ACID - the Automatic Camera Identifier and Downloader

ACID is a Java application designed to simplify the process of getting a SDM or CHDK build for your Canon camera, written & published by zeno in May 2010.

  • ACID requires version 1.4 or later of the Java Runtime
  • Tested with MS Windows and Mac OSX


  1. take a picture with the camera
  2. put the camera card into a card reader
  3. run ACID and drag the photo from the card and drop it onto the ACID window.

Acid will then
  • analyse the photo
  • extract the camera model and firmware version information
  • automatically download the appropriate build of SDM or CHDK (depending on which button you press) to a folder you choose
