The subroutine fmode checks the current flash mode. If it is not the desired
flash mode (passed in transfer variable M), it fires the necessary key presses
to advance to the next item in the flash menu (section 5.1):
:fmode
r = get_flash_mode
while r <> M
click "right"
click "right"
click "set"
r = get_flash_mode
wend
return
The subroutine prep is used to wait until the camera is ready to shoot—i.e.,
until the command get_shooting returns 1. The subroutine wait works the
other way around; it waits until the camera has processed the current shot:
:prep
do
r = get_shooting
until r = 1
return
:wait
do
r = get_shooting
until r = 0
return
A few words are necessary about script usage. First, cameras that support
manual focusing must be switched to manual focusing mode. For other
cameras, no action is required.
If your camera has a diaphragm, you should use an aperture two f-stops
behind the open aperture. This will increase the DOF for each shot and thus
reduce the number of shots that need to be taken. When shooting with a
fully open aperture (and this is always the case for cameras that have only
an ND filter), a large number of images might be necessary to cover the
