Adobe is/was offering a cheaper CC version for photographers with PS & LR. Also, just as an FYI from a longtime Adobe/Macromedia (RIP Freehand) user, those of us paying for our own licenses always skipped versions as Adobe rarely updated enough items between releases to justify the expense. I'm still mad about the CC, but I've mellowed a bit as they are actually adding features and haven't raised the price (yet).
Yes, I've always skipped. I went from early versions to a student copy of 6.0 to CS2 to CS6. The newer additions are nice, but an experienced PS user can usually get the results he wants with the old tools. Maybe not major additions like liquify and puppet warp, but the bulk majority anyway.
I've warmed up to CC a bit, and I'm real tempted by that $10 monthly option, even though I just bought CS6 less than a year ago. But I'm having a really hard time convincing myself that it's a safe move to the cloud for Lightroom. It's one thing to not have the ability to use a particular editing program, but Lightroom is more than an editor, it's my entire file management system. All my edits, organizations, tags, albums, picks, etc. Without access to Lightroom that’s all gone. And Adobe is making no commitment what that access is going to cost you in the future. It might not be as concerning for full-time pros, but us part-timers and hobbyists don’t have as much solidarity in the system.
So let’s say 5 years from now something happens in my life and I'm no longer actively into photography. Family illness, work, family obligations, whatever. Again, for the non full-time pro, it’s much more of a possibility. Lets also say it's now $30 a month for access. $360/year is a decent chunk of change for something I don't use. It's no big deal to not have access to Photoshop. If I want to 'chop again, I sign up. But I no longer have access to my file system? The edits I've made? The catalog that I've spent the last 10 years or building will no longer be backwards compatible with CS4. The only way I can access all the work I’ve done is to keep paying Adobe. At that point I don't need new features, I'm fine with an old version, but I need something that can read my file system and my edits. All I have to speak for my photography the last 5 years are anything I exported, and folders and folders full of unedited, unorganized RAW images.
