Last night, many Shooting Challenge participants were rejected when submitting their light painting photos to email@example.com. We've now fixed the issue, but to make sure we have everyone's entry, please resubmit your photo. (And for anyone who didn't have time to participate, here's the challenge one more time...you still have a shot to get something in. Frankly, we have relatively low participation this time so it's a good opportunity to highlight your work.) We'll give this to 8am eastern time tomorrow (July 20th). And our apologies for the technical difficulties. When hundreds of people are attaching 6MB files to emails every week, apparently mailboxes can fill up quickly!
