Lens cap black and flare level

[Derek]

@meleshkevich Thanks that makes sense.

@daniele you say elsewhere

@daniele

We treat the problem differently and raise our black-cap black level to something slightly positive. Then we do our image processing all the way to the final display rendering, without worrying about negative values. Then on the last step, we account for the black-cap black level.
This is a common workflow in VFX called pre-flare.

I’d be interested in learning more about how to do this in Nuke or Resolve. Are there any articles you can point to that cover this workflow in detail?
