Thanks for the info.
I'm not sure if I understand this correctly, if I go for a certain shutter speed with tv, wouldn't I want exactly that speed, not a corrected one? Would it help to have the ISO adjusted or is that no more free as a parameter then?

My remark above concerns something that could  have been done, but is not  actually realized in the CHDK code. A suggestion only.

Thanks, I was aware of that. I was thinking if in such a case the ISO could be adjusted instead of the already chosen Tv value, but maybe thats physically not possible? Thanks for any explanation.

That's what Canon do in the Sports scene mode - increasing ISO...you can do this also manually with CHDK, but the camera doesn't do it automatically.

Controlling the ND filter is useful e.g. in a script where you also set other values 'manually', whoever's way would be helpful with 'normal' shooting when you just want to select the highest 'Av' and let the camera select the adequate values for ISO, Tv & the flash (=Av priority).

Maybe the Extra Photo Operations: Custom Auto ISO feature could be helpful, i haven't used it sof far, i normally set up the lowest possible ISO...

Hi, I've a A1000IS 1.00b and I'am trying Diablo's port of CHDK from 2nd DEC.
CHDK works excellent, but I'm not able to process RAW...
Common utilites stops with error, but in IrfanView's RAW plugin I can recognize picture data from another image previously stored on the card... Very strange...

Hi -
Sorry for the newbie question, but is there some sort of beta version of chdk for the A1000IS?  I noticed several mentions of uploading the build somewhere, but can't seem to find it.

Thanks to all who are putting in the efforts!

for rev 1.00b

You have to be logged in to see the download.

bug report - custom iso
« Reply #88 on: 27 / December / 2008, 05:27:56 »
A 1000 IS  firmware 100b

Custom ISO values are a factor 1.6 off, e.g.
-> extra photo operations -> disable overrides (off) ->

Override ISO value: 10   (swapped, this is actually the multiplier)
Value factor: 10            (swapped, this is actually the custom ISO value)

should result in ISO = 10 . 10 = 100   
but resulting ISO value is 160  (10 . 16)

or

Override ISO value: 2   (swapped, this is actually the multiplier)
Value factor: 100         (swapped, this is actually the custom ISO value)

should result in ISO = 2 . 100 = 200   
but resulting ISO value is 320  (2 . 160)

Could anybody confirm? Thanks
Norbert

bug report - cchdk.cfg corruption
« Reply #89 on: 27 / December / 2008, 05:40:20 »
A 1000 IS  firmware 100b

I noticed that the cchdk.cfg file can easily get corrupted.
For example, a shutdown of the camera due to low battery voltage seems to corrupt the cchdk.cfg file.
The result is, that the cam will not boot into chdk until cchdk.cfg is deleted or restored from a backup.
Maybe an additional 'file close' / 'file open' at a strategic place in the software could help?
Alternatively, could a backup cchdk.cfg be restored if a failure in cchdk is detected?

Thanks
Norbert
