I am doing an assignment and I usually open up my photos through Windows Photo Viewer. However, I am unable to do that now because Window's won't support images that are in RAW file instead I have to convert them to JPEG's. I can't do that because the assignment requires that the photos are in RAW file. The reason I need to open up my photo's is because I need to crop and rotate some photos. What program can I use to support this?
