I've used Apple's iPhoto since it's inception back in 2002 for processing all my family photos. It's pretty intuitive interface makes improving photos easier than cooking a gourmet dinner, with a lot less steps and ingredients.
With iPhoto 8, Apple has packed the digital darkroom software with all types of useful features, but at its core is the color adjustment tools that will help you improve you photos and even print them on your ink jet printer.
The attached screencast shows you how to improve your digital photos by using iPhotos easy slider tools. With iPhoto, you don't have worry about destroying your digital images as you work to improve them. Anything you do to your digital photos can be completely undone. In fact, the changes you make to your photos are not actually applied to the original digital file. That file remains untouched so that you can always convert back to it's original state .
Try out this tutorial using your own photos and iPhoto software. If you run into problems, feel free to leave me comments and I can help you out.
