Photography: how to use ISO values

In today's article we talk about photography, and precisely on the value of the optimization ISO depending on exposure or aperture.

We begin by saying that the term ISO indicates the standard to which we are referring to indicate the sensitivity of the internal sensor of the digital cameras in relation to light. In other words, by setting a low ISO value we will have a little light-sensitive sensor and a photo darker, vice versa (with the same aperture and exposure times) with very high ISO values ​​we will have a more sensitive sensor and a dramatically clearer picture (with some grain of digital noise in most, but more about that later).
