The Script Menu

Running a Script - Exposure Bracketing

The CHDK allows you to automate your camera by running "scripts", small and simple programs written in a short-hand version of BASIC. There are scripts for exposure bracketing, intervalometer and many more.

How to run a script:

• Download or write your own script and place it in the /SCRIPTS/ folder of your SD-card.
• Enter the script menu, load the script, adjust the parameters to your liking and leave the menu.
• While still in <ALT> mode just press the [shutter] button and the script will start. A mini console will be displayed while you run the script.
  

• Note 1: It's best to turn off Review in the normal camera menu. Other settings like "x sec" or "hold" can interfere with the execution of scripts.
• Note 2: S3 Users should hold down the [Flash] button (top-left of flash-unit) before pressing the shutter-button when in <ALT> mode or doing so will change your Shortcut option just before executing the script.

• You may interrupt a running script by just pressing the [shutter] button again.
