[QUOTE="spb_stan, post: 641536, member: 43545"] Why are you pixel peeping and underexposing 2 stops and expecting low pixel level noise? Maybe I am missing something but is does not make sense to me. A D610 will have wider DR than your friend's Canon. But you need to use it correctly for best signal to noise ratio. What was the reason for under exposing? That added 2 stops of noise. Expose to the right on the histogram and see just how good your camera is. I boosted the lower ISO images in Photoshop which should have boosted noise also and they are rather clean. View at normal distance and size they are spotless. How to get low noise in low light? Noise in low light is natural, our eyes certainly suffer with detail loss and color noise/loss, when viewing dim scenes. The reason is noise is random and light at low levels isn't because the constant noise it not as far below a low light level. More light in the presence of steady noise means the mid level light is far above the noise level. Cameras can't invent signal to noise ratio increases of low light scenes.
