Re: D610 long-exposure noise

I'm really surprised to see this kind of noise from the D610 sensor.
Do you have enabled Long Exposure Noise Reduction (LENR)? Thist kind of NR substracts an extra dark frame right after the first picture is taken. In fact the camera makes a second equally long exposure with the shutter closed. So making a long exposure of 2 minutes takes 4 minuter including the dark frame substraction process.

Long exposure noise reduction with dark frame substraction maps the sensor noise out of the image for a substantial quantity. It is good explained here: http://en.wikipedia.org/wiki/Dark-frame_subtraction
