Time Lapse

Time-lapse photography is a  valuable photographic technique for accelerating scientific processes that would otherwise be too slow to maintain student interest.  Most phones cameras record at 30 frames/second, which for normal daily activities creates a smooth image

Frame-rate - Negative After Images - Negative afterimages are caused when the  black & white photo receptors (rods) and  color photo-receptors (cones), adapt to overstimulation and lose sensitivity.  Photoreceptors that are constantly exposed to the same stimulus exhaust their supply of photopigment, resulting in a decrease signal to the brain. This phenomenon can be seen when moving from a bright environment to a dim one, like walking indoors on a bright day.
