I took several photos of a drawing that a friend had made, but the quality of the photos is not very good, so I need software that can produce enhanced images by combining a stack of images of the same scene that were taken during a short period of time.
If you can’t find a tool, this has worked to some degree for me. Open on e.g. GIMP, scale the images to the desired size in different layers, use perspective transform to align them very precisely, then set layer opacity so that you can merge them down with equal weight on each photo. It’s not a really good method, but might do the job. Good luck!
