Same image imported into Lightroom Classic gets darker
In preparation for the April 2024 eclipse, I am photographing the sun with ND 5.0 solar filter, ISO 200, 500 mm, f/11, 1/1000 using a Nikon D750. I manually took three successive shots within one or two seconds of each other without changing any of the settings. On the Nikon screen they look the same, but when I import them into Lightroom Classic the second and third shots appear much darker. Can anybody explain or resolve this?
