Modern and high-end cameras can shoot without significant noise even at very high ISO values. But many of us still don’t own such cameras, so the ISO value where the photos are still usable is pretty limited. Koldunov Brothers share a simple Photoshop technique that will let you shoot In the dark even with a smartphone and reduce noise effectively.

Then, open images in Photoshop and load them into stack. Go to File >Scripts > Load Files into Stack. Select the files you want to load, and make sure to check the options “Attempt to Automatically Align Source Images” and “Create Smart Objects after Loading Layers.”
The final stage is the following: go to Layer > Smart Objects > Stack Mode > Median, and that’s it. Here are the results so you can compare:
