Default setting / factory setting
A standard setting that a device is set to in the first instance during
manufacture and returns to if a setting change is halted or inter-
rupted in any way.
Half-press
Some actions are initiated by pressing the shutter release button half
way down. For example, the auto focus and light metering are both
activated by a ‘half-press’.
Histogram
In the case of digital cameras (and digital-image computer soware),
a histogram is a graphic representation of the range of tones from
dark to light in an image measured over two axes.
LCD
Liquid Crystal Display. An electronic information panel. e grip
and magazine both have LCD panels.
LED
Light Emitting Diode. Electronic devices used in information dis-
plays. e viewfinder display has LED’s to the le and right of the
integral LCD panel.
Mid-grey / 18% grey
An important point to be remembered is that all photographic
exposure meters / light metering systems are calibrated to provide
a reading that will reproduce a ‘mid-grey or 18% grey tone’ from
the measured subject tone. is is an international photographic
standard upon which all exposure calculations must be based. e
H1D has very accurate and sophisticated exposure measuring modes.
Pre-programmed information is taken into account via the metering
system when calculations are automatically made. is provides a
very satisfactory compromise for a host of photographic situations
and many users will certainly be very satisfied with the consistently
high quality of results. Nevertheless, some situations are either so
technically difficult or open to interpretation that manual interven-
tion is advised to ensure the desired result. Naturally, many seasoned
users always prefer manual control but they base their calculations
and decisions on much experience.
To illustrate this point, imagine the following example:
Pin two sheets of paper, one black and the other white, onto a grey
wall. Take three exposures using an average light reading; a close-up
of the black sheet, a close-up of the white sheet, and a distance shot of
the whole wall including the two sheets. Without any manipulation,
the first two exposures will produce a tone that is similar to the wall,
namely, a grey tone; not black or white. e third exposure, however,
will reproduce the wall as a grey tone while the two respective sheets
