What is ISO and Noise?

Sure many are still wondering what the ISO is actually right? Some still think if we took pictures with high ISO images more easily taken and did not produce any vibration. Is this statement true or false? Posted whether we talk.
ISO is simply defined as the sensitivity (sensitivity) to light.
If you think about the camera wearing the then-first film, the film box (or some call the camera) it is written the word 100/200/400/800. This is the sensitivity of the film on digital cameras cahaya.Bagi time now, ISO refers to the sensitivity of the camera sensor to light.

The lower the value, the lower the sensitivity of the film / sensor to light and the 'noise' generated is less.

So it is contrary to the higher ISO values​​. The higher the ISO, the more sensitive the film/ sensor is to light, but more 'noise' will be produced.

WHAT IS NOISE?

The term 'Noise' or a translation into the language directly means noise. But this does not mean the picture is noisy or shouting, noise refers to every rough details in the picture you take. For example,

You can look at ISO 80, the details of the picture clearer and less noise createdcompared to the ISO 1600 is generating more noise.

WANT TO USE ISO SO HOW?

The first question that arises in our mind, what is the best ISO setting for my camera?Better whether low or high?

100? 200? 400? 800? 1600? 3200? which one?

Ok .. ok .. do not konfius k.. I tried to explain in detail on the ISO from A to Z.

The most appropriate ISO value for your camera should be according to theenvironment around you, whether you're in the dark (night), some lights (indoors) orbright light (outdoors). From my personal experience under the settings are best forthose who are new to photography and want to experiment on the ISO.

ISO atmosphere

100 Outdoor	(Light Very Light)
200 Outdoor	(Light light)
400 Indoor	(Light Less)
800 Indoor	Light Very Poor)
1600 Indoor / Night	(Light Almost Nothing)

However, you are still free to use high ISO anywhere you like because in Malaysia, there is a cameraman who knowingly makes pictures taken with a high noise as a technique of his own, or trademark. With high ISO as well, pictures taken can result in lessvibration for a faster shutter speed and camera sensors capable of storing / recordingimages more quickly. This is because the sensor is more sensitive to light and thesensor does not require a long time to record the image.

In addition, you can also ask yourself questions d under to yourself, before deciding to use any ISO.

Light - is light enough or very poor light?
Noise - I want a clear picture of high or noise?
Tripod - Do I use a tripod?
Moving objects - Is the object I want to take a moving or static?
