One of my dove photos just hit the first page of popular on 500px. First time any of my photos have gotten quite that far. Given that it was a from-the-hip shot without ANY planning or artistic goals whatsoever, I'm pretty stunned:
UPDATE: Now it's the first image in the second row of the popular page! Pulse is 99.7. I wonder if it will hit the top row before it's pulse is knocked back at 24hrs...
That should help justifying the 600?
Congrats and Good Luck! It's a great image!
