Low Light Shooting

[thunderkyss]

Keep in mind that any given EV (Exposure Value) can be expressed with many combinations of aperture, shutter speed, and ISO as long as the total exposure (the combination of aperture, shutter speed, and ISO) is equal. For example, f/8, 1/400 second, and ISO 3200 can be replace by f/4, 1/800 second, and ISO 1600 since they provide an equal exposure (if I added things right).

That makes sense, thank you.
