I think it depends on the photographer and what they need or want to use to finish the job. I think statements like “If you don’t use photoshop, you aren’t a pro” are silly.
But, this is coming from a hobbyist that doesn’t own photoshop and has an untouched free copy of PSE.
There are times when I kind of want to goof around and make funny or creative ideas come to light, and having PS would certainly make it easier, and other than someday wanting to try focus stacking and giving the Brenizer method a good go, I really don’t have much of an interest in PS. I doubt I will ever purchase it, or a creative cloud account (or whatever they call it).
