I currently use Lightroom (OK, not too well) and am trying to learn Photoshop. My understanding is that if you do work in Photoshop on a RAW file, you permanently change the file. Firstly, is this correct? and second, does this mean you should create a copy of the original and work on the copy so you don't "corrupt" the original??
Thanks!
The RAW file itself is never altered.
