Using the same objects I created, I test the subjects for the Depth of Field (DOF) in Maya (it depends on the renderer).  It’s a nice tool for a photo-realitistic-effect you can create, where the only real camera can have this kind of visual effect, let’s say a bokeh effect.

Here’s my samples…

Strawberry with a wooden plane texture

Lamp test: Some of the 3d models from the web can be use freely (chair, lamp, and table) for your subject–personal or commercial–but don’t sell the models.
