I think we’re talking at crossed purposes here.  I think your talking about the illumination of the Earth by the Sun as seen by a traveller in Space like in a telescope photograph of one of the planets.  I’m talking about the reduced view of the horizon due to the curvature of the Earth itself.  There’s an order of difference likely between your distance from the Earth and mine.   I think I’d want to know a bit more about the original, original photograph before deciding which view is correct.  DaveP
