Subject: Fw: [Leica] Speedier Rewind of screwmount, M3 & M2...

Speedy rewind of film into the cassettes may not be in anyone's best
interest due to static electricity injury to the images on the film.

Back in the late 1950's, Life Magazine was wrestling with a problem of
static electricity exposure to 35mm negatives coming from Leica screw mount
cameras.  They concluded that the cause was rapid rewinding of the film into
an ungrounded camera body.

I recall that they cautioned their photographers to slow down on their
rewinding of the film and, when possible, to ground the camera body against
metal while rewinding.

I have used screw mount Leicas on and off since 1957 and have adopted an
unhurried pace for rewinding the film, experiencing no problem.
