- Which cameras?
- On the cradles for aerial photography,
there can be installed:
- the film cameras,
- the digital cameras,
- the camcorders.
- The film
cameras have a quality/cost
ratio still unequalled.
- The digital
cameras are inexorably increasing
photographic definition and reproduction of colors. To get
the image quality of a film camera, the it must be turned
on the top models, with expensive prices. On the other hand,
some cheap digital cameras with fix lens gives the opportunity
to start kaping at minimum cost with some other interesting
- A camcorder needs ideal flight
conditions, and a cradle with perfect stabilization. Its
use is thus rather not frequent.
- Compare the lenses by their
focal length is rather impossible as there are now so many
- The most practical way is to use
the angular field.
How to choose?
For each category
of camera I have indicated the applicable criteria for a
kap use. Moreover, hereafter are the principles to which
I'm personally keen:
no camera have a plug for electric shutter release. One
must be installed. The advantage of this system is first
its great reliability, and, second, the possibility to install
easily different cameras on the same cradle, without to
be obliged to make consistent modifications.
When a photograph
is successfully done, I wish to enlarge it to a 30x40cm
at least. Besides, the reproduction of colors, the clearness
of shadows, the accuracy of details, the lack of vignetting
effect are necessary for me.
In kap practice,
as in sport photography, it is peremptory to catch the instant,
and a camera which let spend some valuable fractions of
seconds before to fire is not suitable.
Lock the focus is an
important con'. However, be suspicious on cameras which do not
set the lens in position before but only memorize it, and then
action the lens motor when released, thus loosing valuable fractions
of seconds! As example, the Leica Minilux.
Some cheap digital cameras
with fix lens have a sufficient quality to start with. It is
rather easy to install an electric shutter release. The digital
camera let verify immediately after the shot if the orientation
is correct. Then, a good film camera will let shot good
quality pictures with a modest investment .
