Zoom Bracketing by Johan Van Barel (http://www.vanbarel.com)
The purpose is to create a set of images taken at different zoom positions.
The script takes a number of images starting from the current zoom position. So if you take 3 pictures, with Zoom Step Size 1, the script will take the first picture at the current zoom position, the second at zoom position +1, and the third at zoom position +3 relative to the start zoom position. A positive Zoom Step Size will zoom in, a negative Zoom Step Size will zoom out. Afterwards the initial zoom position will be restored.

Select any mode on your Canon A640 that allows zooming.
- Number of Pics (Default=2)
- Zoom Step Size(+/-) (Default=1)
- Initial Delay (Sec) (Default=1)
