ABSTRACT
I have heard one explanation that purports that the blanking time of a mechanical shutter is preferable for it lets our brain rest between the showing of each frame of image. My reply is to ask – if I blink 24 times a second will I feel less tired? Of course not. What nonsense this idea must be! If it were so I am confident God would have given me that facility. Here’s to flicker-free projection, I say.
