Please attach your attempted pipeline. We have limited “free” time to create pipelines from scratch, but are happy to give help and advice. What exactly are you having trouble with?
A couple other pointers:
(1) Avoid JPGs if possible. They are lossy formats which can create artifacts. (PNGs are a good choice, though TIFs are more standard)
(2) Not as important, but you can save processing save time and space by saving grayscale images.
