Last week in Barcelona, American photographer Spencer Tunick gathered 7000 naked strangers (registration required) who had volunteered to participate in his latest mass nude performance/installation, Nude Adrift. Photographing his subjects from above using an elevated platform, Tunick took three pictures of the crowd: one of them lying on their backs, another kneeling with their bottoms in the air and a third of couples embracing. The Barcelona event, which broke the world record for the largest nude photo shoot, continues his documentation of live nude figure group performances. Previous cities include Montreal, Prague, St Petersburg, Tokyo, Cape Town, Santiago, Helsinki and New York.

Digital Camera Resource Page has posted a full review of the new Canon Powershot G5 digital camera, noting several pros (excellent photo quality in most situations, super fast performance, 4x zoom a nice change from the usual 3x zoom, CompactFlash Type II slot, impressive movie & playback modes, has an AF illuminator lamp, FlexiZone focusing system lets you focus on any area of frame) and cons (redeye worse than expected, too much purple fringing, lens blocks view through optical viewfinder at wide-angle setting). There's also a first look review up on Steve's Digicams now (via PhotographyBLOG).
