Use of the dark cloth

I suppose a good way to test this would be to sacrifice a sheet of film, load it into the camera and pull the dark slide. Either leave it in direct sunlight for ten minutes or so, or spend some time passing a powerful flashlight around every crevasse of the camera and film holder. Develop the film to see if theres anything other than a blank negative.

Oh no, don't sacrifice a sheet of film for this. A cheap piece of enlarging paper cut to size to fit the holder will work just fine for this test. Trust me. I check my holders regularly like this using the cheapest paper I can find.

I wouldn't sew weights into a dark cloth! I have one that came that way and when it gets windy they can blow around and break the GG or damage the lens. Don't ask me how I know these things, but I have seen it happen.
