This short demonstration was offered on zoom to my facebook group. It provides a technique for adding dynamic lighting to an element in Photoshop to bring down the light on one side of your element or drop it into deep shadows while at the same time revealing the highlights where you want the source light revealed. The beauty of this techique is that it uses gradient maps matched to both your background theme and your element so that the color changes are controllable and color matched to your image.
Additional discsssions at the end of the lighting demonstration offer additional tips on Photoshop techniques. Enjoy and keep on creating!!
