i have been using Lightroom for a while now and really like it but the other day i tried the photoshop and the adobe RAW, which i thought was great
but can i just confirm, that i have understood correctly
with lightroom, you edit the RAW and can go back and change any settings when ever you like and re-edit the RAW file
with photoshop RAW, once you edit the raw file and hit "open image" and it opens in photoshop, you cannot go back and re-edit the RAW again ?
unless you start over again ofcourse
