Well, I did use this camera at night for its ISO capabilities in the town of Québec. Below are some of the settings I have applied in Adobe Lightroom Classic to each photo. The only settings that may change between each photo is the white balance value.
I find, from the results below, that the Nikon D3s is still a great performer and a great camera to use in 2022. Though built, reliable and fairly cheap.
