Thanks for the comments, everyone!
Steph...I don't actually have "Photoshop" either. I use Corel Paint Shop Pro Photo X2. It's brand new software, just came out this year. It does everything that I could possibly ask for as far as photo enhancement goes, and has a built-in HDR merging feature. So far, I have not found anything I wanted to do that I haven't been able to do. And it only cost about $60, which is roughly 10% of the cost of Adobe Photoshop CS4. Awesome program, and even have improved workflow management and RAW file processing. Great program, IMO, at a very reasonable price...
If you ever want me to "touch up" any of your photos, just let me know. You take awesome pictures, and your jaw would literally hit the floor when you see what some very subtle and minor adjustments to contrast and sharpness can do for your pictures. No matter how good your camera is, there is always work to do "in the darkroom". No digital camera has the processing power of your computer, and ALL photos can use a bit of minor adjustments to improve the look. It's just a fact of photography in general. Even film cameras cannot get the "perfect picture" without a bunch of time in the darkroom, processing. It's just a lot easier in the digital darkroom...
