After the boiling hot mineral water oozes up from the earth, it eventually starts to cool and the mineral elements fall out of suspension. Since the edges are cooler than the middle, the sediment builds up a little perimeter wall one grain at a time. Over time, large cascading pools are created as they overflow and puddle to create more.

a super closeup shot of a bee's wing. the longer hairs are on the side of the wing facing the camera, and since the wing is mostly transparent, you can also see the hairs on the opposite side which appear shorter as they fade off into the distance. each of these ultra-tiny hairs have a diameter about 1/8000 of an inch (1/4 the thickness of kitchen plastic wrap).

This large Bird-of-Paradise bloom gave me quite a challenge. I was hiking in a tropical rain-forest when i saw glimpses of this beautiful bloom. The only trouble was the best side to photograph was rather hidden by thick foliage with no practical way to get closer. I found a peek-hole through the network of leaves, but it was very high, so i stretched the tripod to it's full height and then more so by greatly decreasing it's base to obtain just enough height to peek through this hole in the foliage. Then added a very large zoom lens on top of this very unstable camera setup. After waiting some time for everything to settle down from micro-movements (including not breathing on or near the camera), i was able to capture this exotic shot.
