I do a lot of timelpase photography and use Adobe software in my post workflow. I would like to master the process of using black images to reduce the digital noise of astral timelapses taken at 3200iso. I work in a RAW workflow then output to DPX image sequesnce.
Here is a link to forum topic I started on a timelapse forum with a similar query. I am just wondering if there is a way to do this with Ae in the RAW workflow or something similar. Instead of using other software. Maybe a Ps batch process?
If you want to investigate a way to do it in AE, you could look at Color Finesse. It might treat crushing those blacks more gently than anything else.
AE has a denoising effect, but I'd be afraid it would de-noise the stars right off the image.
I will look in to but I usually use resolve for colour correcting, not sure if this will help me take nosie out in the composition. I think there is a standard way for de-noising clips with black images taken under the same parameters specific to astral photography. I'm sure I'll find an answer soon.
