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 H2F 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 satised with
the consistently high quality of results. Nevertheless, some situ-
ations are either so technically dicult or open to interpretation
that manual intervention 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 rst 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 now appear as black and white
respectively, as originally observed.
However confusing this might at rst 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 H2F.
LED
Light Emitting Diode. Electronic devices used in information
displays. e viewnder display has LED’s to the le and right of
the integral LCD panel.
LCD
Liquid Crystal Display. An electronic information panel. e grip
and magazine both have LCD panels.
Half-press / Full press – Shutter release button
e shutter release button can be depressed in two dierent ways.
is distinction is referred to in the text as half-press and full-press
positions. A half-press is a rapid, so press whereas a full-press is
a rmer and longer depression of the button.
Default setting / factory setting
A standard setting that a device is set to in the rst instance dur-
ing manufacture and returns to if a setting change is halted or
interrupted in any way.
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
eective combination when making exposure settings without
referring to the implications and sometimes confusing aspects of
specic shutter speeds or apertures.
As a practical example, if you are using ‘exposure compensation’,
the settings are in EV’s (oen referred to as ‘stops’ in older de-
scriptions) or fractions of EVs (or ‘stops’). erefore an exposure
compensation of +1EV, for example, will provide ‘one stop over-
exposure’ and similarly an exposure compensation of -1/2EV, for
example, will provide ‘ a half stop underexposure’.
See the chart in this manual for cross reference of EVs and their
aperture/shutter speed equivalents
Click / Press – On.O button
e ON.OFF button can be depressed in two dierent ways which
in turn cause dierent results. is distinction is referred to in the
text as clicking and pressing. Clicking is a very rapid depressing of
the button with immediate release whereas pressing is a longer
depression of the button with maintained pressure.
Custom setting
e setting chosen by the user that diers from the default set-
ting.
Bracketing
e practice of making extra exposures over or under (normally
both) the ‘standard’ exposure to ensure the desired result. is is
particularly useful in dicult, wide-ranging lighting conditions.
Easily set and controlled with the H2F.
Glossary of Terms
For the sake of clarity, here are short and simple explanations of several
terms, items and features mentioned in the manual that may be unfamil-
iar to some.
OTF
O e Film - the literal description of the light measurement
mechanics regarding ash exposure measurement.
Main screen
To simplify the descriptions, reference is oen made to a ‘main’
screen regarding the menu. Apart from default settings, there is no
standard setting in the normal sense and therefore you create your
own ‘standard’, which of course can be changed at any time.
e ‘main’ screen is therefore the one you have currently created
and is the one visible on the LCD when photographing (except
where a particular mode is in actual operation, such as self-timer,
for example).
