Duplication work and photomicrography
In copy work, slide duplication, and photomicrography, you
cannot obtain correct exposure by simply referring to the FM2's
exposure meter display because these types of photography
represent unusual contrast situations. Exposure compensation
is required. Shown here is the table of the relationship between
specific photo types and proper exposure. Since this is meant
to be a guide, in practice you should make further, compensation
by experimentation until you achieveIthe proper results.
• The exposure compensation values listed below are reference
data obtained when general-purpose film was used. With color
reversal film or microfilm for duplication work, It is advisable to
take additional shots with ± one-stop exposure compensation
as these films have very small exposure latitude.
’ To avoid vibration, you can make the exposure by turning the
illumination on and off.
' It is advisable to use a cable release to avoid camera vibration.

For high-contrast subjects, use of an 18%
reflectance gray card in determining exposure
is recommended. With the card, no exposure
compensation is required regardless of whether
the background is black or white.

Generally, results come out better with more
exposure in photomicrography. The compen­
sation value on the left is only a guide; determine
the compensation value by test shooting.
