How to emulate Titarenko's long exposure stacking with digital?

Another mode consideration might be addition of the layers?

median will tend to remove the spurious motion from a scene and show the static background a bit better.

mean will do something similar-ish - averaging across all the images.

I can try to test something later…

This is an interesting topic. I could probably write a G’MIC command to assist you. However, I can’t view your images or contribute ATM because my internet has been bad the past week and I reached the cap a while ago ($5/GB ouch).

@patdavid Addition is the same as mean if you normalize it afterwards. If you don’t, then everything clips. I guess what you mean is selective addition…?

Excellent input from all of you, I am thanking you.

Much to learn, I still have.
