I'm precariously hanging over a sheer cliff to capture a straight-down perspective of the ocean waters below. With my assistant faithfully grasping my belt and a small nearby tree, i was able to get the camera gear over the edge enough to watch for the best mixture of rock and swirling waves.

well, not actually a mountain, nor made of anything hard like crystal – this is actually a very closeup shot at the edge from where a flower petal was torn. the tear left little shards of protruding flesh that when brightly lit, the whole thing glowed like an ice sculpture. this particular shard measures 0.046 inches tall (less than the thickness of a DVD) and you can see the elongated cells of white and purple that made up the flower petal.

vertical blade-like mounds of sandstone in eastern Utah

although passing for the scales on a blue dragon, this is actually an extreme close-up photo of the iridescent stripe on the wing of a Mallard Duck. the feather starts off with a main shaft (or quill) with hundreds of branches (barbs) protruding from the side. zooming in on one of these barbs, there are again hundreds of protruding tiny branches (barbules) on each barb. this photo captures approximately 4 of these barbules and their scale-like shapes. each of these 'squares' measure around 0.0012 inches across (less than the thickness of aluminum foil).

the American side of Niagara Falls

Standing next to the high-elevation 'Science City' atop Mount Haleakala, all i can see are these clouds and the small patch of land i'm standing on.

Wind blowing across the desert is dropping in ultra-fine sand like a constant dry rain. It is gently piling up everywhere on us and our equipment, but when the sun reaches its highest point, the light illuminates the raining sand and produces these shafts of light.

Having such a small body and graciously long wings, the Tiger Longwing doesn't flap quickly like most butterflies. Instead, it creates a very elegant slow-flutter to navigate through the rain-forest foliage in Brazil. It's motion is very different from what i'm accustomed to in the northern hemisphere, and i found it quite mesmerizing.
