CHDK allows you to quickly and easily perform bracketing using an extra photo override. CHDK bracketed photos are perfect for making HDR (High Dynamic Range) images in your favorite photo editor. In this post I will guide you through the steps required to take bracketed photos using your Canon Powershot Camera and CHDK. You can also use the bracketing techniques mentioned in this post to make HDR panoramas and equirectangular images for use in 3D graphics packages with the addition of HUGIN or PTGUI.
