Believe it or not, I still have a bunch of photographs from my recent trip to Yellowstone National Park. This one of the microbial mat formed by the run-off of the Grand Prismatic Spring is one of my favorites. Although we could not see the spring in its entirety, the mats were amazing. These microbial mats form vivid colors around the edges of the mineral-rich spring. They produce colors ranging from green to red. The amount of color in the microbial mats depends on the ratio of chlorophyll to carotenoids and on the temperature of the runoff. In the summer, the mats tend to be orange and red, whereas in the winter the mats are usually dark green.
This image was taken with my Canon EOS 5DS using my Canon EF 16-35mm f/4 Lens set on 24mm. The camera was set on Manual mode with the aperture set at f/14, shutter speed at 1/25th of a second and the ISO set at 100. I used a sturdy tripod to create a solid foundation and my Kirk Long Rail to avoid Parallax Errors on the panorama. I captured seven images and stitched them together into one image using Lightroom. I finalized the image in Photoshop using Nik Color Efex Pro.
