There’s still room in our exclusive Gargoyles and Gutters tour on the eaves of the National Cathedral on September 10. Sign up, get your $15 ticket for the concert plus local beer, and enjoy an Exposed exhibit of music themed photographs in the concert hall.

• The incredible discovery of a galaxy that’s made of 99.9% dark matter was made by the Dragonfly array–which is just a bunch of 400mm Canon telephoto cameras strapped together to function like a dragonfly’s compound eye. Nautilus had a nice feature from January on how the team came up with idea to study objects that the big, multi-million dollar observatories couldn’t see well.
• Follow the new Instagram account for Air & Space / Smithsonian magazine, @airspacemag, run by our own Heather Goss at her day job. Right now you’ll find the best entries from last year’s photo contest; soon it’ll feature take-overs by some of the best aviation and astro photographers out there.
• Tonight, see work by Exposed alum Lisa Allen along with other photographers and artists at the First Friday reception at Studio Gallery, 6 to 8 p.m.
• “Previously, the only method to enlarge images was moving the phone closer to your face.” Instagram finally adds a zoom feature.
• Woman offers media more flattering photo to replace mugshots after Sydney jailbreak.
• If the lead photo doesn’t suck you into reading this interview with photographer Randy Olsen, we don’t even know what to tell you.
• Dream job alerts: The New York Times is looking for photo editors in their London and Hong Kong offices.
• The Leipzig apartment featured in Robert Capa’s gruesome and unforgettable war photographs has been restored to its former glory.
• Photo Ops: You no longer have to travel all the way out to Shenandoah to get your engagement pics (or whatever) taken at Foamhenge. The artist who built and maintained the parody site moved it this week right to our D.C. suburbs on a hillside in Centreville.
• Photos of “a flood of Venezuelans” taking to the streets to demand a recall election of President Nicolas Maduro amidst the collapsing economy.
• Sorry photographers: We loved your images of the infamous “SEX BARBERSHOP” sign on H street as much as you’ve like taking them for the last five years, but an outgoing Councilmember has decided to ruin our fun.

We’re hosting a fantastic event with the National Cathedral on September 10. Sign up here to get an exclusive tour around the roof eaves of the building, with an incredible view of the city and a close-up look at the gargoyles. You’ll need to buy a ticket for the concert that evening with singer-songwriter Sarah Borges & The Broken Singles for $15, which includes a free beer from Port City and Right Proper Brewing. It’s going to be a super fun night, so we hope you’ll join us.

Want to be a part of the exhibit we’re curating for the concert hall? If you have any music-themed photographs from around the D.C. metro area–concerts, street buskers, an amazing still-life of your guitar collection–tag them with #ExposedMusic and put them in our Flickr group or on Instagram by August 27 (it’s rolling, so the sooner the better). We’ll let you know if we pick your photo, we’ll print it and hang it in the National Cathedral, and you can take it home when the exhibit is over.
