...but when I download the files off my 5DII or view them on the camera through windows explorer, I'm only getting small jpegs. From what I can see in the camera manual, I've done everything right. When I go through the images on the camera the recorded size is shown as "RAW + [fine] S 1.47 MB". I took 111 shots, and the camera is showing space for 132 images remaining on an 8GB card, so that leads me to believe that the uncompressed images are on there somewhere, but I can't figure out how to get to them.
I was hoping that these shots could be used for 8x10 prints, but if all I can get are small jpegs that require sharpening and contrast, I fear the quality will not be good enough.
