In my day job, I'm a graphic designer at a local printing company. When it comes to Adobe Illustrator or Photoshop needs, the job in question always comes to me. Recently, I've really been focusing my energies on video production outside of work. I'm a New Media major with a focus in video so that's Really become my passion. I've even managed to parlay my video skills into a regular part of my job, so I'm a pretty happy guy.
Something has occurred to be as I've really been digging into Adobe After Effects over the last couple of weeks. Photoshop is often used in conjunction with AE, especially when you're talking about a composite. It just seems natural that even a casual user of AE has at least a working knowledge of Photoshop. The reverse is hardly ever true.
Photographers and digital artists generally focus purely on Photoshop and never come close to AE. It's not surprising at all. Heck, until a little over a year ago, I had no idea what AE was for. Now that I've had that time to play with it, scour every book I can find on it and watch every tutorial that I can... Wow. AE is extremely powerful, and not just in regards to video. I think of just little things like lens flairs, keyed footage of fire or explosions, the fun text manipulators... Those could be a real boon to someone creating something in Photoshop.
I guess my point is, if you're a Photoshop user and don't use AE, give it a try. I don't think you'll regret it. I know I don't.
