>>3142623>I know that when im shooting at iso 6400 I have to use slow shutterspeed (1/30 - 1/80)What are you talking about?
-ISO determines the sensor's sensitivity. A higher number means more sensitivity.
-Shutter speed controls the duration of exposure, which affects exposure. (Longer exposure means more light, shorter exposure means less light.)
-Aperture controls the size of the opening in the lens that lets light through. (Smaller number means bigger hole, more light comes through. Bigger number means smaller hole meaning less light comes through.)
Go to your library and read a book about photography basics. Sounds like you've been misinformed by an idiot friend or an idiot blogger.
