FILM
Well, what is there to say. There is little point buying a
camera, plus extras, if you don't use plenty of film.
Most 35 mm film types are also available in 120 roll, but there
is not such a wide range of manufacturers types. That is because
many colour print films in 35 mm. are made by the SAME
manufacturer, despite what it says on the box.
For example, 'Made in Japan' may mean the film is Konica,
regardless of the box name.
FILM SPEED - Film sensitivity to light is known as it's 'SPEED'.
This is measured in an arbitrary range called ISO - International
Standards Organisation. Film speeds are the same for all types of
film. Thus ISO 400 black and white has exactly the same
sensitivity as ISO 400 colour slide.
I general, slow films give fine grain, sharpest results and the
highest contrast. Fast films are the opposite. The only real
exception is, currently, Ilford XP2 mono film which uses colour
technology to produce fine grain at ISO 400.
50 ISO is slow, 100 - 200 is medium and 400 - 400+ is fast. Chose
film to suit the subject and lighting. If you only shoot
enprints, ISO 400 will let you shoot in all types of lighting
with passable results, but ISO 100 is considered by most to be
the best general purpose speed.
COLOUR PRINT - There are a vast range available. I use Kodak or
Fuji if I'm shooting something really important, such as a
wedding. I have also used cheap 'Store Brand' films for family
shots with excellent results. Processing also matters. I pay for
the best for weddings, but, equally have had excellent results
from cheap postal services for home purposes.
You must find a good film and processor, then stick to them.
Colour print is the most widely used film type. Home processing
is becoming easier and more affordable but remains time
intensive.
BLACK AND WHITE - still popular amongst many keen amateurs and
quite a few pros. I still think a well printed mono takes some
beating on the exhibition wall ! The other advantage is that a
darkroom can be set up quite easily nd cheaply. The resulting
prints are then truly your own.
TRANSPARENCY - available in colour and mono, but mostly colour.
Whilst it is slowly changing, slides are still most widely
accepted for publishing purposes. Slow slide film, projected to a
large size can be stunning and will beat prints for impact any
time.
Slide film can be bought with processing included, or excluded
for 35 mm. 120 roll does not have processing included. If you
intend to sell to magazines and libraries, 120 roll is the
favourite, but processing and mounts, both extra, push the cost
to about 50 pence per final shot on average. You tend not to
waste film if you can help it !
