Hi all,
I think I know the answer to this, but just need to be quite sure.
I want to know how to 100% confirm if DNG's that I have, have the original CR2 Canon RAW embedded in them?
I'm pretty sure I've always done this when converting to DNG, but want to be absolutely sure before I delete my CR2's forever.
I'll obviously need to do this in a scripted fashion.
Is the presence of the following good enough, or am I missing some better way to detect this?
Original Raw File Name : IMG_0013.CR2
Original Raw Image : (Binary data 30406314 bytes, use -b option to extract)
Thanks!
This definitely indicates that some data is stored for the RAW image. To be sure that the exact image is stored, I would try something like this:
exiftool -originalrawimage -b FILE.dng > out.cr2
diff out.cr2 original.cr2
I would feel much better to know that the image was stored properly and that I could retrieve it if I wanted. Just running a test like this on a few images would let me sleep better at night.

Thanks heaps for the Phil, and your awesome tool.
I may even just md5sum or similiar to what you've suggested.
I just needed to know for sure if that was the meta/header stuff I was to look for if the embed existed at all or not.
