Join Donovan Keith for an in-depth discussion in this video Preventing over- or underexposure with color mapping, part of Production Rendering Techniques in Cinema 4D.
Exposure is a product of the relationship between the number, intensity, and proximity…of lights to your subject, as well as the material properties of that subject in your…various camera settings, it's a lot.…Color Mapping works like an intelligent auto exposure for your scene, ensuring that your…blacks are black, your whites are white, and there is a good mix of values in between.…Let's take a look at a render of this simple scene, it's when we are probably familiar with by now.…What I've done is I've really cranked up the brightness of the sky outside, and what we…see is that our scene is, in a word, overexposed.…
The white regions are very white, in fact, overly so to the point that we are losing detail in our object.…The black areas are even quite bright.…Now I could go in there and start tweaking all of my brightness settings for my sky,…I could play around with the closeness of various objects and tweak my GI settings.…But perhaps a simpler solution would be to use Color Mapping, and this is a rather extreme…
