learn iso on photography.
In the sense of ISO or ASA (in the photographic film) is the ability or the sensitivity of the camera's sensor to light. As a basic function of ISO in photography, the greater the value the ISO setting of the camera, the more sensitive and the light is obtained. ISO feature on the camera will be part of a triangle of exposure in addition to the Shutter Speed and Aperture.

Ok let wished again, eg ISO = gravel is then inserted into the glass to be filled with water. With the help of these pebbles, to fill water into the glass to fit on the rim of the glass, it does not require a lot of water. So also with the ISO on photography, the higher the ISO the less cahay needed to achieve the proper exposure.
Other than AUTO, ISO value on the camera unit is marked with values starting from the number 50/100, 200, 400, 800, 1600 and so on according to the specifications of the camera. On professional DSLR cameras, ISO Nikon D600 for example, is able to achieve up to a value of ISO 25000.
In addition to increased sensitivity to light is obtained, the ISO can cause noise in the picture. However, for digital cameras in today's era of technological development, high ISO has not become an obstacle. D3 with ISO 25600 still get images with low noise.
No one yet knows the term photography NOISE? Noise is small spots which exist in the photo. Noise addition, by using a high ISO value can also cause a reduction in the quality of the resulting image. Suppose colors less out, so less detail photo / tajem etc.
When to Use ISO
High iso typically used when low light conditions, such as when photographing at night or indoor. When to pay attention to or use ISO on the camera? when a combination of two triangular sections exposure shutter speed and aperture not get the exposure or the right light.

When conditions like that you can raise the ISO value to get enough light and obtain the ideal shutter speed. Suppose that on one occasion you want to capture the moment engaged in indoor low light. Ideally for capturing moments that quickly is to use a high shutter speed, aperture up to about the size of smokers, for how.
In the case above, I have to use the speed of 1/250 so that the camera can record moving moments in the indoor space. However, the lens only has the widest aperture F3.5. Without increasing the ISO value, I only get the photos that underexposured (EU) gelaaap. Well, with lock shutter speed and aperture F3.5 1/250 I should add value to the ISO to obtain proper exposure.
In general, in photography many who advocate for using the ISO as small as possible. To avoid noise and get sharp photos. Moreover, if the images you want to print the large size, small Iso has become imperative. But in some cases, Noise sometimes necessary to add to the impression of the photo more dramatically, for example, BW photo.
