Greetings, I'm a decent amateur photographer. I shoot with a Nikon, and generally thought I have a pretty solid understanding of how exposures work (ISO vs Shutter speed vs Aperature). I would always shoot with ISO at 100 for sunrise and sunset. With my Nikon, I've never had any issues . Shooting on the phantom drone, however, has been quite difficult. Many of my photos, while shot at ISO 100, have insane amounts of what I assume is noise in the shadows. I've uploaded a sample JPG here. I under exposed the photo slightly when I took it, because previous experience with my DSLR has shown I can easily increase it in LR, without risk of blowing out any color. Here, slightly increasing the exposure just destroys the blacks with noise, and I don't see why. I don't know if there is an issue with my camera, or I'm just missing out on something else.
