The question I answered was based on 35mm film. The maximum image size of a complete sphere on 35mm film would be 24mm. Therefore a 1 inch image on film would be the maximum size image that could be recorded on 35mm film. If the OP, as stated, did not care about the film format, 1 inch or approximately 24mm would be the maximum image size on film that the OP would be considering. The rest follows the logic out lined by the Greek philosophers approximately 2,500 to 3,500 years ago. The rest is supplied by W. Smith's book on optics, which is considered at many universities as a starting place for studying optics.

Any more hairs to split??
