Re: Black Level Without Optical Black Pixels

That's great work Jack.
It's always good to get another set of eyes on something.
And any raw files I have or can produce are always available to people such as yourself.

Black Level can be a problem. It certainly is helpful when Optiocal Black (OB) is available.

For my PDR measurements I only use whatever values are in the metadata (Exif).
Since I operate further away from read noise than DxOMark I suspect PDR is less affected by variations between the metadata and true levels.

(I use entirely different data to estimate read noise as opposed to PDR.)
