Photo Equipment: Good digital Cameras or your DVs! You can get some many good shots in Vancouver easily. During our 10 days trip to Vancouver in year 2000, we finished 10 rolls of films (including 24s and 36s). Imagine how much that cost after we developed them! Make sure you bring extra batteries for your DV cameras or CamCorders when you come in the winter. When I was here in November, 1998. Our battery only lasted 10 mins outdoor coz it was fricking cold....
Raingear!!! Vancouver is by far Canada's wettest city on the West Coast. Dry spells are rarer than showers. Asking Vancouverites whether they mind their moist climate, the answer is more than likely to be 'It is a hell of a lot better then -40C and 3ft of snow!'
Photo Equipment: A good camera with at least 1 wide-angle and 1 zoom lens. For taking pictures at dusk and dawn, a tripod is also highly recommendable.
I used following gear: Nikon F50
Kodak ISO-100 film
Miscellaneous: For non-american travellers: proper 110V convertor plugs
Photo Equipment: British Columbia is great for picture taking. You can gets some great pictures if you're patient and know a thing or two about photography. Some of the greatest pictures of Vancouver that I've taken and developed are of nature and scenery. British Columbia contains several animals out in the wild as your subject. If you're into rock climbing, then you can take pictures from the tops of hills and mountains.
