I'm trying to take indoor portrait pictures of babies with my Canon EOS Digital Rebel. I've been placing my subjects by window light instead of using the on-camera flash. It's worked out well through Spring and Summer, but now the early Winter light is here, and my last set of pics didn't turn out very well without the flash. Anyone use this camera and if so, what settings do you use to take indoor portrait shots? I don't have an external light for my camera, trying to make the photos work without one right now. Thanks!
