Why Are My Photos Grainy? ISO Tutorial

Why are my photos grainy?


Have you ever wondered why your photos turn out grainy? In digital photos, that grainy look is digital noise.

Why do my photos look grainy?

There are a couple of reasons why you might have too much digital noise in your photos.

  • It could be that you have too high of an ISO
  • Or maybe you are underexposing your photos

Come watch this video and see photo examples of what happens when your ISO is too high. And, why it’s important to expose your photos properly. You’ll see why trying to brighten your photos significantly in editing can bring out even more noise than using a higher ISO to begin with.

You’ll learn how ISO impacts the noise in your photos. You will also learn why it’s important to expose your photos properly.

ISO is one of the three things that affect exposure when shooting in manual mode, so it’s really important to know how to use it.



What about noise reduction in editing?

Now you know how to reduce noise while taking your photos. Does that mean you don’t have to reduce any noise while editing? Not quite. You’ll still want to use the noise reduction panel in Adobe Camera Raw. To see exactly how to do this, check out my editing video where I show my simple method for reducing noise.
