Ban on Raw in Stock photography discussion and contributor experience Posted November 19, 2015 So how can they tell between a LR export from RAW and a LR export from jpeg- surely the software flag will be the same. My understanding from the comments below the story is that the EXIF gives the game away. But I don't know if it's possible to edit that. Richard. Yeah it's possible. Whenever I buy a new camera that isn't on C1's list, I change the camera details in Raw files with an exif editor so I can process them (provided its the same make of camera, fuji pro - x-t1). Some apps allow you to do bulk routines for this if you have large volumes.
