I didn't know the precise terminology for it, so my 'spherical' was just a
description! I realise there is more to it than just a photograph of a ball,
but I was trying to keep it simple to distinguish between the two projections.

(Actually you can use a ball photograph without processing, as long as you can
work around the 'pinched' area - to say nothing of the photographer!).
