@colleen - does the "official" contour software have presets for dusk and night? if you, or anyone else, can post the settings (contrast, sharp, EV, etc) so i can duplicate it by hand... thanks...

the other way to switch the contour between day/night settings is to carry two micro-SD cards: one with daytime settings, one with nighttime settings. good luck labeling them, changing them, and not losing them . a neutral density filter may be the way to go, but so far i've been unable to get anything decent from that camera at night.
