Relative aperture has nothing to do with negative area (or positive area, or
sensor area!). It's simply a measure of the aperture size relative to the
focal length of the lens. Thus f/1024 is a 0.5mm aperture on a 512mm lens -
mathematically speaking.
Averagely small, aye, mebbe.

What does an f1024 aperture look like? Does it occur with a averagely small
aperture and a huge negative area?
