I think I've found the solution. I was downloading photos from the camera with iPhoto, which didn't distort the colors. However, it didn't appear to properly convert them to a color space that gimp liked. When I download the photos from the camera with the Canon software, they don't need to be converted when I open them with gimp. They seem to be the correct colors now. Phew! Thanks for your help. All the questions got me moving in the right direction. -- Felicia
