For landscape photography with 35mm, I would suggest a slower film. You will, or at least should, be using a tripod anyway, so why not reap the benefits that a slower film has in the 35mm format.Originally Posted by Huram
400 speed would be better suited for your party shooting.
When I was shooting 35mm, my favorite film by far was Tri-x. For slow film, I would suggest one of the Efke's, 100 or 25, available from J&C. Efke is excellent, as is it's price.
