Here is an additional image as promised. This is a panorama of 5 images of the mouth of Santa Elena Canyon. Topography, geography, and geology of the Big Bend region is pretty complex, and looking at a good topo map will help understand what is going on here. The short version is that the Rio Grande cuts through a large "plateau" which straddles the boundary between the United States and Mexico. This view is taken with the center looking just a little south of west.

Manual exposure based on matrix metering of the center portion of the image was used to insure consistency among frames. Nikkor 24-70 lens at 32mm. ISO 200, f13, 1/640 second. No post processing, although I am considering lightening the cliff face slightly to provide better separation from the canyon walls behind..

This is an early afternoon scene. My goal is to return and recreate this as an early morning image for more uniform lighting. I would also capture component images with vertical framing in order to facilitate stitching the panorama together and to capture more of the sky.

I have returned to UHH after an absence of almost a year. I felt that some additional education and practice was called for, since I was finding myself 'out of step' on a number of topics of discussion. One effort that I undertook was to participate in a night sky/low light workshop at Big Bend National Park and some of the surrounding areas. Here is an image that I captured during a session in Terlingua, an old mercury mining town on the western edge of the park. Nikon D810 and Nikkor 14-24mm zoom at 14mm and f2.8. Exposure was 1/3 second (it was about 25 minutes after sunset). I will post a couple of additional images in a few minutes.
