				I've seen this scene around other forums for some time and thought it should have a Kray version of it 
http://homepage.mac.com/janoverust/LW_t ... ring3.html
C&C are welcome and expected.
Something funny has happened with the time shown though. It's a second try (the first ran 10 hours or so) using 'both'. It went for an hour and a half or so but it shows negative time!

				Try to amplify gamma/exposure or photonmultiplier a bit since it's rather dark. Also try to use less bounces so the room dont get all blue from the environment  or add gammacorrection to the hdri to make it less intense coloured.
Other than that it's a nice image, thanx for sharing.

				Not much of a secret 

 I just rendered it with irradiancecaching off to get that fprime/maxwell look.

				Beuatiful as usual Silver! Gotta love that grainy look... Do the render times shoot up when turning off the irradiance caching?

				It depends of how strong indirect light you use and what AA you use. As a test try to turn irradiance caching off, set FG min100 max0, turn on undersampling 16-64 and activate fullscreen AA grid3 + Pixelfilter "cone" 1.5. If you think it gets to blurry/soft change pixelfilter "cone" to 1.0 or 0.5 depending of taste. if you want less grain turn up min FG and/or increase AA.

				Hi my version of classroom
this is speed setup
I must fix :
DoF, Area on ceiling, many textures, add backgrund, sun.
But nice redner light on the windows (no strong lights!)

				Very nice work but where does the light come from?

				All lamp off.
Only Gi from windows (Area) and sun (Area)

				Very nice Johny, but I think that your DoF is causing a scale issue. I'd try a higher value for the F-Stop, because small values cause it to look like the scene is smaller (model size, actually). Other than that, you got some nice lighting going on in there. I'm looking forward to seeing the update. Good stuff as usual

				Minor update in my first image. Higher multiplier used, and adjusted a bit exposure and gamma. Still need to work on the lighting some.

Yep I now (read my posts 

)
Big DoF is good for closeup not viz.
I use in scene 9 Area Lights, only Area.... Render too long but quality is very good.
