Thanks to all for your thoughts. THe pic I am working on it attached. The problem I have is that the crosshairs for the guides end up right in his body when they are visible and are not of much use. I get them to move a bit, but it makes no sense. . . and I can not raise them to center them on his face.  The attachment is a render - you can see the foot is out of focus and that pleases me . . . but I want to blur the back ground a bit more. What would you do to improve this render? Thanks for discussing this with me and providng hints as I learn . . .
