This whale was sculpted in sculptris. I had in mind to retopologize this guy in blender some day.
I rendered the sculpted image out and did some drawing + compositing in Photoshop.
(On this image i was playing around some more with RGB-Curves).
---------------------------------------
For the DOF effekt in PS, i duplicated the whole layer of the final image so that you have two.
[to the top layer]
1. use the "gaussian blur effect".
2. Then u need to add a mask. Take a pencil with soft edges, adjust the opacity a bit lower and begin to draw a simple black dot on the mask where you want the sharpness of the picture higher.
Thats it.
You can play around with the both colors black and white to optimize your mask.
can i have this 3d?
