It's not really much of a shock to realise that we take most of our pictures of the sky from within it - or at least from the very bottom of it. Shots from planes (the flying type) and very high mountains are exceptions - but I dont seem to get window seats and I can't climb Everest!
This though occurred to me a few weeks ago, so I tried to take some images of the sky from within the ocean. That is I deliberately angled the camera upwards to try to photograph the sky through the surface of the water.
As you can see this was not entirely successful. I think most of the colour you can see is light being refracted back into the water from the plants and such like below - I think the boundary between the water and the air is acting like a mirror.
Anyway - I tried and I like this abstract image.
You can find more pictures - include ones that actually show the sky - at SkyWatch Friday.
Enjoy the pictures.
