NEW CHDK featuresEdit

long exposuresEdit

• Forum thread: [1]
• The following cameras now has the long exposure possibility, this means: no more limit to 64 seconds, exposure times up to 2000 seconds are available!

a530, a540, a550, a560, a570, a590, a630, a710
g9
ixus70_sd1000, ixus80_sd1100, ixus870_sd880, ixus90_sd790, ixus950_sd850, ixus970_sd890
s3, s5
sx1, sx10, sx200

PTP stuffEdit

• PTP forum thread: [2]
• ewavr's test versions & tools: [3]
• The PTP stuff is available for following cameras:

a480-100b
a540-100b (patch by reyalP, [4])
a590-100e, a590-101b
a610-100e, a610-100f, a650-100d (patch by lauer, [5])

ScriptsEdit

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 TLEdit

• 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 intervalometerEdit

• 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
• last update: 06-Feb-2010/fe50

function InnerLoop()

	TakePicture()
	InnerShots = InnerShots +1
	sleep(Interval1 - (get_tick_count() - StartTick))
end
 
-- MAIN -------------------------------------------------------------------------------------

		InnerLoop()
	end
	OuterShots = OuterShots +1
	print("o:",OuterShots," total:",InnerShots)
	sleep(Interval2 - (get_tick_count() - StartTick))
until false

fast shooterEdit

• 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
• last update: 17-Apr-2010/fe50

--[[
@title fast shooter
@param a Duration, min
@default a 0
@param b ...sec
@default b 20
--]]
Interval = a*60000 + b*1000			-- we need the time value in ms
StartTick = get_tick_count()			-- start time value
press("shoot_half")				-- prepare...
repeat sleep(50) until get_shooting() == true	-- wait until focus is ok
press("shoot_full")				-- start capturing...
sleep(Interval - (get_tick_count() - StartTick))-- wait
release("shoot_full")				-- time is over, release the shutter
release("shoot_half")
