This is one of many pools of water from underground hot springs at Yellowstone. As the water spreads out at the surface, it cools and allows a variety of different algae to sustain life. In this case, the algae that survives in the hotter temperatures is blue and green, and the somewhat cooler algae appears red and orange, forming a circular rainbow pattern to mark the temperature ranges of the water.

Typically when I shoot autumn images, I am biased toward early autumn so that there is more green with only some yellows and orange. I so much appreciate the lush greens that nature produces and it looks so full of life. Although fall colours are quite beautiful, I still prefer to maintain a fair amount of green in the photo as this makes the other autumn colours more pronounced and appreciable.

looking quite similar to an xmas tree with ornaments and tinsel, this is actually a photograph of a hostile invasion possibly taking place in your own backyard. if you see a plant with a white or light-gray powdery substance on the top-side of its leaves, it is probably an invasion of the 'White Powdery Mildew Fungi'. many different types of these spores spread with the wind, rain, birds, and even the feet of insects, and when the right type of spore lands on a suitable plant, it quickly takes hold by rooting into the plant. it then steals nutrition from the plant to grow an outbreak of thread-like structures over the surface (seen as white rice-like chains in this photo) which eventually block the plant's photosynthesis process and kills it. when the mildew fungus is sufficiently mature, it develops new sets of spores (inside the brown raisin-like containers) to travel in the wind and repeat the cycle. each of the brown spore-sacks measure about 0.0014 inches in diameter which is the thickness of kitchen aluminum foil.

it's a beautiful mid-spring day and i walked in many circles, ducking and bobbing my head for some time, trying to find the angle that best complimented this tree's glory. the clusters of large white flowers are quite bright against the surrounding forestry and such contrast made for a great shot.

about a week ago, my finger got pinched and created a tiny blood blister. now it's coming off and i decided to photograph the remains using a very tiny lens. this photo captures an an area about .057 inches wide (about the thickness of a DVD) and is of the outer regions of the blister where the dark dried blood meets the surrounding tough dried skin (whitish areas).
