f. Disable (turn off) the flash.
g. Disable (turn off) the AF-Assist Lamp. Usually located near the lens
barrel, an Autofocus Assist Lamp assists focusing when taking photos in
low-light conditions. When the shutter-release button is depressed half-
way, a light beams from the camera to illuminate the area where the
camera is focusing. However, the lamp’s short range is useless for taking
photos from an aircraft. If you are shooting through a closed aircraft
window (you shouldn’t), the lamp may confuse the camera’s focus.
h. Disable (turn off) Digital (electronic) Image Stabilization, unless you know
it’s helpful. This feature, usually a high ISO sensitivity mode, is found in
many compact cameras and is designed for stabilizing hand tremor; it
may not correct for large amounts of wobble resulting from a moving
airplane. More importantly, most of today’s digital image stabilization
technology doesn’t prevent blur if the subject itself is moving (which is the
case when you are shooting from a moving aircraft). Some systems are
better than others: some help, but others may actually make things worse
(increased noise). Try taking photos with the digital stabilization both ON
and OFF to see which works better. If in doubt, turn it off. [Note: This
doesn’t apply to Optical Image Stabilization, whether lenses or sensors.]
i. Check or set photo type, resolution and quality depending on how the
photos will be used. The best choice for the majority of CAP imaging
missions is JPEG with the highest resolution with the best quality. This
results in high-quality, low-compression files of manageable size.
1) Some customers want us to use the RAW photo format.
2) If you know that the customer won’t want to print the photo or
examine the target in great detail, you may choose lower settings. If
you only intend to e-mail the pictures (or the photos are only going to
be viewed on a monitor or posted to a Web page), you can use lesser
quality settings if you don’t want to bother to resize or compress the
photos before they are sent to the customer.
j. If having the shortest time possible between pictures is important, you can
shorten (e.g., by about 0.5 seconds) or deactivate the instant photo
review function that automatically displays the image on the LCD
immediately after it’s taken. This saves time between photos and also
saves your batteries. This can be used in addition to selecting the
camera’s burst (continuous shooting) mode.
k. Set the Diopter Correction. Look at something within shooting range,
raise the camera's viewfinder to your eye, and adjust the diopter until the
scene or the focus brackets are sharp.
