Again an attempt to improve an earlier uploaded picture by my newly acquired photo editing software (Helicon Filter). I had a comment that the earlier picture
http://www.fotothing.com/senna3/photo/7b88084da4c48ed54b81aa138ab29423/start=308 was too "blue" and unnatural for the Grand Canyon. So I added a bit more magenta to simulate a "red rock country" picture.
