In
Large Format Photography
a large camera is used with
extensive possibilities to adjust the image and with a large negative
or
positive sheet of film.
It
looks very old-fashioned,
but these cameras are still
manufactured by firms like Gandolfi, Linhof and Horseman, respectively
from
England, Germany and Japan.
It
is a slow way of making
photographs but has the advantage
of
producing very high-resolution images.
As an example: a 4x5 inch sheet of film, exposed through a modern lens
yields an image of 140 Megapixels (see
example),
while an 8x10 inch sheet of
film offers 600 Megapixels.
Modern
digital cameras are
not ready
for such detail. Apart from the resolution, surfaces and textures are
rendered more smoothly
with a large sheet of film, which can be used in
expressing an overwhelming sense of realism.
Another
advantage is the
image control and deliberate action of taking
a photograph. It is slow, but when you trip the shutter, you
usually
have made many decisions so that in practice the percentage of
successful images is very high compared to that when using
a smaller
camera.

The
two large format cameras
I use are the Linhof Master
Technika 2000(a 4x5 inch camera) and the Gandolfi Variant 8x10.
The focal lengths for the 4x5 camera are 47, 65, 90, 150, 210, 300 and
450 mm. and for the 8x10 camera 150, 240 and 480 mm.
My preferred film is Fuji Provia 100F and Velvia for transparencies and
Kodak Tmax 100 for black and white negatives.
