Yes I always transfer to the HD before editing a copy of the original. I never work with the originals unless, like here, I'm taking pics of the living room to test. I opted for CHDK2EXIF to make a copy rather than overwrite. I currently don't have software that will open the .crw files directly, that's why the 17 flaming hoops. But this is workin for me. But at the end of the process I now have a .crw, a .dng and a pair of .jpgs for each image.
I don't know that I'll be using RAW for everything(although some do) but its nice to know I have the capability for those photo safaris.
Thanks again for your help. Now to fiddle with those motion detector and lightning scripts
