Hi,

there may be a more technical solution, but you could simply use desaturated textures and non-coloured lights. It's not a physically accurate solution though, as obviously real world black and white photography still captures objects which have colour.

I think you were better of doing it in post tbh,

cheers

You can use the photographic exposure lens shader, it has a saturation attribute.

It's in the "Lens" section of the Mental Ray nodes. Pop open Hypershade, can't miss it.

put it in the lenses shader slot under mental ray in the camera attributes.

From a readers' Q and A column in TV GUIDE: "If we get involved in a nuclear war, would the electromagnetic pulses from exploding bombs damage my videotapes?"

Sorry for hijacking the thread but can someone explain what the top attribute "cm 2 factor" does in this lens shader?

This is analogous to the Gain parameter of the mia_exposure_simple shader."
