well its not TOTALLY defined but quite defined:
a good argument i was given was overexposition
but this argument is broguth down by yor being able to see the grey of the seas in that picture
also you cant deny that ALLL diagrams of moon eclipses avalaible on the net are FALSE since they portrait the umbra as JUST ONE TONE shadow when the sade should gradually go from 0% to 100%
i withdraw my saying the sky is a dome i understand sternjager annoyance
yet i keep ALL diagrams avalaible on the net on moon eclipses except mine are wrong
