What is the meaning of ISO in cameras?

Answer 1

"ISO" is a word that represents the International Standards Organization, or as it is more commonly known, the International Organization for Standardization. This organization is based in Switzerland and they set a lot of international standards, including the measurement system for film sensitivity (which translates to digital Photography).

In photography, the ISO is pronounced "EYE-so," not "eye-es-oh," however it does not have anything to do with the Greek "isos," as others have claimed. Here is the entry in the World English Dictionary:

ISO (aɪsaʊ)

-n

International Organization for Standardization

[Greek isos equal; often wrongly thought to be an abbreviation for International Standards Organization ]

Answer 2

ISO stands for International Organisation for Standardization, which is an organization that creates standards. With respect to camera film and sensors, it is a means of quantifying the sensitivity of film or camera sesnors to light.

ISO 100 is a low rating compared to 1600, thus more light or longer exposures are needed to create an image with a low ISO setting or film. High settings or faster film may eliminate that issue, but there is a trade-off because they produce more "noise" (digital images) or larger film grain. When striving for technical quality, the lowest setting or film speed that will permit mid range shutter speeds and apertures will usually produce the best all round results.

Answer 3

ISO is a measure of sensitivity, the same as the old ASA, used to rate the speed of film in film cameras. Film that is very sensitive and works well for fast-action photographs or reasonably fast exposures in dim light is rated (for example) ISO 400 to 1000 or more. Films slower than this are rated ISO 25-300, or so. For digital cameras, manufacturers state an film-equivalent sensitivity. Sensitivity is important, but some characteristics such as good color balance, and power usage might be sacrificed. THANK YOU VERY MUCH FOR THE APPROPRIATE ANSWER . BUT IS THE LOGIC SET WITH SENSOR OF THE CAMERA OR LENSE AND SHUTTER SPEED? REGARDS YATIN

Answer 4

The ISO is the sensitivity to light, and you would have to change it before the picture is taken. ISO is similar to the exposure time in that it can make the picture brighter or darker but the difference is that the ISO changes how large the cameras filter opens and exposure time changes how long the filter stay's open. This is helpful when you are trying to take a picture in the shadows and you need to brighten the image but the subject is moving fast, say a bird is flying by, you need a fast shutter speed but it is dark so you need a higher ISO. ISO is great in this case but if you can, use the shutter speed instead because the higher the ISO the more noise you picture will have. Hope this helps!

Answer 5

its a deepand of camera as like a "image sensor of camera"....
