'Tough' meant it was an uncompromising image, something that came from your gut, out of instinct, raw, of the moment, something that couldn’t be described in any other way. So it was tough. Tough to like, tough to see, tough to make, tough to understand. The tougher they were the more beautiful they became. .
~ Joel Meyerowitz
I assume he only got the one shot, and then made multiple exposures in Photoshop, and then Merged them via HDR?
Or, do you think the photographer took multiple shots live, and then merged them all? I just wonder how that would be done considering these dancers were likely in constant motion.
