Selecting DSO
« on: 2013 April 04 07:37:55 »
Am still learning the basic and trying to find out if in PI you can somehow select a DSO, exclude it and then operate on the gradients. 

What Photoshop can do for me is to select the galaxy, then deselect it to get the gradient outside the galaxy, then I can fix the gradient with Gradient Exterminator without touching the galaxy.  If I could do that in PI, I would be set to use DBE in PI.  As is I find DBE screws up the edges of the DSO.

Just don't put samples on the DSO. You can use few samples, but locat them on true background areas.

Yes, I tried the autoselect feature today and saw this is what it did.  The results are better, but have severely light poluted skys. 

I am also trying to learn the ACDNR tool.
