I'm getting continually blotched (not sure how else to describe it) skies with my iPhone 6 camera. They aren't totally blown-out (which I wouldn't mind, because I like the all-white sky look) but this horrid Blue-Teal-White mixture. I took these shots today and tried to fix this problem using the Exposure tool and also tried HDR mode, but nothing helped. An all blue sky would be fine. A totally blown-out white sky would be fine (preferable for me). But a horrid mixture like this ruins my photos completely. Any help?
