Hi There,
Following gaining a successful resolution to this issue using the 'Screen' mode of the Opacity function, I have now encountered a slightly different issue. Having layered multiple frames, I am experiencing an awful lot of what I think you might call 'noise'. The more I layer the frames of black, the more I lose the pure nice black colour of the night sky and it becomes lighter and more blurry and grey. Is there a color correction or other such function or technique that might eliminate that noise and maintain the clean black color?
Many thanks,
Jim, U.K.
