For some time now, compact cameras have become a dispensable object for users, since thanks to the cameras that integrate the latest generation mobile phones the photographs come out practically the same, saving some distances, in those cases in which we can vary some other settings when taking the shot in question.
Our smartphone is with us almost 24 hours a day, which makes us allows you to take pictures anytime, anywhere. On many occasions, especially if we take photos when we are partying in a poorly lit environment, the device raises the ISO value so that the image can capture the entire scene without movement.
The problem with using a very high ISO value is that the quality of the photograph suffers in terms of sharpness. Maybe on the smartphone they look great, but if we expand or pass them to our Mac, we can see how the image quality leaves a lot to be desired. The problem with high ISO is that we can see the grains that make up the image contrary to what would happen if we had used a lower ISO.
For this we have to use applications such as Photoshop or Pixelmator to improve the quality of the image, or we can use the Noise Reductor Pro application available on the Mac App Store for free but as usual for an unlimited time.
The operation of this application is very simple and it does not require hardly any configuration, since it deals with the image reducing grain size to sharpen the image and improves its quality, especially if what we want to do with it is to print it in a considerable size. The application does not work miracles, but to get out of trouble it is more than enough.
