Is there anyway to permanately apply this hack? I will be traveling this summer all over asia and to italy, and I don't want to turn off my camera and then spot something new, turn it back on and have to do it all over again

You can make it autoloaded - http://scratchpad.wikia.com/wiki/CHDK/FAQ#Q._How_can_I_make_the_HDK_firmware_load_automatically_at_startup.3F

So does it mean that we need to make sure we can change the hacked system back to the original one or the warranty will be voided?

I'd say: Make sure that you only download the CHDK versions from GrAnd's or Vitalyb's pages and you will be fine. They are designed not to touch the original firmware. They will be loaded in the memory only temporarily.

Don't use other .FIR files you find on the internet if you don't know exactly that they are only temporary. Perhaps they are "real" firmware updates which will permanently change the firmware or screw up the cam, and this will indeed void the warranty, I think. Exceptions may be official firmware updates which you find on the Canon homepage.

I honestly do not mean to put a damper on this discussion. I can care less if people install it or not. It certainly has worthwhile features. But in further disucssion with Canon about this specific hack, their response is:

"If it is not Canon firmware the warranty would be void."

Personally playing it safe, if I were to install the hack, it would not be until the camera warranty ends.

Well that sure is a relief, and that you got the official word on it. Because CHDK is not firmware. Firmware by very diffinition, even the reason it is called FIRMware, is because it has to stay FIRM inside of the camera even when powered off, retained in eeprom chips. CHDK does none of that. So it doesn't even qualify for Canon's concept of firmware and doesn't void any warranty whatsoever.

Thanks so much for the clarification and info. Now readers of this post, especially newbies, have enough info to make up their own mind.

Again, thanks.

I think it's a question that needs
to be asked by anyone adding hack firmware to their camera. If a
camera is on warranty, I'd want to be very certain adding a hack
won't void it.

It's probably worth noting that since the hack does not change the firmware, regardless of whether or not it might technically void the warranty, there would be no way of Canon finding out! I would be very surprised if it did void the warranty, though, since it's not actually changing anything within the camera - all the software does is read the information already available ...

I've happily put the CHDK on my A640, and I would not hesitate to claim the warranty if something went wrong with it ...

How would Canon know you'd applied this program - unless you told them? It is software (ie temporary program) not firmware (ie 'permanent' program). Makes you wonder why Canon does not provide such facilities within the camera - clearly people want these functions. Canon's marketing dept needs a rethink. I think too that their existence makes the cameras more attractive to some. RAW is very useful.

Unless the installation process is full proof, it would be just my luck to install it improperly and mess up my camera. But maybe it can't mess up.

The terms "nervous nelly" and "worry wart" come to mind.

I bet you're the kind of person that doesn't cross the street when the walk-light turns white or green until everyone else has already gone. Then you get hit by the car because because the light changed again just after you left the curb, still wondering in the hospital if you should have crossed or not.

A case of OCD perhaps?

In reply to JackSprat, May 12, 2007

Just researching the subject and playing devil's advocate until all the questions are answered. Hopefully the answers may help those less informed.

Do watch when you cross the street.

Guess it depends if you really need the features or not.
In reply to gail, May 12, 2007

If you really want the features, then go for it. If it's a matter of "I guess it'll be nice to have", and you worry about the warrenty, then don't do it. Personally, I am more incline to hack into it. But I have more background than most so I'm not that fearful.

To each it's own.

Transform them in DNG format. See the CHDK usage and FAQ.
