2 Auto exposure
•
Set the camera to Programmed Auto mode (Camera Manual p 45)
and take your photos using this.
•
For more open canopies, over-expose using the exposure
compensation setting (p 44), up to the full +2.0EV for very open
canopies.
•
For more closed canopies, under-expose, up to the full –2.0EV for
mostly closed canopies.
•
If you have sufficient memory, you can try exposure bracketing
(Camera Manual p 107) to take photos with higher and lower
exposures. Examine these when you get back to the lab, and choose
the image that gives the clearest canopy edges.
Taking the Picture
1 Using Timer
•
Press the flash button until the Anytime Flash icon shows (Camera
Manual p 37).
•
Select a 10 or 3 s delay for the self-timer mode by repeatedly
pressing the timer mode button. Check the flash icon is also showing.
•
Press the shutter release and move the camera and SLM into place,
checking it is as level as possible, and pointing to North. Hold it still
until the timer completes.
2 Using the Infrared Remote Control
The infrared receiver is mounted on the lower front right of the camera. It
has a direct line-of sight range of up to 5m except in bright sunlight.
Use of the infrared remote control is
possible using light scattered off the
underside of the self levelling mount and
fisheye lens.
With no modification to the matt black
underside of the Self Levelling Mount we
found the range is about 1-2 m in
overcast conditions.
A simple folded piece of aluminium
kitchen foil or white paper, tucked under
the rods of the counter balance, forming
a rough 8 x 16 cm reflector, doubled the
effective range to 4 m and helped make
the self timer / shot confirmation lamp visible.
