Thanks for the feedback Marc. I'll have a look at it.

Not sure if it's a result of the debayer process
you might also want to save it in a format that has lower compression to avoid compression artifacts
I don't understand this comment at all. It's not a colour camera so debayering is irrelevant and I don't see any mesh pattern. Also it's saved at Jpeg grade 11 which is not very compressed.
