Image quality at 2 s exposure and various settings of Noise filter and Noise reduction
The camera has two image noise adjustments, Noise Filter that reduces the noise in every picture and Noise Reduction that suppresses the hot pixels at long exposure times. I didn't use the Noise Filter, because while the noise is reduced, it makes the image very soft. However, at long exposure times, the Noise Reduction function performs very well, eliminating hot pixels.

2 second exposure time. The warm tint is very obvious.
