cr2hdr.exe question

[EWP]

I normally process a large number of CR2 files which are a combination of Dual-ISO and standard format images.  Is there an option, or perhaps a way to code cr2hdr to do a quick Dual-ISO test and exit if the image is not Dual ISO?

Currently it consumes a lot of time to make that determination before it errors out.

You can add a custom file prefix in camera for Dual-ISO images (there is an option to do that in Dual-ISO parameters), and apply cr2hdr.exe only to files with that custom file prefix.

Sounds like a plan!  I'm glad I asked.  There are usually many ways to skin the cat!
