colored photo filter with gamma correction and combined soft-light over image layer

permalink

Hello,

I am a photographer myself.

I am seeking a solution to add a one colored photo filter (eg. #FFFFFF) with
gamma and density adjustable and without destroying luminance with
hard/soft-light compositors enabled over an image layer.

Is GEGL able to do this?

How much effort it would need to take to program this (eg. funds, etc)?

af

I do not understand what you are asking for, it also does not sound
like something that would be complicated to implement if it was
explained in an understandable manner. It kind of sounds like
something that should be implemented as a meta-op, using a combination
of existing operations.

Are you talking about emulation of orange/yellow/light-blue etc. color
filters used on top of lenses to add warmth or make the look colder or
make everything sepia?
