I just shot a bunch of images on my 20D (RAW+JPEG L) I've downloaded them to my pc using my card reader and the camera/pc has given every raw image a cr2 extension. I have the RAW image installed in my copy of photoshop CS and if i choose to open a file i can select to open a raw image. I can't open CR2 files though. I've tried chaning the CR2 to RAW and at least then PS asks for the image size. However when i type in the sizes (2336x3504) PS says that the specified size is too large and the file wont open. The image size is correct since it's full size and not cropped. Can someone please tell me what I'm missing? probably something simple!!!
