"I've seen a million years pass right away.

I've seen the gods of yesterday, they're old and grey.

If you will fail, there's only one more way."

What we need right now, is a miracle on earth

Let our hearts cry out, so our voices can be heard

Let us walk away together, from the never ending rain

'Til the sun will shine for all of us again.

GAMMA RAY -- MIRACLE

[edit] Scripts

[edit] unleash Canon TL (Digic III)

With the following little script you can override the Canon time lapse value...
When you run this script, the intervall value will be set to 5 seconds (adjustable in the script menu), this new value is active until you change the value in the Canon menu or until you power off the camera.

→ 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...

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

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