Play with Color
Don't be afraid to experiment with colors and by that I don't mean that you have to emulate Andy Warhol. Image editing programs put a lot of power in your hands. You can make the leaves purple, change the entire photo to black and white, add a sepia effect - almost anything you want. A good photo editing program will have automatic color balance options to adjust color defects in your pictures.
If you've taken a photo in a wrong orientation, it's easily corrected with little loss in quality by using a rotate tool. You'll also want to do some cropping of your photo to remove cluttered surroundings that draw attention away from your subject. For example, I find cropping very useful if my subject is occupying only the middle portion of the photograph. Cut away the two sides of the picture and you have a much more professional look.
If you're taking photos of people, chances are you may have taken a photo with red-eye problems. This is easily removed with image editing software. In Paint Shop Pro, select the Red-Eye Removal tool in the menu and voila, the program does all the work for you. In Ulead PhotoImpact, there's an equivalent tool called Remove Red Eye in the Tool Panel.

You may have also ignored them as being yet another degree of complexity that you don’t need to know about. Alternatively, you may have seen people on the Internet earnestly discussing colour temperature and swearing by all sorts of essential products that will guarantee perfect results, if you remortgage your house this one last time. And ignored it as another expense that you can probably do without. Well that thing you’re ignoring is one of the most powerful ways of making your photos convey the scene you wanted to capture:
