A different view of Canyon X, Navajo Reservation, Arizona, treated with a flood filter.
The last few photos of the canyon, including one with a photographer for scale, can be seen here: http://goo.gl/XDhCUo
Since I was asked about it.......to process the light and dark shades in the canyon, using RAW, I bracketed 5 shots (or sometimes 7 shots) and then, instead of using HDR, from the 5 or 7 bracketed images, I chose the one with the best mid-tones (Image 1), and the one where the highlights weren't blown out (Image 2), and then processed them for the best exposure of the shadows and highlights in Adobe Camera Raw, keeping Image 1 as the main image. I then combined them in Photoshop (Select the blown out areas in Image 1, then Select Image 2, copy it and choose Paste Special, then 'Paste Into' the selected area in Image 1). Do some 'tidying up'. This only works with RAW since you can retrieve 3 stops of detail from the highlights, and from the shadows, from a RAW file. For this image, I then applied a flood filter.
