I'm still experimenting so I don't have the final workflow nailed down yet Greg, but it's based on layering in your Ha as a Luminance layer on top of your RGB (or LRGB for that matter) with a one or more gradient maps as clipping masks (normal blend) on top. I'm preferring the Ha layer blend be luminance as opposed to lighten at this stage. I've created a few gradient maps based on
http://mintaka.sdsu.edu/GF/explain/o...rendering.html) - the result critically depends on setting the gradients up properly. Oh, and don't forget to add some Ha to the Red and Blue channels as normal before you start adding Ha. Add any (lots of?
) additional processing on top of that to taste!
