Scripts

These scripts or script fragments are samples from my private collection; they are tested for my privat purposes only !

They may or may not work on other cameras - use them on your own risk !

unleash Canon TL

only for Digic III cameras with internal time lapse video feature, like the SD870
With this script you can override the Canon time lapse value...
The interval value is set to 5 seconds by default, adjustable in the script menu;
this will be active until the value is changed in the Canon menu or until the camera is powered off.
Just load the script, set the time you want & start it with the shutter button;
then leave <Alt> mode and make your time lapse or whatever else you want to do...
tested on: SD870
last update: 06-Feb-2010/fe50

You can also set other propcases with this script; DO NOT change the first parameter (propid, default value is 165) until you exactly know what you are doing !

rem override Canon interval, Digic III prop165, value in ms
@title set tl propcase
@param a propid
@default a 165
@param b new value in s
@default b 5
@param d propcase factor
@default d 1000
 
b = b * d
get_prop a c
print "Old value : " , c
set_prop a b 
print "Now set to: " , b
sleep 2000
end

double intervalometer

simple Lua intervalometer with adjustable shot count
inner loop: takes x shots in the given interval
outer loop: runs inner loop in the given interval
works with "old style" shutter button emulation instead of shoot(), should work on all cameras, also on older Ixus models, OS and image processor shouldn't matter
tested with: SD400, SD870, SX10

	end
	OuterShots = OuterShots +1

	sleep(Interval2 - (get_tick_count() - StartTick))
until false

fast shooter

simple duration shooter script
this script simply holds (virtualy, of course) the shutter button down for a while...
useful for fast & unlimited bracketing in continuous mode:
- set up CHDK bracketing, e.g. [+/-] bracketing with [2/3 Ev] steps
- set the camera to continuous mode (or AF cont. mode), set up the camera for your needs (e.g. camera mode, ISO, focus, flash ...)
- load & run the script (adjust the Duration in the script menu to your needs)
tested with: SX10
