I took photos of myself in just jeans and a tank top -- so nothing that can't be seen by others... but I had the same reaction unfortunately. I do intend to take pics again for comparison in hopes that, like
mdchick, I see enough of a difference to feel real good about the progress.
I've always been super critical of pictures of myself, so in hindsight it's not exactly the best method of positive motivation for someone like me. No matter what I would find something wrong!
So instead I use measurements to help determine my success.
