This is another one of the performers from Steam Powered Giraffe. This one's character is called Upgrade.
Technical info: Shot with a Nikon D40 and Nikkor 55-200mm VR DX lens, in aperture priority exposure mode. Focal length 165mm, aperture f/5.3, shutter 1/160 sec, ISO 200. I added a similar blurred overlay layer in Photoshop CS5 to enhance contrast and give it that soft glow, but I also used a layer mask to apply it just to the midtones. (Duplicate layer, apply Gaussian blur with radius 5, set layer mode to overlay, apply layer mask, apply image to layer mask, solarize layer mask, move layer mask white point to the left, flatten image.) After that, I used the vignetting tool in Aperture 3 to darken the background. This left her coat too dark, so I brushed the adjustment out of the bottom of the picture.
Thoughts for improvement: This looks pretty good on my laptop, but on my work monitor (which is dark and uncalibrated) it's way too dark. I should probably have increased the brightness or exposure in post, or just had a better exposure to begin with.
