Aperture aggregates the best posts from this past week in the photography blogosphere.

• Time’s Lightbox profiles ‘Act’: Meditations on the Disabled Body by Denis Darzacq, a two-year project of photographing “people who have had trouble finding a place in society from the beginning of their lives,” he says. The Paris-based photographer known for his high-energy images and dynamic subjects will be giving an artist talk at Aperture this Monday, April 16, 2012 at 6:30 pm, FREE.
• Kathy Ryan, editor of The New York Times Magazine Photographs, shares the fascinating backstory of a photograph of Mohammad Ali with his future wife Lonnie that ran in the Sunday Magazine, taken at “the moment Cassius and I met,”  Lonnie wrote in an email to the photographer, Steve Schapiro.
• The New Yorker‘s photo department shares a collection of reader-submitted, “Hand-Picked Instagrams,” (as Wall Street Journal did last week, and more publications probably will in the future) alongside a thought-provoking essay by Ian Crouch, “Instagram’s Instant Nostalgia.” This, in the same week New York Times’ Bits Blog reports Facebook will buy Instagram for $1 billion.
• The British Journal of Photography reports on a controversial ad campaign for photographers’ rights launched by the French organization Union des Photographes Professionnels – Auteurs. In related news this week, the American Society of Media Photographers has filed a class action lawsuit against Google, PetaPixel reports, for “scanning, indexing, and storing copyright work without permission of the copyright holders” for their ambitions Google Books project.
• DIY gallerists take note: Phototuts+ shares “An Expert Guide to Matting and Framing a Photo,” which should be useful after you’ve watched their video lecture on Ansel Adams–delivered by Allan Ross who was Adams’ darkroom assistant for many years–and printed a bunch of restrained, expertly metered black-and-white landscape photographs of your own.
• American Suburb X shares a number of Nan Goldin readings this week, including an essay by Nan on actress and close friend Cookie Mueller who died of AIDS in 1989, as well as a fascinating in-depth paper by Mihaela Precup, “The Wound Which Speaks of Unremembered Time: Nan Goldin’s Cookie Portfolio and the Autobiographics of Mourning.” All great reads; our only quibble is: where did they come from? [UPDATE: ASX has appended the source of one of the pieces, created originally by Dirck Halstead at the once-pioneering web journal digitaljournalist.org]
• The John Simon Guggenheim Memorial Foundation announce their 2012 Fellowships in photography, PDN Pulse reports. Ten photographers, including Doug Dubois of the monograph All the Days and Nights, and John Gossage, whose exhibition The Pond and a Little Romance opens today in Chicago, join the ranks of past recipients Robert Frank, Diane Arbus, Robert Adams, Richard Mosse, Brian Ulrich, and Penelope Umbrico.
