User Manual - Snap Studios

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 main screen and save the new setting
at the same time.
Roll film
The H2 uses two sizes of roll film (120 and 220) that has different
lengths. 120 film generally produces 16 exposures per film and 220
film produces 32 exposures per film. (‘Half-length 120’ film also
exists that will produce 8 exposures per film. This though has a
very limited availability).
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. The spool
left 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, exposed or unexposed, as indelible marks can sometimes be
caused. Please note any special conditions or restrictions regarding
airport security x-ray devices or similar as they can potentially
damage film (by fogging) in some cases.
Standard exposure
A ‘standard exposure’ in the manual refers to the concept of
technically correct in accordance with internationally accepted
photographic measurement standards (see section on Mid-grey /
18% grey). This does not imply, however, that it would automatically
be the preferred choice or be ‘correct’ according to the desired
result. See section on Bracketing.
Main screen
To simplify the descriptions, reference is often 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.
The ‘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).
TTL
Through The Lens - a literal description of the light measurement
mechanics. The advantage is that only the essential parts of the
subject in front of the camera are included. Accessories such as
filters, bellows, close-up rings, converters, etc that could affect
82
exposure are also taken into account automatically with exposure
evaluation (for general purposes).
Time out
This is the time interval that a temporary setting is maintained
for before it automatically returns to the original setting (default
or custom).
Toggle function
If a button has a ‘toggle function’, it has the ability to access two
separate states simply by being pressed again. On the magazine,
for example, if you want to change the data setting from ‘on’ to
‘off’, you would start by pressing the function selector twice to
access the film length setting. Then, to change from ‘on’ you can
press either the ‘change up’ or ‘change down’ button as both buttons
have a ‘toggle’ function. By pressing the same button again
therefore, the setting will revert. This means you do not have to
remember which button to press as they will both produce the
same desired result in this case.
Zone (system)
The Zone System is a method of combined exposure calculation/
film development providing a great deal of tonal control. It was
originally devised by Ansel Adams - the classic landscape photographer
and Hasselblad user - and now exists in various forms for
both black & white and colour photography. An integral part of
the method includes the classification and grouping of any given
scene into a range of nine (or ten) so-called zones, hence the name.
The method produces a great degree of result predictability and
image tone control.
Concerning the H2, the word zone refers to the grouping and
classification of various tones, where Zone V is the equivalent
(whether in black & white or colour) to 18% mid-grey on a scale
of Zone I (black) through Zone IX (white). See specific literature
for a complete description of this method.
