The REPROattachmentfor the exposuremeter is
designedto give you proper exposureinformation
when photographingflat copy such as paintings,
documents,prints etc. The combinationexposure
meter+REPROwill also permitcheckingthe uni-
formityof the illumination.
Attachingthe REPRO is quite simple: slide the
hemisphericaldiffusorof the exposuremeterto the
right so that it will fit into the cavity of the attach-
ment.
Insertthe lug (53) of the REPROintothe slot at the
top of the meter housing.While pressingthe lock-
ing knob (52) slide the attachmentflush onto the
meter (the diffusorof the meter fits into the recess
of the adaptor).Releasingthe locking knob will
