You could tell me this was taken from an altitude of 50 feet or 1000 feet and either way I might believe it. Surprisingly hard to get a sense of distance here, though my guess is it's closer to 1000 feet. Nice capture and a well-balanced exposure.
Thanks for all the comments. The only problem with flying a drone is how easy it is to change your position and angle - I find myself wanting to shoot it all! This is a pano shot RAW, manually, with the standard lens on my MP4, stitched in ACR and converted to B&W there.
