Using different camera exposures, 1/80, 2/5 and 2 seconds, the two regions of a lunar eclipse can be seen. The outer penumbral shadow is where the sunlight is dimmed and the inner umbral shadow is where the much dimmer sunlight can be seen as a red colour as it reflects through the Earth’s atmosphere.
