This noise reduction technique will reduce noise without sacrificing sharpness

 

 

When you need to shoot at higher ISOs, the tradeoff is that you often have an image with a lot of visual noise. This can simply reduce fine details, but it can also introduce false colors into your shots. In any case, it's unsightly and there are many ways you can reduce noise during post-processing.

In a new video tutorial, Mads Peter Iversen shows off a specific technique for reducing noise. The technique involves shooting multiple images and then stacking them in Photoshop. This method is great because it allows you to reduce noise without reducing the sharpness, which is the biggest drawback with traditional noise reduction processes applied to single images. It's not perfect for every situation, however, as there are some limitations. An obvious one is that you can't use it for photographing moving subjects and another is that you need a tripod. You can correct for a little bit of movement when stacking, but it's tricky and it will require cropping. To learn how to use this method and see its results, check out the video below.
