I've been shooting 35mm slides lately since my darkroom is boxed up. Mainly provia100, which although produces vibrant slides is not very forgiving in some instances. I wish I had a nice light meter, but rely on my camera's meter and in some cases a grey card. I was just curious if any of you can recommend a good method for bracketing slide exposures. I know it depends on the scene, but general advice is fine. I'd like to get to a point where I can bracket around 5 frames and be fairly confident I got the shot. Thanks!
