now appear as black and white respectively, as originally observed.
However confusing this might at first seem, it is fundamental to
mastering exposure calculations and exposure control. If you are at
all unsure about this basic concept, you are strongly recommended
to refer to a general photographic manual for a fuller explanation in
order to obtain the maximum from your H1D.
OTF
Off e Film - a literal description of the light measurement mechan-
ics regarding flash exposure measurement.
Profile
You can programme the H1D by the user to follow pre-determined
‘profiles’. ese profiles are combinations of modes, methods and
settings (custom or default) that suit specific photographic situa-
tions. By using a personal profile - which you can create, name and
save - the camera is immediately configured for a specific purpose
without any need to check through the menus. is is a very rapid
and secure way of working when repeatedly confronted with similar
photographic situations.
As an example you might regularly take outdoor portraits of wedding
couples with a long lens. You want a specific aperture to restrict depth-
of-field and a fairly fast shutter speed to freeze any movement. You are
concerned about the couple blinking during the exposure and so want
to take several shots in succession, possibly with slight variations in
exposure settings for safety’s sake so you might choose the bracketing
option too. All these parameters can be preset and stored as a profile
that is rapidly accessible.
Quick save
When altering settings, a half-press of the shutter release button
will cause a return to the standard screen and save the new setting
at the same time.
Roll film
e H1D uses two sizes of roll film that has different lengths; 120 and
220. 120 film generally produces 16 exposures per film and 220 film
produces 32 exposures per film. ( ‘Half-length 120’ film, that has a
very limited availability, will produce 8 exposures per film).
120 film is supplied on a spool complete with a paper backing that
runs the full length of the film and extends beyond both ends. 220
film, on the other hand, just has paper at each end. In both cases, the
film is gradually transported in the magazine from its original spool
onto another so called take-up spool. e spool le empty then acts
as the next take-up spool for the following film, and so on.
Care should always be taken in loading, unloading, and general
storage. Try to avoid direct light sources when handling film in any
way, in particular strong sunlight. Exposed film should be stored
in dry and preferably light-tight conditions, and developed as soon
as possible. Also avoid any sharp objects pressing against the film,
