Glossary of Terms
For the sake of clarity, here are short and simple explanations of sev-
eral terms, items and features mentioned in the manual that may be
unfamiliar to some.
Bar code
Some roll film brands have a Bar code which the H1D magazine
can recognize and interpret. is automatically transfers the ISO
rating and film length of the film to the camera and saves you from
an incorrect setting. However, you might wish to rate the film at a
different ISO setting, in which case you should transfer to manual
ISO setting.
Bracketing
e practice of making extra exposures over or under (normally
both) the ‘standard’ exposure to ensure the desired result. is is
particularly useful when using transparency film in difficult lighting
conditions. Easily set and controlled with the H1D.
Browse/Scroll
A computer term refering to the method of searching through stored
digital information, normally accessing the information visually,
controlled by buttons or control wheels (real or digital).
Custom setting
e setting chosen by the user that differs from the default set-
ting.
EV
Exposure Value. It represents the standard photographic notation
within exposure control. For example, if you change the aperture
on a lens from f/11 to f/8, you will increase the exposure by 1EV.
Similarly, if you change the shutter speed from 1/15s to 1/60s you
will decrease the exposure by 2EV. A change in EV can therefore
represent a change in aperture, shutter speed or a mixture of both. It
is a simpler and more useful way of referring to the essential effective
combination when making exposure settings without referring to
the implications and sometimes confusing aspects of specific shutter
speeds or apertures.
As a practical example, if you are using ‘exposure compensation’, the
settings are in EV’s (oen referred to as ‘stops’ in older descriptions)
or fractions of EVs (or ‘stops’). erefore an exposure compensation
of +1EV, for example, will provide ‘one stop overexposure’ and
similarly an exposure compensation of -1/2EV, for example, will
provide ‘ a half stop underexposure’.

aperture/shutter speed equivalents
