Repro-Copying
For originals such as photographs which have tonal gradations, exposure is determined in the usual way.
In the case of originals having strong contrast and no gradation, such as documents or line drawings, measure the
brightness of the white portion of the original (if the original is predominantly black, a sheet of white paper may be
substituted) after decreasing the film speed by four marks. Or open up the lens about 1-1/3 stops.
Slide Copying
For originals with continuous tonal gradationS, determine exposure in the usual way by the stop-down method. To
copy slides with letters or figures on a transparent background, decrease the film speed four marks, or open up the
lens about 1-1/3 stops. In the case of transparent figures or letters on a dark background, either increase the film
speed five marks or stop down the lens about 1-2/3 stops.
Important: The above are only approximate guidelines. Exact exposure determination is extremely difficult, espe-
cially with reversal color films. Therefore, it is advisable to make several dffferent exposures for each subject to be
sure of getting one that is correct.
Fisheye-Nikkor Auto 8mm f/2.8
Because of its wide picture angle (180
°
), the Fisheye-Nikkor is susceptible to inflated exposure readings due to
direct sunlight. To compensate, open up the lens two stops.
