I have an interior scene with VRaySun and VRaySky and some Skyportals, I use a standard camera but with VRay Exposure Control in the Environment Dialogue and I render either with Gamma in the Color Mapping rollout set to 1.0 or 2.2 with the Don't affect colors (adaption only) option ticked.
When I add VRayLights to the scene to represent light bulbs they hardly add anything to the overall illumination. I set the Intensity Unit to Luminous power (lm) and test values between 1000 to 3000 lm, from what I gathered from a lamp/light reseller website that's round about what a 100W light bulb has, around 1000lm. But as I said, they hardly brighten the scene at all. The Colour Temperatur I set to round about 2700K, what gives it a yellowish tint. Is this due to that the exposure is set to work for the VRaySun?
If you want to brighten a particular part of the image, how would you do that, since the VRayLigts doesn't do much unless I set the lumen to like 50000 or so, but then it looks very strange for it is much brighter closer to the source and falls of vary rapidly; which I guess is due to the Inverse square law. Brighten it up in post? Or use "light cards" (not sure what it's it called) to bounce in extra lights, like photographers do?
