You can then full-press the shutter and get much better response times (just like you can do by hand).

That said, I think this project is useful for a lot of applications. For instance if your camera is set to a wide angle and you want to take a picture of people walking through a room this should work fine. Nice article.

the motion detection scripts would probably be faster for this

You’ll notice the autofocus light come on as soon as he breaks the beam. That’s just how long the camera takes to take a picture. Maybe if he used chdk to manual focus it could be quicker but it’s not the trigger that’s causing the lag.
