It really depends on what you're into and what you're into photographing. Neighbourhoods like Gastown, Strathcona, and the new Olympic Village will have exquisite architecture. The Skytrain might be neat to ride as well. For hustle and bustle or street photography, Robson St, Granville St (including the main part downtown and South Granville in Kits), and Commercial Drive are safe bets. You can get some great city views from False Creek, Stanley Park, Spanish Banks, and from the SeaBus (goes from Downtown Van to North Van). Iconic architecture would mostly be relegated to Canada Place, the flatiron in Gastown, Living Shangri-La, and the Vancouver Public Library. Vancouver Art Gallery might be worth a visit if that's your thing, as would the Harbour Centre for the observaton deck. What else? There's the Capilano Suspension Bridges, the Golden Gate Bridge, Grouse Mountain, and Stanley Park for more nature-y stuff. Vancouver also has a heavy Asian influence, so you might want to check out Chinatown or Richmond.
