And if you chose to use 3ds Max's exposure control then you could adjust the exposure of the camera in order to make the image the correct level of brightness. However, if you use 3ds Max's exposure control you're also succumbing to a destructive tone mapping effect that's being applied at render time. And you cannot remove that tone mapping in post. There really is no easy way to save out a raw image that's been exposure controlled and white balanced. If you're using another renderer other than Arnold then your best option is probably to multiply all of the light intensities by some value. Increasing or decreasing the overall amount of illumination is effectively the same as opening or closing the camera iris. There's not an easy solution for the white balancing…
