Jeez! Like many here, I read that article and at first thought "is this guy insecure or just trying to appeal to hack photogs?" On a second reading (well, a skim) I think the author isn't going to lose any work from low prices or freebies but is using his position as a pulpit to decry and lament the old "we've lost the good ole' days!" (Hey, these days that kind of post gets
lots of web traffic - look at us discussing it!)
I was a pro fashion and product retoucher for 15 years, entirely digital. The digital part is key, because at first I worked on dedicate, half-million dollar(!) Quantel and Shima Seiki "digital paint computers, and you had to be a pro to even touch them. Ah, but then Photoshop v2.5 came out and really democratized *the tools* for retouching!
Oddly, I never worried that someone with a $3000 Mac and Photoshop could take work from me, even as things like the clone tool and layers started really changing the retouching game. I was good at what I did, and high-end fashion and advertising work demand more than a straight photo with some levels adjustment, no matter how good the shooter (and crew) is. Plus the deadlines will kill almost anyone who doesn't eat coffee beans and have a wacom stylus grafted to their hand!
Today I have a relatively relaxed job in software design (ahhh), but I can still photochop with the best of 'em. I know a few very skilled retouchers who are kept quite busy, but the line between "post-processing" and "retouching" has blurred enough that the simple stuff can be handled by anyone with some basic PS skills and a course or two from Lynda.com. Today you need to be
really good (and dedicated) to distinguish yourself as a pro retoucher,
and make a living at it. That's good, IMHO. Bad retouching bugs me (see
Photoshop Disasters).
That said, I do "retouch for free" all the time for my own photos and my family's old scans. We wouldn't even think to hire someone to do this stuff! Now when it comes to my wedding or an event where I want great photos, I find and hire a professional photographer (no matter how much camera gear I have) and tell them "do your post-processing, but don't spend much time retouching extensively - it isn't worth the grief I'll give you if you do a mediocre job."
