Jellyfish Lake in Palua, Micronesia is famous for gazilions of these Mastigias jellyfish, which have adapted to exile within this isolated, brackish inland lake. Sea water does sieve into the lake via tidal changes through underground channels. This was shot on film and even the digital scan does not retain the gradations of tones between the sun ball and the darker green. I would not even attempt this shot on my D2X. I'm hoping the new Nikon D3 will do better.
