Hello, I am facing a problem with my X-T2. When shooting at night and when the shutter is half pressed I see the image on the screen and I expect the image I’ll get to be the same but when I go back and look at my shot I see the image is under exposed. I don’t know by how many stops but it’s definitely a lot darker than what I saw when I was taking the shot. I don’t understand it and it’s extremely frustrating. Any tip will be much appreciated. Thanks
