So. The bestest person in the whole wide world bestowed a copy of Photoshop Creative Studio 8 upon me. I could very well lose an entire weekend to this program, but so far I've just been playing around with all the various photo filters.
To wit, this before and after example of a sunset photo I took on 12/31/2004 (click the photo for a bigger version):

AFTER
Basically, I tweaked the saturation, contrast, applied a warming filter and a shadow/highlight filter, etc.
Oh, and today I bought a Canon G6.
