Hi all. I have a rather long winded question about removing the stains from this image. Probably because I don't know the correct terminology, so please bear with me while I clarify what I'm trying to ask.
Ok, so a computer doesn't "see color" per se. Each pixel is displayed based on various "data bits" that have been assigned to it. These "data bits" are what the various tools and plugins manipulate to alter what is displayed on any given selection on screen.
Now, and as I know there a lot of folks way smarter and learned about Gimp than I, so surely it's been thought of and solved already, I just don't know how to do it, is my question.
In this image, I want to select a small area of the sky, adjacent to an area of the sky that is stained. Store all the various "data bits" that define that selection.
Then, select an area of the sky that is in the stained area and store all of those defining "data bits".
We know the stained area is supposed to have all the attributes of the unstained area. It follows then, that whatever "data bits" from the stained selection differ from the "data bits" in the unstained selection represent the stain on the entire image. ( Assuming the stain itself is uniform ).
Surely there is a way in Gimp to compare the two selections, determine what those "stain bits" are, and remove the "stain bits" from the entire stained area.
Yes? No? Am I understanding the procedure wrongly?
