Thanks for commenting. It is digital. This was shot on a pretty dull day with broken overcast. I used some channel blending and LAB moves to improve the detail and color. I am pretty sure I pushed the sky to a bluer shade. I tried not to go overboard. I will take another look at the sky and see what I left behind. The Portland area is pretty special with mountains, forest, rivers, ocean and high desert all within a couple of hours.
