Just a quick reminder, the higher you set your ISO, the more grain you will get in your photo.
Now, some photographers may not be so concerned about graininess or ‘noise’ at high ISOs, but there is something else you should be aware of…
Lack of Color Depth
The more you increase your ISO past a certain point, the more you decrease color depth in your image. That means there are fewer colors present in the image.
It may not be a deal breaker or noticeable in a social media post, but you will see it if you print out your images.
Just something to be aware of!
