Greg, I might have made the dust look blacker than needed, was trying to maximise the dramatic feel. With more data I might have revealed more detail. Lord knows my crap guiding right now did a good job of smearing it!
Camera is a very early A7s, probably a rare astro collectors item now! They will pry the original firmware from my cold, dead hands. Yes it's modded per my sig. And I used PI's own green removal tool multiple times. Always need to keep repeatedly using it after colour adjustments.
