Nowadays most people, from layman users to professional photographers, have switched to digital photography, with the advent of digital cameras. They range from simple, compact ones to advanced versions loaded with high-tech features. With so many new advances in digital camera technology, it is not possible to describe everything in one post. So, I will be discussing the various aspects of ISO settings alone in this post.
ISO setting is one of the most basic ways of controlling the light. Traditionally, ISO referred to film speed. As digital cameras no longer use film but instead use image sensors, the ISO equivalent is given. It primarily determines how sensitive the image sensor is to light. The common ISO settings are 100, 200, 300, and 400. Advanced models of digital cameras have ISO settings of 800, 1600, and sometimes even 3200 and 6400. To put it in simpler terms, a lower ISO number means better defined photos in low light whereas a higher ISO number means grainier ones.
Some useful tips:
• Use the lowest ISO setting to obtain the best image quality. You can easily set it from the default “Auto ISO” in the menu.
• For taking pictures where there is sufficient light, like on a sunny day, choose a low ISO setting, preferably 100 or 200.
• For indoor photography, low-light situations, or on cloudy days, you have to choose a higher ISO.
All this information regarding ISO should definitely help you take better pictures. So good luck!
