International Standards Organization (ISO) is basically the light sensitivity rating for the digital image sensors. In basic terms, ISO is the level of sensitivity of your camera to the available light. But, what is the full form of ISO?

ISO Full Form stands for International Standards Organization.International Standards Organization (ISO) is the level of sensitivity of your camera to the available light or we can say that, it is the light sensitivity rating of a digital image sensor.

International Standards Organization (ISO) is a system for quantifying the sensitivity (speed) of a photographic emulsion, or a solid-state digital-camera’s image sensor to the visible light.

Normally, it is followed by a numeric value. For example, ISO 100 or ISO 64/19˚.

What is ISO in Traditional or film photography?

ISO full form is International Standards Organization in traditional or film photography was the indication of that how sensitive is a film was to the light. As said above also, that ISO was measured in numbers like 100, 200, 400, 800 and etc.

But one thing, the lower will be the number the lower will be the sensitivity of the film and the finer will be the grain in the shot you’ll be taking.

What is ISO in Digital Photography?

In the Digital Photography the International Standards Organization (ISO) measures the sensitivity of the image sensor. 

In digital photography the same principles will be applied that was applied in the film/traditional photography i.e. the lower the number the less sensitive your camera is to light will result in the finer the grain.

So, it was about the lower numbers. But, what about the higher numbers? So, as high the number will be it means that the sensor will become more sensitive to the visible light which allows you to use your camera in the darker situations.

The cost of doing so is the more grain although, the cameras are improving and updating all the time but today many people is able to use the high International Standards Organization (ISO) settings and they still take very useable images.

Now, let us see where we can choose the higher ISO. So, you might want to choose a higher International Standards Organization (ISO) would be photographing an indoor sporting event where the light is low and also your subject is moving fast.

So, by choosing a higher ISO you can use a faster shutter speed and you can freeze the movement of the object for a while.

What are the questions you might ask yourself while choosing the ISO?

When choosing the International Standards Organization (ISO) settings I generally ask myself the following four questions: –

  • Light- It is the subject well lit?
  • Grain- Do I want a grainy shot or one without the noise?
  • Tripod- Am I using a tripod or not?
  • Moving Subject- Is my subject moving or static/stationary?

Now, the answers to all these questions/situations are as follows: –

  1. If there is a plenty of light, I want a little grain, I’m using a tripod and my subject is static/stationary so generally I will use a pretty low ISO rating. 

2.If it’s dark, I purposely want a grain, but I don’t have a tripod and also my subject is moving then I might consider increasing the International Standards Organization (ISO) setting as it will help me to shoot with a faster shutter speed and still expose the shot well. Of course, the trade off of this increase in ISO will be noiser shots.

International Standards Organization (ISO) is an important aspect of the digital photography to have an understanding of if you want to gain more control of your digital camera.

Try, to do experiments with the different settings and learn to do something different and also see how it impacts your images.

Q&A on ISO

Q1. What is the full form of ISO

Ans.1.ISO full form is International Standards Organization, Also ISO full form in Hindi is “अंतर्राष्ट्रीय मानक संगठन”.

So, I hope you are clear with the term International Standards Organization i.e. ISO, how ISO is used in the camera and many more information related to it.
