Hi all, I need some pointer to the right tools for doing noise reduction for my first time lapse try. I took about 300 frames of milky way, with 2000 iso and 15s SS with my GX7 + pana lecia 15mm. the images are alright, got enough detail to make out pretty obvious milky way and with some brushing I can get a pretty decent picture. But since I turned Long exposure NR off during shots, the noise in each frame is pretty bad, a lot of red pixels along the edge of the frame edge. I did some research on my own, and pretty much all the people are suggesting to do stacking for noise reduction, but all the tuts or posts I can find seems focus on stacking to get a perfect single frame out. I can't seem to find any information regarding how to get a so-called average hot spots map and apply them to all the frames in the time lapse. is it this something doable on raw or I have to export them to jpg and work form there? Also I probably want to do some local brushing in LR to give the milky way a more yellow/purplish looking, is there any tool I can just apply the brush to one frame and automated process across all frames as the milky way go across the sky? Thank you very much for the helps in advance!
