Software to read 7D Raw files
I believe I read a couple threads where folks were complaining that Photoshop didn't read the 7D's raw files. Not sure what version, but some responses indicated that you had to use Digital Photo Professional or ACR I think.
I am using Photoshop CS4 and it does read the 7D's CR2 files. I'm not sure if CS4 has been updated for the 7D's profile, but RAW will open the files with a brightness of 50 and contrast of 25. This is the profile for the 30D and 40D so it might not have changed.
Though I share.
