I have been reading more about the custom curves function on Nikon's DSLRs and have this question: Are the custom curves applied as part of the exposure process or are they applied after exposure? I am just trying to understand if applying customs curves in camera to improve shadow detail will result in less shadow noise as oppose to when the curves are applied post-capture in Nikon Capture or other post-processing software to achieve the same effect. I understand that applying curves are applied on a log-scale in camera and linearly in the post-processing software. However, if the difference in applying the curves in camera or in post-processing is merely in the scale in which they are applied, then you won't get any noise improvement when shadow details are lifted. But if applying the custom curves in camera invovles changing the gain of the sensor amplifiers etc, then applying the curves in camera will definitely result in lower noise in the shadows. Can't figure out which is the case. Ideas anyone?
