I had to make a steep hike up a very slippery hill to get this vantage point. I really like the colors and patterns created in nature.
Nikon D800, 70-200/2.8 @ f16 and 200mm
1/90, ISO 400
Used CS6 to apply contrast, curves, a little dodge and burn, and sharpening. No vibrance or saturation added.
Here is a little information on the colors: "Water at the center of the spring, which bubbles up 121 feet from underground chambers, can reach temperatures around 189 degrees Fahrenheit, which makes it too hot to sustain most life (some life does manage to exist, but its limited to organisms that feed off of inorganic chemicals like hyrdogen gas). Because there's very little living in the center of the pool, the water looks extremely clear, and has a beautiful, deep-blue color (thanks to the scattering of blue wavelengths — the same reason oceans and lakes appear blue to the naked eye). But as the water spreads out and cools, it creates concentric circles of varying temperatures each signified a different temperature. And these distinct temperature rings are key, because each ring creates a very different environment inhabited by different types of bacteria. And it's the different types of bacteria that give the spring its prismatic colors."
