Recently I took a picture of the milky way from inside a cave.
I've processed everything how I wanted and it looks great on the web but now I need to print a large version of it (610mm x 900mm). After going back into the file I noticed a ton of redish colour in the shadows of the image around the edge of the cave (as seen below)
I understand this is due to the high ISO and the camera, however, is there any way of limiting this in post processing?
I thought of going over it with a black brush at a low opacity but I'm afraid that at that size it'll look too obvious
