Good morning people,

I'm off to work so this will be short.

To help with preview, my technique is to add an infinite light JUST FOR PREVIEWING. I set it to really bright 100 to 150 %. Before rendering, I turn it off with a simple shift-click on the light widget. This way I don't mess with my rendering lights so I don't have to put them back to normal before rendering. Also, I can quickly turn this light in any direction to help with previewing. Where it's pointing during render has no impact because it isn't used for rendering.

I'm sorry but I don't know how to do anything in PSP. And I don't even know how to do GC in Photoshop. Yes PS has light levels, curves, and color management but which of those is the easy way to do precisely the same math as (x to the 1/2.2 power) is unknown to me.

As to when you should add a light, it should be motivated by the real-world scenario you are simulating. Are you doing an indoor scene with windows? There should be an IBL, a point light in each window to simulate the incoming ambient light from the sky, a point light or spotlight for each lamp in the simulated room, plus one infinite for sunlight streaming into the room. Outdoor daylight? One IBL and one infinite. Moonlight? One IBL and one infinite.

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
