I've attached the following image which is used as a navigation background. When you look at the sample, you will notice that the bar is in two different levels. It starts on the left side being shorter, but takes up the full height about half way to the right side. I can use the Photoshop rectangle tool to draw a shape then add a bevel effect to recreate this about 75% of the way, but I don't know how to draw the transition between the two different heights. I'd like to ultimately get this shape on it's own layer so I can change the color as needed. Right now, I'd like to learn how to draw this shape so I can apply different colors and effects on it. Like silver for example.
