Great photos

Two great photo links on MetaFilter today:

Georg Gerster aerial photography.
From his website:

“Georg Gerster was born in Winterthur, Switzerland, on April 30th, 1928 […]. Since 1956 he has been a freelance journalist specializing in science reporting and aerial photography. He has undertaken extensive visits to every part of the world, including Antarctica.”

Click on “Picture Gallery” in the left margin on his website to browse a gallery of his photos (direct linking does not seem to be working).
