Cruisertoy, sorry it has taken me a while to get back to you. I find the computer horribly distracting and therefore don't get on here too much. Every Miles A Memory is pretty close on my timing, but the sun had actually long since set in the canyon, and due to the overcast it was quite dark which is how I got such a long exposure (20sec). That long exposure with extremely soft and even light is how I captured all the colors. I used a 6.0 ND filter on some other shots which helps a lot during the day, but is still no replacement for dawn/dusk lighting.
