The marks of man and the forces of nature exist side by side in the skies over Zion National Park. I shot this scene at two different moments. Earlier, there were two clearly defined contrails, one vertical and the other diagonal. It made a very effective image – you can see it in my travel article on this journey at http://www.worldisround.com/articles/278784/photo15.html
Compare it to this image. The rear contrail has faded considerably, leaving behind a larger field of texture. The primary contrail has widened some as well, and now has a textured spine running down its side. By turning the image horizontally, I crop into both contrails and zoom the lens much closer to stress the contrast in textures between the two contrails. Both of these images tell the same story, but in different ways – largely due to the nature of texture and how I chose to stress it.
