As small point and shoot cameras with affordable lenses are used widely for candid photography, photographs may feature vignetting, distortion and over saturation of colors. Due to short reaction times, exposure or focus may be slightly off. Due to strobe flashes being obstructive to candid photography and incompatible with many compacts, pictures may show blurring or other technical faults. All these are usually accepted as features of candid photography, and often, part of what makes candid photography an art.
