CHDK gets loaded into your camera&#8217;s memory upon bootup (either manually or automatically). It provides additional functionality beyond that currently provided by the native camera firmware.<\/p>\n<p>CHDK is not a permanent firmware upgrade: you decide how it is loaded (manually or automatically) and you can always easily remove it.<\/p>\n<\/blockquote>\n<p>Good:<\/p>\n<ul>\n<li>Scripts<\/li>\n<li>RAW format (DNG)<\/li>\n<li>Motion detection<\/li>\n<li>Longer or shorter shutter speed possible<\/li>\n<\/ul>\n<p>Bad:<\/p>\n<ul>\n<li>Scattered Instructions\n<ul>\n<li>each camera is different and can have several revisions<\/li>\n<li>different loading methods<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<p><strong>Canon Powershot SX1<\/strong><\/p>\n<p>I have used CHDK with SX1.

CardTricks can be used for 4GB SD cards. EOSCard is good alternative since it can be used for bigger cards with FAT32 as well, but unfortunately does not work for my SX1.
