Yeah it doesn't really matter, use your artistic license Maybe the budha model?

Outstanding contribution Godzilla. That's exactly what is needed in a manual.
It should make appetite for more and a few screenshots of the Blendigo panel just do not have the same appeal as your renders to exemplify the different settings.

Having a little bit of trouble locating a Utah Teapot model on the internet.... If a 3DS Max user would be so kind to export the teapot (Without a turbo-smooth modifier, just in primitive form) in .OBJ format and upload it in a .Zip archive, I would greatly appreciate it.

teapot!

Thanks soup!

I couldn't think of a way to implement a good use of aperture diffraction in the scene, is it ok if you use the previous one?

Godzilla you're awesome.

That monkey is freaky in the app. dif. images - I think it might be confusing even ("Aperture diffraction turns monkeys into deamons?!")
If angled the sun right couldn't you catch app. dif.? Or a glass teapot would most definitely diffract hardout.
Thanks for the images Godzilla, you da man x2

Updated with all new images from godzilla!

Looking a lot better!

Some captions still needs correction, though: in the clay render images and the aperture diffraction ones.
