Extension Tubes behind the lens. This shortened the minimum focus distance allowing me to get even closer to the subject for a larger than 1.0x maximum magnification.
How much larger? Well, let's see.
With the Canon EF 100mm f/2.8 Macro USM...
Update: I revised this section to make the calculation simpler.
Magnification = Native Maximum Magnification + (Extension Length / Focal Length)
Magnification = 1.0 + [(12 + 20 + 36) / 100]
Magnification = 1.0 + [68 / 100]
Magnification = 1.0 + .68
Magnification = 1.68
Note that the magnification value assumes we are working at Minimum Focus Distance.
Another factor we need to consider is the effective aperture in this scenario. As magnification increases, the effective aperture gets narrower. Here's how the effective aperture is calculated:
Effective Aperture = Aperture Setting + (Aperture Setting * Magnification)
Effective Aperture = 10 + (10 * 1.68)
Effective Aperture = 10 + 16.8
Effective Aperture = f/26.8
Working with this kind of magnification brings with it a couple of challenges. One challenge is that your depth of field becomes very thin. Even at f/10, there's only a sliver of the image that's in focus (the reflection of the top eyelashes). And on top of that, a higher than 1.0x magnification makes the viewfinder very dark. Minimal DOF combined with a dark viewfinder makes precise focusing a challenge to achieve.
And because of the very narrow effective aperture, a lot of light is needed for a proper exposure. In this case, I used a manually controlled, shoe-mounted Canon 580EX set to nearly full power (at ISO 320) in order to obtain a decent exposure. Of course, the RoundFlash Ringflash Adapter I was using resulted in a certain amount of light loss from diffusion, but I felt it was the best modifier for the look I was going for and well worth the penalty of a slightly higher ISO.
As far as the shutter speed goes, there was no specific reason I chose 1/80 second over anything else. In this particular instance, any reasonably fast shutter speed would work (even one that would likely show motion blur during at normal magnifications). That's because the light captured in this scene is provided entirely from the flash which has an extremely short duration. In effect, the shutter speed was the flash duration.
I typically use a tripod when shooting macro subjects. But in this case, using a tripod seemed a bit impractical. That's because with such a small DOF, I thought it would be easier for me to adjust the camera back and forth slightly to achieve focus rather than try and direct the subject to move her head the same amount. I also typically use 10x Live View to aid in manual focusing when shooting macro subjects. But in this case, using 10x (or 5x) Live View would have had two big consequences: the inability to see the entire framing and a loss of stability needed for precise manual focusing (as my eye would not be on the viewfinder).
I overcame focus challenges by sitting on the coffee table in front of the subject and bracing my elbows against my knees with the camera pressed firmly to my face. This gave me a relatively rigid platform where I could sway ever so slightly forward and backward as the subject stared straight into the lens. This also allowed me the ability to easily adjust framing on the fly for slightly different looks between shots. I concentrated on timing my shots when the reflection of her top eyelashes looked sharpest (a challenge with the dark viewfinder, but not impossible). After several attempts, I finally had the framing and focus that I wanted.
In post-processing, I increased clarity to help bring out details in the iris, upped the saturation a little and made relatively minor adjustments to brightness/contrast. The image is uncropped.

Pittsburgh, home to three rivers (Ohio, Alleghany and Monongahela), is also home to great reflections and many bridges. The reflections of the city, however, are usually color blurs due to wakes from boat and barge traffic. Thanks to the wave-rebounding solid vertical river walls, the waves seem to never dissipate and when planning this long daytrip, I was visualizing a creamy-smooth river of color during the blue hour and later. What I found on this day was ... no boat traffic and very different images than I had visualized. Different in a good way, I think.
The most difficult part of this image capture? Being there.
To take the actual picture, I simply stood on the north shore of the Three Rivers Heritage Trail river walk, centered between the Robert Clemente and Andy Warhol bridges, set the aperture to f/16 to get the star burst effect from lights, adjusted the framing to level (both pitch and yaw to keep the buildings and their reflections vertically straight) and pressed the shutter release (mirror lockup with 1 second delay).
The RAW file post processing was not challenging. In DPP, highlights were reduced (-5), shadows were boosted (+5) and saturation was added. While this result was very good, I opted to brighten the reflection in the water slightly (1/3 stop) using a simple HDR process. Two 16-bit TIFF files were created (one at -.83 EV and one at -.5 EV) and combined in Photoshop.
Being in Pittsburgh for the day meant renting a car the night before (4 drivers with 2 cars is not working so well), driving 4 hours, hiking roughly 3 miles with a full MindShift Gear BackLight 26L (including two tripods, extra cloths, food and water) and overall, being outdoors for 9 hours with temperatures in the teens and twenties (°F). I arrived home at 2:30 AM and got up to return the car in the AM.
The beauty of our brains is that, in a few days, the only thing I will remember is having spent a great day in a beautiful city and the images will last for a lifetime. I'm ready to go back.
Another beauty is the Sigma 20mm f/1.4 DG HSM Art Lens that I was "focused" on for the day. I referred to this lens as a "scapes" lens and it performed excellently in its cityscapes roll this day.
