Photos are slightly brighter, though the original Go produced warmer images that felt more true to life. Still, the photos are charming in the way only a Polaroid photo can be. Contrast and color saturation levels are still low, but in a way that exudes the vintage, almost dreamy look of the photos taken with the Flip.
