Walking around San Francisco yesterday, all I had with my was my iPhone (kicking myself). We went to Pier 39 for the touristy stuff. I could only imagine the HDR shots I could have tried. My 6D will be with me the rest of the time now.
Of course I snagged a couple wing shots too, and a silhouette shot inside the MSP airport. These are all edited with Snapseed on my iPhone 5 the plane and airport shots where taken with my 6D and wifi transfer to my iPhone.
