To give some insight into my dilemma. I made multiple copies of the image named “original” and then proceeded to use the bandpass filter to create layers with specific “bands” of information from the original image. I have all of the “bands” needed to make the original image, however, I can’t seem to compose them back together accurately.
I was told to try gimp’s grain merge a go, but as you can see in the file, it does not look like the original.
How should I approach solving it?
