[QUOTE="ΜΑΝΩΛΗΣ ΚΑΣΤΡΟΥΝΗΣ, post: 108819, member: 7"] [FONT=Arial]The result deserves a closer look. It is easier to do so with the "worst" image:[/FONT] [FONT=Arial]We see that there are twice as many images at 100 Hz, as the smaller gap between two consecutive images shows. However, even if our eyes perceive a lower afterglow, or none at all, there are still ghost images behind the main one, even in the "best" picture at 100 Hz. Even more surprising, the brightness of persistent images at 100 Hz is a bit stronger than at 50 Hz.
