Cute Canon Capture is an open source and free program to control your Canon camera using a USB cable.I haven't tried it personally, but I can see it being extremely useful in certain situations, especially studio product photography.
Cute Canon Capture runs on Windows only (sad) and works on the following Canon camera models:
- PowerShot A620
- PowerShot S80
- PowerShot S3 IS
- PowerShot G7
- PowerShot A640
- PowerShot S5 IS
- PowerShot G9
- PowerShot SX100 IS
- PowerShot G10
- PowerShot SX110 IS
