One of our photographers lost his raw files from a photoshoot, but we still have the Capture One preview/proxy files (.CR2.cop) and I'm trying to find a way to extract image data from them to salvage the shoot.
I have read that they are JPGs, and I see evidence in the files (viewed with a hex editor) that they may be TIFFs – perhaps JPG-compressed TIFFs. Without success, I have tried (on copies):
- changing file extensions
- splicing and dicing blindly in the hex editor
- "recovering" with Photorec (may not have done it properly)
- opening the session in a fresh install of Capture One (nothing appears)
- opening the proxy files directly in Capture One (nothing happens)
Can anyone shed light on the format of these files and/or how to open/display them?
I do have a request in to Phase One support to see if they can convert them for us. I've had one reply indicating "Normally it is not possible to convert preview files to jpegs," but they are passing it up the chain to see if something can be done.
