Question... so you have to export to to get to the .crw file, does that mean you have to re-import your altered images back into iPhoto?
I've been using Dr. Browns image processor to batch process my raw files and then outputting tiff or psd and importing those into iPhoto (and saving the original .crw of course)
Somehow that still seems easier than putting in raw, exporting and re-importing... but maybe I'm missing something. I've never actuall used iPhoto's export, I just open in pshop and then save as to get a new pic.
It seems strange that iPhoto doesn't hand off the actual .crw that would have been sweet.
