What is ISO in Cameras and how it is being used?

Camera buying guideISO stands for International Standards Organisation and it defines the norms of the sensitivity of emulsion based film. higher the no. of ISO more sensitive is the film. It is very useful in the night shots because higher the ISO is more light will be sensed by the camera. When we think about the ISO is like the volume button on your radio if the signal is weak you push it up to compensate.

There are generally predefined ISO choices like 100, 200, 400, 800, 1600 and maybe 3200. You can also set any no. of ISO between the range to which your camera is compatible.In theory you could choose any setting you wanted but imagine how tricky that would be. There are three settings which combine to give you the exposure, these are Aperture, Shutter Speed and ISO. Each one can be changed individually to allow you to set then to what you think will give you the perfect exposure.

Important factors while changing ISO

  1. Light: If there is penalty of light in the frame than you should set ISO at low point and if frame didn’t have much light than you should set ISO at some high point to take good Photographs.
  2. Grains in the Picture :  When you put ISO at some high point photograph will get little bit of grains with more light into Photo.
  3. Tripod: Tripod is used when the object is still and we are trying to take photo with low shutter speed.
  4. Moving Subject: In photograph when the subject is moving we should keep the ISO at high point during the Night it will capture the movement clearly.

ISO is an important aspect of digital photography to have an understanding of if you want to gain more control of your digital camera and experiment with different settings and how they impact your images today – particularly learn more about Aperture and Shutter Speed which with ISO are a part of the Exposure Triangle.
