Thank's again scott. I do understand what you did suggest, I have just not had the time to try it yet ;) I also tried the Alpha trick in one of the first renders and (the second one in the previus tread). Getting the result I got in that picture was however not an automatic Photoshop process. The Z buffer only hold depth information and not really out of focus information(would be greate with a focus channel). This means that the sharpest part in a blurred picture will allways be the closest part witch might not be what you want as when I did the Dino. By playing with the curves or maybe by doing a by color selection in the z buffer and then invert it, it might be possible to use the z buffer so focus appear in the correct part of the image and by doing so even be able to use it for an animation. In my image i did it by composing togeter a blurred image and a sharp one while by hand deleting parts of the sharp so that the blurred one shows trough. If I get some time over I will try to lower the bump setting and maybe play some more with the z buffer.
