I am using Photoshop CS3 extended 10.0.1 on Mac Intel. I have made a layer of one photo that I want to blend into another. Last time I did this in the distant past, there were handles in the selected layer that I wanted to blend and I could grab and drag those handles to change the size of that layer in relation to the other. It was very simple. I have been at it for quite awhile now but those handles are not there and I can find no way to make them appear. I cannot change the size of one layer in relation to the other. Please help.
