I know its super duper wols but I just learn it and wanna share it....
Cause I always wonder how come things start to appear greyish when its dark (just like those CCTV cameras).
Now I finally understand its due to the way the eye works.... We have those cones and rods.. Rod works well under low light condition but its neutral in colour (meaning it can only display white or shades of grey, no colour). Cones don't work well under low light thats why we need lights to see colour.....
OIC, now then I know....lol.... I never know we see things in black and white also.... Machiam old TV like that.
