Can a Canon EOS 350D or IXUS 100 IS be used for live preview or webcam-style shooting from a computer?

I want to control a camera from a computer and capture photos programmatically. Ideally, I’d like to see a live preview on screen before taking each shot, similar to using the camera as a webcam. I have a Canon EOS 350D and a Canon IXUS 100 IS available, and I’m open to using SDKs, tethered shooting, or third-party firmware if needed. Is this possible with either camera?

Whilst there is support for using the Canon 350D in a tethered mode, with "remote" shooting, there is no control over the zoom other than manual intervention; as that camera does not support video, or even "live view", or wouldn't be able to see how the photograph would look before shooting it -- depending on your scenario, you could just shoot and reshoot if required (for something like taking product shots), or take periodic shots (for something like a weather-watch webcam).

For the IXUS, your chances are better, but you may have to install third party firmware, such as CHDK

The EOS 350D can be used in tethered/remote shooting, but it does not have video or Live View, so it cannot provide a true webcam-like live preview. You can trigger shots from a computer, but framing/focus changes would need to be handled manually, and you’d generally review images after capture.

The IXUS 100 IS is the better candidate. Canon’s compact PowerShot/IXUS models can often be extended with CHDK, which enables extra control and scripting. Based on the answers, CHDK may let you automate shooting, but a live video stream is not guaranteed.

So, in short:

  • Canon 350D: remote shooting possible, no live preview/webcam use.
  • Canon IXUS 100 IS: better chance for scripting/automation via CHDK, but live preview support is uncertain.

If your goal is repeated still captures rather than continuous video, either camera may still work depending on your setup.
