The three frames that I used to create this stitched panorama were created with the with the tripod-mounted Canon 70-200mm f\/4L IS lens and the EOS-1D Mark IV. ISO 200. Evaluative metering +1\/3 stop: 1\/30 sec. at f\/20 set manually. When creating the images for a stitched pano I fist level the tripod by centering the floating bubble on the top of the Mongoose M3.6 in the scribed circle. I do this by adjusting the legs individually. Next I rotate the lens in the tripod mount while checking the double bubble level in my hot shoe to ensure that everything is square to the world as I pan and overlap the images. <\/p>\n

I did extensive clean-up work here removing more than a few tree tops from the lower edge of the frame, a large tree on the right hand side, and about half a dozen folks from the boardwalk. I will make another version with the boardwalk removed. So far the clean-up required about two hours of painstaking work; to do the job right, you need to work at high magnifications. I used the Clone Stamp Tool, the Patch Tool, and about 50 small Quick Masks all as described in detail in Digital Basics<\/a> and in APTATS I.<\/a> <\/p>\n<\/td>\n<\/tr>\n<\/table>\n\n\n\n

Grand Prismatic Springs<\/h2>\n

Thanks to both Dale Robert Franz and Roman Kurywczak who shared directions to the spot that afforded the spectacular view of Grand Prismatic Springs in the Midway Geyser area of Yellowstone National Park. The climb up a very large hill (or a small mountain) was extremely difficult. Denise Ippolito was kind enough to help me both on the way up and on the way down. Up was more strenuous due to the elevation and the rough terrain, down was far more difficult because of the steepness and the loose rocks and gravel. On the way up I was breathing hard and resting often–the vertical climb was probably about 500 feet. On the way down I was motivated by fear; for the last half of that climb I spent most of the time on my butt. After the climb up and down both Denise and I felt exhilarated. I will be back soon to share more of our Yellowstone experiences. You can see some of Denise’s images on her blog, A Creative Adventure<\/a>.<\/p>\n
