Hello All,
One-press bracketing for the Ixus 95 SD1200 does not work (it does in SDM) and I cannot get zoom during video to function. It is enabled and there is a stub for it. The stub is the same in CHDKDE and SDM, does anyone have it working?
I also find that Remote does not work well in CHDK, but does in SDM 1.85, on the Ixus 95

Best,

Colin

@Microfunguy- Ixus 95 SD1200.
You must know the reasons why bracketing and remote work on SDM? If you let me know which parts of your code to use, I can copy your code for these features into CHDK?

Best,
Colin

I heard that this camera has 12 bit raw. Does it positively affect DNG quality much(given higher pixel density), compared to older cameras' 10bit raw?

I do not know about that, but here is a shot from my Ixus 95, originally in RAW http://www.flickr.com/photos/31637627@N08/4603083887/#in/photostream

I think you've give a wrong link...flickr says: This photo was taken on May 13, 2010 using a Canon PowerShot G9.
Please provide original raw file from SD1200, if possible

Whoops,
I cannot do the original RAW, but this one is a three shot HDR done in RAW, from my Ixus 95 http://www.flickr.com/photos/31637627@N08/5513471214/#in/photostream

Best,

No offence, Colin, but your HDR is not something that illustrate 12 bit advantage.

So it means 12 bit ADC makes no sense in terms of SD1200 raw quality. Thanks.

Apologies if this has been addressed somewhere upthread and I missed it:

I just installed CHDK on this model per the "make bootable" instructions (noob on CHDK, not noob on SW/firmware in general).

Operation of the ON/OFF button is as-expected with the SD card unlocked: lens extends, camera is ready to take pictures, all good. When the card is LOCKed and I turn the camera on with the ON/OFF button (NOT the Playback button), I get the CHDK splash overlay but the camera comes up in Playback mode.

I don't know how to switch to picture-taking mode, or if this is a known bug. Is this atypical for this port at this point in time? Is there a workaround?
