Some Canon cameras can be hacked with a tool called the Canon Hack Development Kit (http://chdk.wikia.com), which does interesting things like add manual controls and allow scripting. Do similar tools exist for other brands of cameras? HP cameras, in particular?

  • Does CHDK work on Canon DSLRs or just P&S? I thought it was the latter. – Reid Jul 16 '10 at 13:42

    Seems to just be the point-and-shoots; however, on a DSLR, you already have good manual controls, so it's not as useful. – snostorm Jul 16 '10 at 14:02
  • An example would be: on my Nikon D90, button remapping is possible, but extremely limited. Hacking could increase this flexibility. – Reid Jul 16 '10 at 15:31

    Don't forget that a few (four, I think) Canon DSLRs also have Magic Lantern, which is in much the same spirit as CHDK. – nchpmn Apr 10 '11 at 22:31

The chdk project is the only one I've heard of.


There is an ongoing project to analyse and de-encrypt the firmware of Pentax DSLRs:- Pentax Hack
