Hi - this may be a dumb question ... I'm sure I'm missing something really obvious, but I just can't seem to find the answer in the users guide or anywhere else. I have a Canon 1000D. So far I have been mostly shooting in JPEG, but would like to start using RAW so as to have more control over the final image. To this end, I have tried shooting a few pictures in RAW format. However, when these files are imported into Aperture, they are there but they just show up as black. What do I need to do in order to be able to see and work with these images? Any help much appreciated. Many thanks.
