What, exactly, is ISO: The ISO setting on your camera is how you adjust your camera's sensitivity to light. This is reminiscent to the speed of film in the pre-digital world. The faster the film, the higher the number, and the larger the film grains. Similarly, in digital photography, the higher your ISO setting the more sensitive your camera will be to light, the less light you will need, and the faster your camera will take pictures; unfortunately this is usually at the price of quality, and your pictures will often turn out "noisy". The initials ISO does not actually stand for anything apparently, but actually taken from the Greek word Isos, meaning equal; at least, that's what word on the street says.
Setting ISO: Most cameras seem to let you set your ISO, and it's usually under the general menu settings.
How-To Use ISO:
- Get snappy pictures in lowlight situations.
- Know how to get nicer pictures, even if it means a somewhat longer shutter speed.
