Now make a left double mouse click on the blue bar of the new layer. You will enable a window (layer style panel) with really great tools (try them, they are really interesting). Choose "OUTER glow" and change the yellow glow color to white. Now select the size slider and move it to the right side. Now you have a very nice glow effect on the teapot.
Another very interesting effect that you can create on a image is a Depth of field effect (DOF). In this way you can simulate a sharp focus point on the teapot. The part of the object which is far away will be a bit blurred (like in photography).

First of all we must fuse the background image (original rendering) with the glow effect layer. Just go to "layer" and select "flatten image" (image 15).



Now make a right mouse click on the layer and choose "duplicate layer" (image 16)
