Just for fun, and because I feel it will com in handy in future on a personal level, I've enrolled on a course in using Adobe Photoshop.

I've been using photoshop for some really basic stuff for a year or two now, but after completion of this course, I should be at east highly competant with the application.

What I was wondering, is what commercial uses are there for a person skilled in photoshopping?

I mean, there's it's usage for web design, but at the moment I've lost my creative spark when it comes to designing wepage layout and look (quite annoying when you have a grand total of three web projects to complete, maybe four. Even more so when you're doing two of them for free for other people and it's stressing you out!)

Other than that, are there any other commercial uses for it where I would be able to put such a skill to some manner of money making use (even on a small scale)? Or am I going to aquire this skill and only ever use it for myself and my CV?

Theres always the chance to create banners and ads for big paying companys. But thats kindof like web pages and the repetitiveness will make it very boring after a while.
