How to Prevent High ISO Noise
It is not always possible to shoot in low ISO. For instance, in a low-light environment, you have to use a higher ISO setting. For today’s tip, I show you how to prevent High ISO Noise.
.
What is High ISO Noise?
Generally speaking, when shooting with high ISO, our digital cameras create digital noise or grain. The high ISO noise reduces the sharpness of pictures. So, the best way to prevent high ISO noise is using a lower ISO.
.
However, we need to use a high ISO in many situations, i.e. our kids’ hockey game. In this example, if you use a low ISO setting, you have to use a slow shutter speed. Therefore, all the photos will be blurry! So, you must use a high ISO to take sharp images.

Low-light, fast-moving subjects, and High ISO
Should you use a low ISO and slow shutter speed to avoid the noise? But, since the subject is moving, you will end up with blurry images. Or should you increase the ISO and using a faster shutter speed to freeze the action? That is a big dilemma.
So, here is the solution to prevent high ISO noise; Shoot photos slightly over-exposed.
Slightly over-exposed photos conceal the high ISO noise to the point that it makes the picture sharp enough for prints.
If you shoot in any of the semi-automatic modes, Shutter priority or aperture priority, use the Exposure Compensation button to increase the exposure by one stop (+1.) If you use Manual Exposure, adjust the exposure to +1, and you will be amazed how this simple trick can easily prevent high ISO noise.
