I have read numerous posts about shooting in RAW and JPEG. I use PSE 8 to adjust. A member recommeded I shoot in RAW+JPEG. If I shoot in RAW+JPEG, should my D3000 make two files, one in JPEG and one in RAW? When I download to Nikon NX, the program that came with the camera, should I have two of each image? Should my Nikon suppled program be the first place I download photos to?
