I'm running Photo Mechanic 4.6.6 on Mac OS X 10.6.7.
After doing some research in the forum on how to setup Photo Mechanic to mark changes in the XMP files and leave RAW files unmodified, I found notes pointing to the Preferences -> Files -> "Allow RAW files (non DNG) to be modified for metadata and image preferences updates" switch. After unchecking it, the ratings I've done in Photo Mechanic only altered the XMP file as expected. I'm assuming this means that PM won't make changes to the RAW files at all, but would like to verify. So, my question:
Does having the "Allow RAW files (non DNG) to be modified..." flag in an unchecked state mean that Photo Mechanic will never alter RAW (non DNG) files, or are there operations that might still change them?
Thanks,
