Compare images, removing differences?

[FurryEskimo]

I play Elite Dangerous and wanted to edit some shots, but it's so difficult sometimes!  I wanted to take some very similar shots of my ship, then edit out the background, but it's proving difficult.  I have multiple images with a nearly identical shot of my ship, but vastly different backgrounds and was curious if the program could compare the images and automatically remove the differences?  I saw a program years and years ago that could do this, to get images of famous locations without people in the shots, but I've yet to find a modern program that can do it,,

There's no automatic way to do that in Paint.NET. However, it's to very difficult to do it manually.

 

Here's a tip:

Setting a Layer's Blend Mode to Xor will show all different pixels, in comparison to the layer below it.

Outside of Paint.NET, see this solution:

But, editing out the background is different to median stacking, for that, you do have a solution within PDN:

While I appreciate the kudos, the real kudos should go to @dipstick who found it first.

 

 

Taking his tip and @welshblue suggestion to use alpha-mask, presto the tutorial was born.

 

The tool of G'Mic was found when watching a video on YouTube about G'Mic in Photoshop, Gimp, Krita, and Paint.NET.  I had no idea that G'Mic had the tool to remove background as well until that video on YouTube.  Speaking of video, I really need to redo the video on using G'Mic.  It is bloody potato, IMHO.

Correction - Erm, it's not available there. It is available in Blender, and a few FOSS video editors as well.
