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.

although pesky, once you start to explore the common housefly, all sorts of amazing discoveries can be made. this is a super-closeup shot of the shiny metallic area on a blue bottle fly (blue housefly) capturing an area about the thickness of a playing card. the surface contains deep dimple-like cavities (similar to a golf ball) with an ultra tiny hair (about 1/8000 of an inch) in each one. the blue metallic colouring is mirror-like and reflects our lighting around like a highly polished automobile.

On my way back to the studio, after a routine walk with the camera, I stopped to rest a moment halfway up a steep hill. It was early autumn and the leaves had begun their colour cycle. Like most of us, sometimes I forget to look up to see what's directly above. In my moment of fatigue (too much gear), I arched my back to stretch and WOW! I was standing right under a perfect shot. A lower branch spread across my view with bright red leaves and a little higher up was a maple that turned yellow and just past that, a couple different greens from the oaks. Topped off with patches of deep blue sky, it was truly a colourful moment.

appearing as a beautiful iridescent wing from a magical creature, this is actually a small portion of a single grain of black sand. we were exploring a small clump of sand for a good shot, and noticed a tiny colourful spot sparkling out from one of the grains of lava rock. zooming in much more, we discovered this 'wing' shape measuring 0.0058 inches long (equivalent to the thickness of a sheet of paper). the entire grain of sand at this level of magnification, would fill 20 of these photos.
