I recently encountered a problem that some of my photos of galaxy can't be outputted as preview's so I would like to ask if there is anyway that I can fix this. The output one looks "darker" and the "contrast" has decreased compares to the preview one. Please take a look:
Preview one in Lightroom (through printscreen)
Output (JPG, sRGB, at 8000kb max)
The output one seems revealing more "stars" (details) but the different in output and preview problem is bothering me so I would like to know if anyone could solve this problem. Thank you very much!
