ISO In Photography

ISO in photography is the ability to capture light sensor technology. The higher the ISO value, the greater the light that can be captured by the sensor. ISO to complement component factor exposure than shutter and aperture, especially when the combination of shutter and aperture values ​​have not managed to get the right exposure.

There is an option to specify the value of the sensitivity of the sensor / ISO ranging from AUTO, 100, 200, 400 up to 1600. The greater the ISO the more graniny the picture.

1. 100 & 200 = for conditions Glow / day

2. 400 = for light rather Dark / Indoor

3. 800/1600 = Night

There are even cameras to determine value is fully ISO AUTO, there are cameras lowest ISO value at 50, and there are cameras that can achieve very high ISO (3200, 6400 up to 10000).

ISO value the camera's in general are 100, 200, 400, 800, 1600, 3200. Professional digital SLR camera like NIKON D3, even capable of reaching up to ISO 25600 6400.12800 and with very low noise. Noise is small spots which looks at a photograph at high ISO settings. If the images in the zoom to 100%, noise will be seen clearly. ISO value be set too high will also affect the quality of the photo, so it does not appear like the color and detail is lost.

Generally, the value of the recommended ISO setting small. So the noise that will arise smaller and better quality image results. Moreover, if the photos will be printed with a large size. Small ISO also suitable for shooting scenery in which noise can be minimized as small as possible. High ISO values ​​are usually used for low light conditions, such as at night or indoor.
