Auto gamma (C plugin - x64)
This filter calculates gamma values to manage the brightness and contrast of a whole video based on the range set by parameters "a" and "b", where lower "b" values output a brighter image.
There is also a parameter to apply a gamma transform first if you feel the image is under/overexposed and one to ensure that it can display the original pixel if it's brighter so no dark details are lost. There is accurate xy colorimetry and transfer functions for 11 colour spaces as of now, and more could be easily added. The filter here. See the wiki for more detail.
