    I was wondering if any of you inventive guys (or girls) have managed to work out how to extend the bulb exposure on the XPAN I from the maximum 4 1/2 minutes??
    Up to an hour would be good but anything extra would be a bonus.
    This is for night photography on ISO 400 film.
    Many thanks.
