Canon cameras firmware hack

According to the CHDK wiki, that camera is not supported yet.

Looks like support for this camera is progressing (ixus SD990 / 980IS), a very early version of CHDK was up and running over the weekend.

You can follow the developments on the porting thread: http://chdk.setepontos.com/index.php?topic=2972.30

I'm watching this with interest as I'm looking for a new compact that will take the inon UFL165 fish eye and save RAW. Options for this seem to be either very old cameras (e.g. canon powershot S30/40/45/50 or early G series models), or more recent canon models with CHDK.

Can anyone comment on the ease with which the RAW output from CHDK can be used? Can you combine the EXIF data from the jpg with the RAW file as an input to photoshop?

Does anyone know if the raw output ( .CRW files on my card) can be used in Gimp. So far, when trying to open the .CRW image, I get a message that it is an unknown type.

Maybe I can answer my own question. ufraw is a plugin for Gimp that does that.

I'm not sure if this model's hack can write directly to DNG, but if not, download and convert using this free software linked here:

I used it before the CHDK hack was developed to write to DNG directly for my A570IS. You should then be able to open the DNG files if Gimp supports DNG.

Something to note, though, is that on some cameras, the "enhanced menu" button is assigned to the "print" button on the camera, and Canon does not implement this on their underwater housing, strangely enough . There are some workarounds, if anyone is interested they can ask me.

Aasmund,

I'm quite interested in the work around for using a button other than the direct print for access to the menu. I have a SD1000 that I use with CHDK, and want access to the setting while I have it in my Canon WP-DC13 case.

I'm new here so I can't message you, but you'll probably be able to message me.

Thanks

Hi all!

 

The CHDK firmware hack is truly a brilliant tool, and it works well. B)

Sorry for bringing up an old thread- but i would be VERY interested in hearing about this. Its one of the only limitations i can find using this hack with the camera in the housing. I would like to over-ride Tv, iso and Av settings through the cdhk while underwater, but cant currently. i have to set them at surface and leave them. Some shot combos just cant quite work with the settings- say setting Tv to 2000 to get really black backgrounds on macro strobe shots, then switching to wide-angle ambient shots with the fisheye- i'd be stuck at Tv 2000.

Cheers!!
