after i updated to a new lightroom, (or after i switched to a 5d mkII), importing files turned from cr2's to dng. i thought nothing about it as i thought it was some kind of new file either lr or the 5dmkii had.
after finish processing all my pictures and exporting them to a folder, i noticed they were all resized smaller!!! (i.e. 453 kb, and 720x480). is there a way i can convert dng back to cr2? or will the resized picture affect the way my clients print their photos? help!
