Dev/Autodev mask?
Posted: Sat Aug 01, 2020 7:10 pm
Hi, Ivo
I'm currently wrestling with a Crescent Nebula shot, and minimizing all those stars after they have been stretched into visibility is difficult.
It occurs to me that rather than stretch the star field into full visibility and then deal with them downstream, a better approach might be to stretch them less in the first place. And yes, I did use an ROI on the crescent, and it did reduce stars a bit, but not nearly enough.
How about enabling masks in Dev/Autodev?
Like this...
Autodev->bin->wipe->Autodev
Generate star mask
Autodev or Dev again, minimal re-stretch on stars in mask
Invert Mask
Autodev or Dev again, ROI re-stretch (over a masked area) on nebulosity.
Thoughts?
