Keith, I like your photos. Especially this one. But I would be scared as hell if I ever saw that colour in the sky. Wouldn't this be a more stunning picture is some of that sky were less contrasty. I might have tried just using 'desaturation' just to take some of the sting out of it. But I do like it. I love clouds and I like the open road.
By the way, I am also a committed 5050 user. I like its size and feel in my hand compared to the 5060, 7070 and 8080.
