A new D5100 owner here. Is there a way to set the color to "neutral," and the ISO to auto? In Auto mode, I can't set the color, and in P mode I can't seem to set the ISO to auto? I hope that I have over looked something. I don't like the saturation in Standard color mode, but I don't want to have to set the ISO each time before I use the camera. Thanks
In P-mode, to set Auto-ISO you go through the menus. Shooting Menu > ISO sensitivity settings.
There are quite a few more settings in the menus than in the Info display.
