Last but not the least, it is time to get familiar with the concept of ISO. Well, by now you all must be expert in adjusting your camera settings depending upon the choice of picture you want to click. So, let’s understand the last element of the exposure triangle and make our click.. picture perfect.

ISO

ISO refers to the sensitivity of the camera’s image sensor to light. It is the final variable in the exposure triangle which we are going to experiment with. Suppose you have to shoot in a darker environment, in such cases, higher ISO will allow you to work with less light. Increasing the ISO surely allows you to click images in a darker environment, but it comes with a price. Higher ISO will lead to increased noise and less detail in the image.

While working with good lighting, you can keep your ISO at a lower end which means less light will be hitting your camera’s sensor. To avoid digital noise in your pictures, try experimenting with different ISO values depending upon the lighting conditions and environment. If you are shooting indoors, then ISO can be varied between 100-200 and if outdoors, then you can vary the range between 800-1600.

If you have mastered the aperture and shutter speed, then you can easily work with ISO settings. All you need to keep in mind is.. avoiding the digital noise in your image which will diminish the details of the image.

Happy Clicking! 🙂
