I've once watched a movie in which CIA agent went into a room just for a few seconds and on the next day he could recall every detail of that room, including what was on the monitors.
And I am wondering is there a way to improve my memory to this level?
I would also like to know if there are studied ways of accomplishing this.
There also is something that I remember reading few years ago about training visual memory:
"You go into a dark room with a page of text and a flash light, and every ~30 seconds you turn on and off the flash light very quickly and try to recall as much as you can. And you do this for ~20 minutes. After ~30 days of practice you should have much better visual memory."
What do you think about this method. Could it really work? And if so, could this ability disappear after some time without practice?
