ISO

ISO stands for International Standards Organisation and when releated to photography, it is a industry scale for measuring the sensitivity to light. In today’s world where the film has been replaced by a digital image sensor, ISO basically relates to how much sensitive the sensor get’s to the light that enters the camera. ISO is measured in numbers where the lowest number means least sensitive to light (example ISO 100) while the highest being most sensitive to light (example ISO 3200). Almost all digital cameras today allow to control the ISO settings and so it is important to know what it is and what effect does it have on the snap that you take. After all, we all want to get that WOW factor in our photography – right?
