Why is there light in the scene where the sun has been turned off and there are no lights? In the last render, is this how you simulate DOF in postwork? I'm just trying to see if I've got the technique down right. Of course, all these renders are heavily dependant upon what settings are used. These were all done using all the optic settings but no premium settings.

On the attempted radiosity simulation (lower left)... Have you tried rendering on Premium, with blurred reflections? Looks to me like you need to turn up the reflectivity on both the sphere and the ground. This is one of the better methods of radiosity simulation, in my opinion. It has its quirks, however... like reflecting things you don't want it to and too clearly for instance. Hope this helps you out a bit...

you can controll the blurryness of the reflection with the specular halo.

In the one with the sunlight off it's lit by the skydome color (in the skylab below the sun/moon shadows slider). I've been confused by that one too ;) If you want that light to go away set the skydome color to black.

With the bottom left one, you can fake light bounce by puting a light under the plain and turning off "cast shadows". This also is more easy to play with and get best result...;)

mjhatch-- I disagree. No matter how precise your light placement is, you will always have either lighting where you don't want it or the shadows won't look realistic. In the above image you can see the results of reflective Radiosity. Personally I prefer this quite a bit to radial lights. Each to his (or her) own, I suppose. =)
