Vignette and Colour Cast removal. How do I do that with HF3P?
I'd like to be able to remove some slight vignetting with a colour cast from a video. Apparently this is a common problem with a known solution. I just don't know which bits of HF3P to use to do it.
With a reference frame taken of a white surface the vignetting is visible.
Apparently, the idea is to subtract this from the original video image to get back to a normal(ish) original. But how do I go about this?
