Thanks Kmot. I use Photoshop for some things like enhancing the contrast and brightness but use a program called SnagIt for the shadowing, lettering, and arrows. SnagIt a real good program, but not as robust as Photoshop, nor as expensive, but I use it for a lot of things. I can capture pictures and video on the screen, etc. Download a free trial here: http://www.techsmith.com/download/trials.asp and the cost is about $40.

I have seen the covering vidoes here on RCU and they help a lot, but I guess it's just practice that will help me improve. Don't let that scare you so finish what you are building and send us pictures!
