second for super 8. For video work, the shutter speed
should be set to 1/500 second or higher.
When shooting, you must keep the camera steady,
keep your upper body and the camera from making
contact with the aircraft, and make any necessary pans
slowly and smoothly. Fixed-wing aircraft should make
a gentle arc around the subject (into the wind) at
moderate speed and with a few degrees of flap. On
occasion, you may be filming a fast-moving activity on
the ground. Again, the technique of flying an arc
around the subject is often best because you are moving
faster than the action below. You need a zoom lens or
a camera with a turret and different focal-length lenses
to change your view of the subject. However, avoid the
temptation to overuse the zooming technique while
shooting. Instead, change the focal length between
scenes to obtain variety and interest in your images.
The problem of maintaining a steady image is
greatly magnified when you must shoot with a long
focal-length lens. In these circumstances, you should
use a gyrostabilizer, if it is available. A gyrostabilizer
is an aerial camera mount that uses a gyroscope to
maintain camera stability.
PROCESSING AERIAL FILM
Because of the cost involved, the importance or
urgency of the images, and the situations involved in
obtaining aerial images, it is extremely important to
process images under optimum conditions and the
images be free of physical or chemical defects.
Film processors must be checked and verified
according to the quality-assurance procedures
established by your imaging facility. Processing
solutions, machine speeds, and temperatures must be
checked with sensitometric tests and verifed to comply
with the processing instructions indicated on the
mission planning form. Each aerial film-processing
work center should have an established family of curves
for each type of film used. Camera exposure settings
are based on the expected response (speed) of a
particular emulsion developed to a specified gamma in
a particular type of chemistry at a specified temperature.
If you deviate from the planned processing parameters,
it affects the degree of development of the imagery and
may render the imagery unusable. The photo
processing crew is the key to success or failure of the
entire reconnaissance mission.
MISSION PLANNING FORM
TARPS. It is a tool of communication between the
reconnaissance coordinator, squadron maintenance
personnel, and imaging facility personnel. The form is
divided into three basic areas of responsibility: mission
data, maintenance, and processing data. The section of
primary interest to you is the mission data and
processing data.
Mission Data Section
After reconnaissance mission requirements are
established, the sensor or group of sensors best suited
to fulfill the requirements are selected. The mission
planner should enter the sensors, the appropriate sensor
IDS, the types of film, and the processing gamma of the
types of film. The mission planning form should then
be forwarded to the aircraft maintenance personnel and
to the photo personnel. This data may then be used to
equip the aircraft for the mission. The data also allows
the imaging facility to make preparations for processing
the film.
Maintenance Section
After receiving the mission planning form, the line
maintenance personnel begin preparing the sensors,
associated equipment, and aircraft for the mission. As
various tasks are completed, the Maintenance section of
the form is completed by maintenance personnel.
When the aircraft returns from the mission, the film is
removed, and the appropriate postflight counter settings
are entered in the Maintenance section of the form by
maintenance personnel. The film, along with the
mission planning form, is then delivered to the imaging
facility for processing.
Processing Data Section
The film is processed according to the information
entered in the Mission Data section of the form. The
film processing results are entered in the Processing
Data section of the form. The film is then evaluated for
image quality and appropriate entries are also made in
the Processing Data section of the form. Finally, the
completed mission planning form is returned to the
reconnaissance coordinator for purposes of debriefing
and filing.
