- Take photographs in natural light. Otherwise, learn to use your camera's white balance feature.
- Use photo editing software, such as Picassa (which is free and easy to use) to post-process all photos. In Picassa, I usually use the 'I'm feeling lucky' button and almost always increase the 'fill light' to make my photos really shine. 'Crop' and 'straighten' are also nice features.
Since I don't own the world's best camera (I use a decent point-and-click with an optical zoom), I find that a couple minutes work before and after I take the photos makes a huge difference. I've taken a couple pictures to show the improvement these small steps can make:
Photo taken in fluorescent lighting with no white balance, no editing
Photo taken in fluorescent lighting with white balance adjusted, no editing
If you take photos in natural light or use white balance in fluorescent lighting, you can avoid using your camera's flash. Flash is useful at times, but can do funny things to the depth of the photo. I generally try to avoid flash, whenever possible, and opt for natural light or white balance.

I can't say enough about increasing the fill light. This feature livens up colors and takes away heaviness in a photo. Adding the right amount of fill light makes it appear as if the picture was taken on a beautiful sunny day, which is always a good thing.
ONE MORE PIECE OF ADVICE
One other thing I do when I take photos for my blog is to take lots of shots from different angles and placements. The more photos I take, the more likely it is that one will be spectacular. Plus, using a digital camera means that you can delete all of the files that aren't any good.
I hope these tips help you improve your photographs. It doesn't take that much extra time to rejuvinate a picture and the results are definitely worth it.
