Yes that would be very clear.  Then if they still want to work with the chdk they can stay here and the thread is clean and if they want to move over to the sd780 sdm build they can move to a sdm specific thread.  

The biggest problem I face is that I'm a computer guy not a photographer.  So often I don't know what people are talking about when they speak photo terms.  :(  Worse than that I don't know chdk enough yet to know if thats a special feature or just a bug or a misunderstanding.  I also don't know SDM.  Basically I'm messed either way.

Well, the tester says that the 'aperture' did change when the ND filter was forced in.
I have asked for more details, but that will be tomorrow morning now.

The addresses of the ND filter in/out functions are the same as in CHDK.

Any news on 1.00b or is that just not going to happen?

@lexluthor - Sadly I have had no success in getting 1.00c to use the write function.  This mean that 1.00b still would require blinking.  I haven't given up all hope but I'm pulled in a lot of directions at present.

Sorry, still a noobie.


I tried to test the 1.00c build by loading it on my 1 GB Sandisk Ultra II SD card via Card Tricks.  Also made the card bootable, and put the card in the lock position as required in the past to make the card bootable.  Took the card down to my local Best Buy to test it out on the SD 780.  Camera mode would not turn on/power on.  Playback mode works and shows the CHDK splash screen, but there were no images to view.  Best Buy staff advised me that since the SD card is in the lock position, it will not allow the camera to be in picture/video mode,, and the lens does not come out.

Is this true or am I doing something wrong.

With CHDK, newer cameras always startup in playback mode, that's a side effect of the way CHDK works.

Just press or half-press the shutter button once to switch to record mode !

On some cameras holding the power button for ~1 second starts directly into record mode, i don't know whether this will work on the SD780...

I asked the tester :-

" and if you then take a photo (ND constant exposure mode Off), is the
photo incorrect exposure (it will be darker or lighter)."

He replied :-

"correct it is darker - exposure and shutter speed are equal to ND filter off"


The Canon firmware does not 'know' about the ND override so the displayed aperture value is the same.

Take a photo with CHDK and ND override, it should be too dark or too light.

Thank you.  I  understand how CHDK ND filter override works now.  SDM "ND contant exposure" gives me what I really wanted, except that it doesn't seem to work with 8gb cards.

Thank you very much!

Where can I find the override aperture option in 100c?
The IXUS 100 / SD780 do not have a real aperture, only a ND filter - as all other Ixus series cameras; so there's no Av CHDK override, only a ND filter override.
