View Full Version : Infrared light rendering...?

There are photoshop filters that try to simulate UV or infrared film, but it's not very convincing, especially the infrared effect. It just seems to be something like a soft diffusion filter. So anyway, I was thinking of simulating infrared or UV light in a renderer, but I don't think I have ever encountered a preset of this kind before. Is there a renderer out there with such photographic presets? Can this be accomplished through Python scripting or do you have to get down and dirty with a shading language? I am not a coder by any means, but I have been thinking of dipping my fingers in it lately, so that would be an engaging exercise to say the least.

Are you after what they get with those cameras able to catch the heat levels and translate that into a picture like this:

Or the infrared found in consumer cameras nowadays giving this look?

It's more like the infrared film look, so the bottom one.

It always seems to make grass and leaves white like snow (http://images.google.com/images?hl=en&ie=UTF-8&q=infrared%20photography&sa=N&tab=wi&um=1)

Maybe you could do that just through your color choices.

It's not really that. There is the subtle soft lighting and glowing effect to infrared photography that is hard to replicate.

Either do it in the shaders - or fake it in post afterwards...

I second in-post. In 3D just doesnt make much sense to me.
