how the hell do they do this:

how can you adjust lights after the image is rendered?
is this some sort of database driven image creation?

I know nothing about rendering but i have an idea. During one render, they just save all the rays from one light to one "layer" or "buffer" or "whadayacallit". So each light has a layer which are saved in an HDR format to keep all the information. The layers can then be blended after.

So lets apply it to Indigo

lets say one .igi image file could have 4 light source layers since the scene has for example a sky, a sun, a meshlight and a rectangle light. You load the .igi in Ono's Violet Tonemapper and adjust the lights.

I think there was a program someone made some time ago on this forum. If you rendered your scene once for each light (as opposed to all lights at once in multilight) you could blend the .png's in the program...

Anyway, am i right Ono? or am i a n00b trying to sound like a pro? lol

EDIT: i found the thread, the program is Yellow by Zuegs

looks like with yellow you have to render multiple passes for lights
and than you blend the result together.

i am not sure if that is the way maxwell is going ...

You could do this with every renderer - you just have to render it as often as
you have lights in the scene (each render with a different light on).
Afterwards mix them with "screen" as blend-modus. If you have 4 lights you
need 4 renders/layers to achieve this.
The key is to store all the layers in one file so you don't have to render it 4 times.
