Hi Chris,
I think I have finally figured out how to use the stretching in the output pic once its stacked in DSS.
What I do is adjust the black point slider on each RGB channel and bring it to the right until the channel widens and then "clips" where a SPIKE appears on the left of that channel. THEN, I slide it left one notch to remove the clip spike. This leaves the channel WIDE and stretched out. Repeat for the other two channels, trying to make EACH channel the same shape. Then I adjust the middle slider (grey point) so they three channels line up with each other.
Moving to the luminance page, I adjust the midtone sliders so the curve matches my attached pic and is placed over the three channels as shown.
Then I adjust the saturation to say 15-20% depending on taste.
Hit apply and whammo, a fairly nicely stretched image ready to slot into nebulosity or photoshop ready to be touched up.
Give this a go and see if it helps. It has seemed to work on my Atik photos as well as my DSLR shots (like the one attached), so I might be on to something.....
I use DSS beta 3.3.3
Cheers
Chris
