Vibrant Photo Manipulation by PSDlearning.com
“Using vibrant colors is the best way to make an image stand out, although getting the right balance is not always easy. Here we learn how to use lots of vibrant color to create a slightly abstract photo manipulation using pencils and fruit. We will learn how to use the pen tool effectively and also some freehand brushing which looks good.”
Nice Photoshop tutorial by PSDlearning.com which I just found this morning. They also have a lot of other interesting tutorials as well.
