Thanks for that book reference!
Photography is also a subject that interests me.
I’m not really a practicing photographer but I do take some pictures sometimes for reference or texture purposes.
Light itself is something that fascinates me for some reason.
And especially where the possibility of merging real world lighting into CG lighting.
When I’m working with CG cameras I wonder what else could theoretically be possible with cg generated images.
Like would it be possible to add additional channels to an image that comes out of a render engine than just an alpha or depth channel.
Maybe something like an IR channel that you could generate from inside the cg cameras attributes.
Like having a camera that captures the image of the visible spectrum, and also the IR spectrum that you can edit to influence the visible spectrum of the final image.
That you can render to a seperate pass too.
It could not only allow for light control, it could also be used to more accurately simulate colors for explosion FX from simple bon fires to jet engines and even the formation of stars and space FX.
They use a similar technique to color the images that come from the hubble telescope.
What I’m talking about is a loose reversal of that in a way.
Except you generate a grayscale image of the heat information to simulate explosions and heat FX, it can also be represented with a multi-colored image to control the temperature of the illumination.
And maybe even a 3rd ultra-violet channel that could be used to control gamma dynamically.
Making the simulation of sun light much easier and more realistic.
I don’t know what’s actually possible with advanced render engines like Maxwell, Fry, I don’t even have V-Ray yet.
I use Cinema4D 10 with the built in Advanced Render module.
And it’s slow when doing GI, SSS and caustics.
So there’s no chance of lighting a scene with accuracy of lighting in mind.
I do what I can.
But it’s real easy to blow the image in the long run.
