@dthompson no disrespect intended, but couldn't they just use different lenses or distances to project a bigger image? What is it about the film? This is probably a very stupid question lol

@strawburster bigger film = more information. if you projected 35mm and 70mm to the same size, the 70mm will be sharper.

@dthompson interesting, from a physics background I've always focused on the other end of the camera, the aperture size, to increase sharpness, sometimes going up to the size of Earth: https://www.jpl.nasa.gov/edu/resources/teachable-moment/how-scientists-captured-the-first-image-of-a-black-hole/ but I suppose that makes sense if the individual crystals in the film are limiting resolution at that scale. Curious to hear what you think afterwards!
