Okay, I can report the following:

- I will go snowboarding from 07.02.2009 to 15.02.2009
- Camera boots with latest DISKBOOT.BIN
- LED next to ISO blinks 3 times, then I can see the CHDK logo
- There are CHDK icons etc on the display (seems rather clutterd) [I'll attach a image soon]
  *Hitting the "Display Button" removes the default Canon Icons and it looks like plain CHDK
- When I hit the "Function Set Button" for a few seconds I can see a fancy Clock :-)
- Hitting the "Direct Print Button" brings me into the CHDK "ALT" mode
  * Pushing the "Menu Button" while in the "ALT" Mode i reach the CHDK menu
- Shooting RAW on a 32MB SD-Card does not make much sense :-)

I just came across the recent development with the SD790 and am so thankful. I only had a short amount of time to test out as much as I could. The only main difficulty I immediately noticed was that the scroll wheel doesn't respond or do anything. It normal is used to select Auto, M mode, Digital Macro or various other modes. But in both the ALT and Regular Canon mode, it doesn't do anything as far as I can tell. I'm not sure whether you knew that or not, but I hope it helps.

Oh and one question. Are the SD series cameras capable of Aperture Override and Av bracketing with CHDK? Compared to what the wiki states as being included in the CHDK build, it should include both of those. But neither of them appeared in the Extra Operations section. Is this just using an older build? Or does it have to do with the actual camera?

Anyways, thanks once again for all of your hard work. It is greatly appreciated. If you need any more info or testing, I'll do my best to help.

Most (all ?) of the IXUS/SD series don't have a real adjustable aperture, so CHDK can't add aperture override. The aperture is entirely dependent on zoom. CHDK can allow control of the ND filter.
Don't forget what the H stands for.

Amazing that this worked ..

I think the ixus90/sd790 has no iris and therefore no controllable aperture, like most camera's in the ixus series...

Can someone confirm that DNG support and bad pixel detection works ?

I'll see if I can guess the wheel control from other camera's with a wheel (anyone know which already-ported ixus has a wheel?)

I tried looking at the raw images, but i cant get anything out.  I have the actual files, but i think there may something amiss in the header info.  Even photoshop doesn't open them.

I've tried .cr2 .crw so far.

yeah the CRW files aren't REALLY CRW files. They just have that extension for convenience when getting files via the cam as opposed to via a card reader. You will never be able to read them with any CRW or CR2-reading software.

They're just plain dumps of the RAW data, with NO header info (you'll notice the size is 3720x2772x12/8 - the exact resolution without any header). Unfortunately 12-bit data is not something photoshop can handle, nor can it read bayer-pattern raw files (RGGB).

Easiest way is to run badpixel.lua (download it and put it on your SD card, then run from the script menu), then enable DNG support in the RAW menu. You can then view the DNG via eg Irfanview (downloadable program) or any other DNG compatible software.

Alternatively, I have attached a small win32 commandline program to convert to a RAW format that photoshop CAN handle: 1860x1386, 16bpp, Mac, 3 channels. This discards some data though, so using DNG is much better. DNG also has bad-pixel-fixing. I have attached the source if you want it too.

DNG works fine here.

Seems as if the IXUS90 is finally more or less ported.

Kind regards

There are 3 open issues:

- Movie capture code
- My ixus85 sometimes crashes when doing RAW capture, presumably since I use the same code, the ixus90 will have the same problem
- Wheel is broken
