It's funny, but the more I dig into digital photography and image manipulation, the more similarities and corollaries I see with digital audio processing. If anything, having never processed my own film, all I ever learned about photography many years ago stops being of much help...
I did "wet chemistry" black and white, mostly landscape, for about 30 years. I went digital and put the enlarger into storage a few years ago and I don't see it coming out and back into use any time soon. Photoshop, Lightroom and Bridge are the imaging equivalent of Pro Tools in that they're the 'industry standard'. Unlike Pro Tools they're also pretty much the best at what they do and while there are alternatives none are as capable as the Adobe products. And Adobe doesn't insist that, for the best results, you buy a specific, over-priced expensive camera from them to go with it.
There's a steep initial learning curve with Photoshop just as there is when moving from tape to a DAW (and I've never got my head around Lightroom, it doesn't work the way my mind does or something) but once you've got the basics down you wonder how you ever managed to do anything the old way.
Despite never owning the software, Adobe's rental scheme works out quite well if you use several of their applications or want the newest version as soon as it's released/is stable. Avoid the recently released Lightroom CC 2015 for a while though, it seems incredibly buggy at the moment. Lots of people reporting all kinds of problems, and it even crashes on launch in a fresh OS X installation on my MacBook Pro. Which isn't what you'd expect from a supposed leading software house's "professional" product.
And if you're into black and white/monochrome, the Topaz b/w plugin is both cheap and excellent.
