Cute gimmick this G'MIC-Qt. I've been using it for four or six years myself. Very useful collection of plugins, effects, filters, and other tools that save tons of time.
This is neat! Didn't thought of using this technique for removing noise, but it makes perfect sense. Well, I don't do much photos nowadays anyway. Isn't this the same exact technique to remove tourists from tourists attractions ? Like, you go to Italy or Greece and want to take a photo of a fountain or a sculpture. You can see it, but there's ALWAYS some people there, which prevent you from taking a clean shot of the fountain, unless you block the area for a bit. You can set a tripod and take multiple photos (preferably more than 10), but not in immediate succession, but at longer time intervals, like 30 seconds or one minute. Assuming it's not THAT crowded, that the people going between you and the fountain are usually just passing then, using this technique, you can get an image completely without them. The idea is that using the "median blend" for each pixel, the one that has the same color the most amount of times, that will be the final pixel. And in this context, the fountain is the one that will appear the most often, and with the same color.
I run Linux. I managed to download GMIC and have an ICON on my linux software loader/choices. I cannot however get it installed into GIMP as a plug in.
Use a tripod? 😂 Okay, you used one. Why not set the ISO lower? Image stacking to me makes sense only for moving objects or cameras. Structure from motion or superresolution.
There are plenty of articles about image stacking if you want to understand why it exists. If you want to reduce ISO to remove noise then you also need a long shutter, and if it's not dark out you'll have to learn to use strong ND filters too.
Why the hate Julius? This is a very great tutorial on how to do something very complex using free open source software. Stacking plus alignment in a single piece of software is not easy to come by
Have used GIMP in the past. Very useful, never heard of this technique, thank you for sharing

Very nice tutorial. I use GIMP myself all the time. It's awesome.
It's nice to see a Windows user using GIMP. Pretty much the only thing I use it for is drawing up puzzles and printing them off.

Often people will use a strong neutral density filter and a very long exposure for that.

The best example of noise reduction is on the sky...
