The sky is incredible! Tell me, did you pump up the saturation or are the photos un-retouched?
Ellen, I posted this mobile (you can always tell when I do this because the photos are not embedded in the text, but stacked at the bottom). All I did was resave them in the photo app on the phone to make them smaller.
The sky was incredibly blue, but I'm sure the iphone saturates a little in its processing.
And now that I am home, I redid the images in photoshop (cropping, levels, no saturation). I don't like the way the iphone compresses images, usually blurring them. I see the iphone's processing is a touch more saturated in the blue, and leaned on green a touch too. Can you see the difference?
I notice the difference most in the middle photo, but the blue sky is still gorgeous. Looks like a great spot.
