Tonight we're working with shadows - I have two tutorials for you!
The first tut is basic information about how shadows work. It will show you how to adjust your shadows in both PS and PSE to fine tune the look some. http://www.scrappersworkshop.com/hosted/tutorials/SHADOWSbasic.pdf
The second tut has two techniques to help you alter the shadows manually for a more realistic look. http://www.scrappersworkshop.com/hosted/tutorials/SHADOWsReal.pdf
Enjoy! And don't forget to post in the gallery and tell us how you did!
