I have just started using CHDK for a week now and I am too excited about it.
I wanted to click on specific type of pic where I wanted

A small zoom motor operation when the shutter is open to create radial motion blur.

Is it possible with the CHDK script and SX130IS.

Thanks in Advance.

Thanks for pointing in that direction

I tried the script BUT could not get it working.
I am using SX130IS and this is what happens:

After shutter opens zoom operation starts
and camera stops All the LEDs goes blank and I need to
power on the camera.

I am still trying with various settings but no luck.
Can anyone help if he/she have successfully done this on SX130IS

Thanks in advance

I tried on sx130  but without significant results. I had exactly the same problem - camera crashes. I haven't found a reason.

I have also tired focus changes during exposure and this works without any problems.
