Flashes are critical for good nighttime pictures, and the three typical types available on game cameras are white flash, low glow and no glow. White light flashes are the typical flashes like the one on your personal camera. Very bright in total darkness, they often spook animals momentarily, but usually don't seem to run them completely out of the area. Low glow, or infrared, use a dim red glow when photographing at night. While they can shoot good photos, they will only produce black and white pictures when shooting in the dark. No glow, or black flash, doesn't emit any visible light, leaving animals with no clue anything is amiss. No glow will also only produce black and white photos at night. When considering flashes, also look for a camera with a longer flash range, since you'll get more quality night pictures with it than one with a shorter flash range.
