High ISO low noise tutorial [updated] by Diangos High ISO low noise tutorial [updated] by Diangos
Update 1.1:

  • Added what is now step 1

  • Added further explanations in some places

  • Added green highlights to make text more readable

This took a hell of a long time to put together and with Corel Draw crashing on me on more than one occasion I'm seriously surprised I even made it this far.

At any rate, I wish you enjoy this tutorial a lot more than I enjoyed making it.

You may repost this tutorial or modify it as long as you credit me and share it forward.

If you have questions or requests please leave them in the comments.

P.S. Yes, that is the new PS :D - I'm trying it out.

Good thinking! I have actually worked with similiar techniques in Photoshop before, but never thought of using it to improve low light shots. I'll try it out at the next opportunity, thank you =)

Anytime. The averaging algorithm is incorrect and I haven't had time to update it. The opacity for each layer should be 1/1, 1/2, 1/3 and so on (in percent); meaning 100% opacity (bottom most layer), 50% 33%, 25%...

hello, I have a question. When the Photoshop tries to align the layers, does it only rotate and move the pictures, or also stretches them? I mean, after I load them, some of the layers are not rectangle anymore (they look like trapezoid, if you know what I mean). If yes, how to tell PS so that it only rotates or moves the pictures? not stretches? Thank you.
Diangos Featured By Owner Aug 25, 2012  Professional Photographer
Yes, PS also stretches the layers (as you can see in the tutorial). I'm not sure you can tell PS not to stretch layers - If you keep having problems with it you can use the free transform command on the layer (from the Edit menu) and lower that layer's opacity temporarily and try to align it by hand.

I hope it helps.

free transform is difficult if it includes rotation too. thanx anyway for your advice :D

Hello, this is my result:


It is a little bit blurry. I think I must use tripod. And my camera is not so good anyway......

Thanx for sharing this with us!! :D

What a great idea. Thanks for the tut. I usually use longer shutter times and a tripod for night shoots, but this is a great weapon in my arsenal now for when I don't have a tripod handy
