You see this effect even more plainly if you apply a curve using the 'Curves' panel in Nikon Capture editor: the results are not the same as if you'd applied the curve in-camera. I'd assumed this was down to the fact that the camera had already applied the Normal (or whatever) curve and you were working 'on top of' the changes that had made to your data - whereas when you use the custom curve option in the camera you're affecting the translation from the CCD's linear space to the finished image.

Whatever: the in-camera custom curve is a very useful option if you want the camera to produce immediately usable results in the style of the compact digitals.
