I try use a lot of Bounce flash in my shots when I am on event shootings, however lately I am running into a lot of Bright colored walls, High ceilings, or just no good place to bounce. I was thinking about hauling a large white surface with me, and then attach it somehow to a light stand maybe, has anyone ever done or made something like that? ( I know there are expensive pro Reflectors available but the prices are crazy) An artist friend of mine suggested using a large stretched white canvas but those are pretty heavy. Any suggestions would be appreciated.
