On such a parameter as ISO, everyone at least once "came across" in the menu of his camera. However, not everyone knows about him. Let's see what ISO is in the camera.
Under this parameter is the camera's photosensitivity. The sensitivity is higher, the higher the value of the specified parameter, and from a high value in the photo a lot of noise appears. That is why experts recommend using a low ISO value to get high-quality photos without noise. When shooting in low light without a tripod, increase the value of this parameter. If the aperture is also fully open, you can increase the shutter speed so that the photo does not work out blurry. If we talk about what ISO is in the camera, it should be noted that when shooting at night, you should still use a tripod, and also set the value of this parameter below. When using the flash, its high value will not be necessary.
It is worth noting that the amount of noise in the photo with a high ISO value directly depends on the size of the matrix used in the camera. If these are compact cameras, then with ISO 800 you should not expect a good result. Poor lighting will cause the photo to be smeared completely. In this case, the camera should be held on a tripod using a low parameter value. When working with professional or semi-professional equipment, you can set its value four times higher, while the quality of the pictures will be simply amazing.
Speaking about what ISO is in the camera, it is worth recalling such an opportunity as Auto ISO. It can be noted that this function is quite moody. If you use a soap box, then you should set the ISO 100 and not bother. When using a SLR camera, you can limit Auto ISO to a certain extent. For example, you set the highest value to 800, then the camera will be unable to raise it higher, even if it is appropriate.
If we talk about what ISO is, then it is also worth noting that the values of this parameter can be quite diverse. In modern cameras, a number of values are found in the range of 50-204800. The amateur range usually ends at around 1600, and for more advanced cameras it reaches 3200. At higher values, there is no point in ordinary life, they can be useful for sequential shooting performed on professional cameras.
If you use digital cameras, there are certain places where high ISO values can come in handy. First of all, it should be said about events with active actions, rooms where it is impossible to use flashes for one reason or another, but at the same time the lighting in them is not enough quality. When taking pictures of the city at night, it is better to use a tripod, while setting a high value for photosensitivity, but without using a flash.
Now you know what ISO is in the camera.
