taken from the camera, many amateurs are likely
to take the cartridge in the hand and wind it as

injure the negative than this tight drawing of
the film, as it abrades the surface, makip.g fine
parallel scratches running limgthwise of the film,

to be wound tightly enough so that duplex paper
keeps inside the flanges. ,
