Description


model: Julie Simone November 2, 2007 in Washington, D.C. This is one of my favorite pictures from my shoot with Julie. It's also one she likes a lot too. For those playing along at home, to create a BW I take the original color image and split it into three channels using the LAB color space. The LAB model has an advantage over the more well known RGB and CYMK color spaces in that it is designed to match what our eye detects. The result is that the L-channel contains the non-color information, making it ideal for creating a BW image. In practice, at least from what I have found, there isn't a huge difference between the L-channel and a simple greyscale, but the L-channel does seem "crisper." For "j - lost in thought" I then increased the contrast in certain tonal ranges. (I use Corel PhotoPaint, but in PhotoShop this can be done with the Curves tool.) And I did other things, like blending in other channels which contain different amounts of texture. (Take a typical picture of a person and split it into the R-, G-, and B-channels and you'll see what I mean.) I probably used masks and such when combining different intermediate versions in order to modify Julie's face slightly without adding large gradients or other artifacts to the background wall. I started the post-processing of this image right after the photoshoot, it may have been the next day. I used the above techniques for the first time and was amazed and surprised that such a nice result popped out. Because i was just messing around at that point I wasn't very careful with intermediate files and, unfortunately, lost the full-size final version. The best I have now is a half-size final version about 1000x1000 pixels. I've tried a few times to go back to the original and recreate it, but I never get anything that looks as nice as this one. Oh well. I took this shot with my Nikon D40 with a Nikkor 55-200mm AF-S DX VR and: -- shutter = 1/60s -- aperature = f/5.6 -- ISO 720 -- focal length = 175mm (equivalent to 262 for 35mm)

Very nice work. She's very beautiful. I love that portrait too. BTW, you can use the 'Channel Mixer' and check 'Monochrome' to get BWized picture in Photoshop.
