"Do you realise that every blade of grass is a different shade of green?" - from My Voice Will Go With You
It's my phone (SE S700i) on normal (default) settings. Possibly with the white balance set to "Daylight".. Nothing more. I shot about 15 frames, these were the best. Many didn't contain cds at all, as I'd misjudged the shutter lag..
A clear cloudless day-time sky is blue because molecules in the air scatter blue light from the sun more than they scatter red light. You'd be better placed to ask why the night sky isn't white (that has a much more interesting answer)
Babies come from when Mummies and Daddies love each other very much.
The night sky isn't dark merely because the sun goes down. The stars alone ought to be enough to make the night sky intensely bright.
Think about it this way. If we assume the universe contains an infinite number of stars scattered in endless space, we should see a star in any direction we look. It's like being in the middle of a forest - all you can see in any direction is tree trunks. The sky should be so completely filled with pinpoints of light that they should all merge into a uniform white glow.
However - the universe isn't quite old enough for this to happen. Give it a few hundred trillion years, and, if the cosmological constant turns out to be zero, or negative, the night sky will be white. and we'll all be long dead, as will our planet...
tef - I have an airgun, and tonnes of AOL cds. Many of them are in fragments at the bottom of the garden already.
