ev 0 to ev 1 is 1 stop of light, ev 0 to ev 2 is 2 stop of light

1 stop of light = iso 100 to 200, f2.8 to f4, 1/30 to 1/60

iso,shutter speed and aperture got effect each other

after u read goldfries link below if still understand can ask here again

if u see ur main subject dark, then increase ur ev lah....if increase 1 ev not enough, then 2 loh

kinda hard to explain here, u need to tryout urself

actually by increasing 1 ev, if u using av mode aka aperture mode, then the camera will set ur shutter speed slower by half or iso speed double since u are controlling ur aperture

google for better explanation

Hahaha...

Anyways EV is there because of how the camera evaluates exposure. Matrix mode or rather can be called auto mode is easily tricked by bright light sources. So let's say when you shoot in Aperture mode and it is dark. Only thing you can do is to raise the exposure compensation telling your camera you need it to be brighter.
