Not being one to stick to the original plan, I sent these three in to iStockphoto for approval. To my happy surprise, 2 of 3 were approved. But #3 didn't quite meet their lighting requirements.
Looking over the image, I can see what they mean. It took a while in lightroom to really get that background white, and I ended up with her face and hair a little too bright in spots, and a little too dark in others. As a result, when I look at the image I feel a little too drawn to the chessboard, and not drawn enough to the beautiful model.
I reshot today, but couldn't get exactly perfect before said model got bored, below I'll show some of the attempts. You might also notice said model had frosting and crumbs on her face and the remains of a painted-on "unicorn pegasus" from Tuesday... The lesson: make sure your model takes a bath once in a while, and washes her face and brushes her hair before your photo shoot.
A little better, but I'll keep trying for a better expression... I do like the shallow depth-of-field shot of the chessboard though. I might see how they like these two at Fotolia, they seem a little more forgiving of my less-than-perfect backgrounds.
In the meantime, I'm loving Kelby Training! For a meager $20 a month, I'm watching hour after hour of training on general photography, Lightroom 2.0, and Photoshop CS4. Beats watching TV and learning nothing, but don't get me wrong- I haven't missed an American Idol episode yet.
