The evening started with clouds that cleared slowly as the eclipse began.
The penumbra progressed across the "face" of the moon,
It was clearly curved!
The air was still hazy with high cloud blurring the occasional picture.
The "diamond ring" stage.
A switch of exposure (and camera lenses) was possible once the bright light was gone.
The last glimmer of bright light disappears and the moon is bathed in "sunset light".
Only light that passes through the earth's atmosphere is now hitting the moon.
As in sunsets, the blue light is scattered away and mainly red light is left to hit the moon.
It doesn't take long before the other edge of the umbra shadow is reached.
Light that has not been filtered by the earth's atmosphere starts to reach the lunar surface .
Gradually, the edge that first darkened, now gets brighter.
Bright enough now to start requiring a change in exposure levels.
It seems very bright compared to the full umbra, but we're only seeing the penumbra again.
Thin clouds, and the occasional tree branch, caused blurring from time to time.
Finally, "moonlight" starts casting shadows on the ground again, In a few minutes, the full moon will be returned to full brightness (but it's time for bed!)
