pixeldoc, do your ISO override work with flash enabled or crashed the cam like in sx210?
Flash override does work under any condition AFAIK.
Looks like ISO override does not work ATM.
Camera does shutdown with certian overrides, but looks like Flash override does not cause any problems.
Cound'nt find any reproduceable condition to force camera to shutdown.

Thanks Pixeldoc the sx210 flash override works too,

what crashes is any flash(no necesary override) with any ISO override,

the Iso override works ok with no flash.

maybe your ISO overrides dont work due to propsets, checkout the sx210 to see if they match.

[edited to correct some findings - wrong version]  :haha

ISO override is working for me with no flash - otherwise the same as asm1989 reports - I have brought it down to 60 ISO ok and pushed up too, with Av and Tv settings constant its changing the exposure broadly inline with what I expected though I haven't compared to an DSLR yet.

Forcing flash (any value) doesn't work - camera does not crash though.

Single shots and bracketing with Tv works ok with no flash (at the moment that doesn't bother me - as I am using a movie light).

Side note on camera crashes : given the camera has an iris the ND filter isn't needed as far as I can see - I tried it out though to see what creative effects I could get. With ND filter IN and aperature open the camera always crashes.

I have found long Tv expsoures when bracketing causes a crash. However it is not always reproduceable.

Sometimes with a bracketed sequence I seem to get a different exposure in the first shot when compared to a single (non-bracketed) shot with the same Av, Tv and ISO. It does not happen often and I am still trying to reproduce it everytime but so far no luck.

Bracketing only works for Tv - in Av mode for example with an Av override set and a Tv value it is produces brakceted shots as expected with changes to the Tv values. When set to bracket Av's I noted in play back it shows the changing F stop value but the image is the same. I have a manually set of brackets where just the Av is changed against a constant Tv - the CHDK brackets show no difference.

Minor point - the CHDK battery meter always shows 100% so have to use the Canon meter - camera has run out of power and the CHDK meter is still showing full.

Thanks for your work on this - I am happy with its current functionality with manual Av and Tv values set for single shots and Tv brackets is a bonus - gets me out of a problem with the underwater housing.

Will added these findings to GitHub.

I'm gonna have a look... Thanks.

Actually, "Force manual flash" settings does only work in manual mode. In auto mode the icon does change from flash disabled to enabled but flash does not fire. I also didn't test this with Bracketing yet.

Side note on camera crashes : given the camera has an iris the ND filter isn't needed as far as I can see - I tried it out though to see what creative effects I could get. With ND filter IN and aperature open the camera always crashes.
I'm still confused about ND-Filter. Canon Firmware does contain ND-Filter functions like other cameras. Maybe ND-Filter stuff should be disabled in chdk, dunno.

Minor point - the CHDK battery meter always shows 100% so have to use the Canon meter - camera has run out of power and the CHDK meter is still showing full.
FIXED - I noticed this already but always forgot to fix it... default Battery min/max voltage was wrong. Change MAX Voltage setting to around 4100 (mV) and MIN around 3200 (mV) at chdk osd settings. Enable "Show Battery volts" and observe your Battery voltage after charging your Battery to get MAX value and wait for Camera to report Battery empty for MIN value (don't forget to post is here).
main.c
Code: (c) [Select]
// Battery default min. Voltage
long get_vbatt_min() {
    return 3200;    // ToDo: use real value, this is just a guess
}

// Battery default max. Voltage
long get_vbatt_max() {
    return 4100;    // ToDo: use real value, this is just a guess
}

Thanks for your work on this - I am happy with its current functionality with manual Av and Tv values set for single shots and Tv brackets is a bonus - gets me out of a problem with the underwater housing.
Feedback is always welcome!
Strang to see so much chdk user use underwater housing. Maybe i should try to dive too ?!?

Is there anything I can do to help you fix the shoot command? E.g. provide you some debug info?

Sorry, i read your post about this, but still dunno what cause this issus.
You can always have a look at the chdk source code on github and understand how shoot command stuff does work;)
We have to determ how it's "suppose" to work and if this issus exist on other cameras...
I've only tested it with remote yet.

Hehe, unfortunately I'm a complete newbie to CHDK, and everything you guys do here is pure magic for me. ;-)

I've only tested it with remote yet.
That's exactly what I'm trying to do. But for remote shutter release I need a script like the one here http://chdk.wikia.com/wiki/USB_Remote_Cable, which uses the shoot command, right? Or what did you mean, you tested it with remote?

"make card bootable" only works on FAT16 partitions and 4Gb is the largest partition supported.  You need to split the card into 2 partitions - a small FAT16 one (16MB) to hold DISKBOOT.BIN and the other to hold photos, scripts etc. Try using CardTricks - or if you have a Mac, my SDMInst app (it will install CHDK as well as SDM).

SDMInst work but my cam save the pictures @ partition 1 not an partition 2 ;(
it is possible that the beta 5 is not compatible for 2 partitions ?
