Summer always sees the return of the citys many beloved events and the 12×12 Vancouver Photo Marathon is one of them. Its back Aug. 31 for another exhilarating round of creative challenges that is sure to inspire those driven by photography. A 35mm camera being the only requirement, recreational and professional photographers will each be assigned a 12-exposure roll of film (yes, film!). Beginning at 10am and at the top of every hour for the next 12 hours, a theme will be randomly drawn and released (pictured). At 10pm, only completed rolls will move on to the final phase of the challenge. Negatives will be developed and judged after the marathon, the results of which will be showcased at a free public exhibit with more than 700 photos on display. Tickets ($36 + fee) must be purchased in advance and include film. This year sold out in about one minute, but there IS a waitlist for late-release tickets. Home base is JJ Bean at 2206 Commercial; those on the waitlist who show up on marathon day take priority.
