… Wobble 2.0 …

I have improved the Focus Wobble script for my Canon A640. Thanks to PhyrePhox over on the CHDK forum, I can actually pull random numbers based on the system clock (at least I think that’s where they are from..).

Here is the new and improved script:

@title Focus Wobble
@param a Focus wobble +/- (mm)
@default a 50
@param b # of frames
@default b 48
a=a*2

get_focus f
print “Current focus “,f,”mm”
sleep 2000
g=f
for s = 1 to b
random z
x=z%(a)
g=f-(a/2)+x
if g<0 then let g=0 set_focus g print "Shot ",s," focus ",g,"mm" shoot next s

I tested it out today. The wobble was set at +/- 50mm which is pretty drastic at such close range. I might also modify it to hold in a certain random zone for a few frames so it is less jarring. Maybe I’ll have it slide around a certain value for a while.

Or maybe I’ll just keep it as is!

I’ve also started working a script I’m calling “Time Bandit” that allows you to shoot time lapse based on how long the event is, how long your final movie will be, and your frame rate.
