I've just downloaded the CC subscription and I'm trying to edit a few photo into on of the sky at night.
Maths photos have a significant about of noise. When I go in and edit the photo how I want it and make the blacks nice and dark and reduce all the noise so the stars look nice and sharp in LR the photo looks awesome but once I export it the blacks are not as black and there is noise.
The quality doesn't look anywhere near as it does in LR.
Im editing a RAW to expert to jpeg. I can't figure it out.
Please refer the below related discussions.
Also, try and export in ProPhoto as well as Adobe RGB 1998 Or Calibrate your Monitor Color profile to default and check if that helps.
