Re: Re: Slit-apertures ?

Eric says that the "traditional' positioning of the two slits is two inches
apart and the one nearest to the film two inches from the fil. The slits
work well if about 1/50 inch in width. I saw somewhere that you should be
able to slide a sheet of photographic paper through the slit. there's an
awful lot of room for experimentation with this.
