Slide scanner? It's incredible how much contrast old slides have. If you try to photograph them, you quickly reach your limits and are constantly adjusting the aperture. I spontaneously had the idea that 13.5 f-stops of dynamic range would be better. The same goes for filming Super 8. Has anyone tried this with the Action 5? I could imagine projecting onto clean white cardboard and filming slightly off-axis so that there is no white spot in the centre. The slight parallax error could be corrected in post. Of course, it could also happen that the image "pumps"; a frame could prevent this.
