Here it is:

...now, I'm having some trouble when shot a photo: info on display shows, for example, 60/2.8 but the camera shutter stays open for much longer time and taken photos are all over exposed.
This issue occours also in fresh installed firmware.


So is that only happening with RAW enabled ? Do you have the problem with normal JPG shooting when CHDK is loaded ?

I just made a new test with raw disabled and the same problem happens.

Got the same complaint on the A495 port.  My SD940 does this as well so it seems to be a generic CHDK problem rather than port specific.


I found a way around this for the G12 and SX30 - see the special case code for these cameras in lens_set_zoom_point (platform/generic/wrappers.c).
You'll need to find the equivalent property values and function address for PT_MoveDigitalZoomToWide.

Thanks waterwingz, changing min./max. value has indeed some effect on battery status information.

I can confirm that video recording works well. (Although I've not tested each and every quality level due to my poor sd card.)
Also same issues here with zoom in/zoom out behavior. Switching back to optical zoom failed.

As stated in my last post, images are constantly overexposed (regardless of the activation of raw capturing).
I think this could be related to the ineffective settings in Extra Photo Operations. Maybe somehow settings are predetermined or fixed in the first place. This could lead to a constant overexposure or wrong measures which then lead to overexposure.

I tried to took at stubs_min.S and lib.c but to be honest it's all greek to me ;-)
So i think it's up to you to push things forward here ;-)

@simon96 :  Great feedback.  You are probably correct about the exposure problem being related to the Extra Photo Operations.  Is all likelyhood,  something in stub_min.S is pointed at the wrong place.   I'll wade through that but it won't be for a couple of days.

Hey there's no hurry. We're not in a rush. Take your time.
Waited for so long now, that "days" make no difference.
It won't raise boredom here. ;-)

It's great that you wanna stick to it, anyway.

Spent a happy couple of hours fixing up stubs_min.S and lib.c for firmware 1.01c.

Time for a little more testing please :  IXUS200_SD980 firmware 101c Beta5

Card lock boot method only as usual.

Let me know what you find - even if its just "boots" or "everything works".   Frustrating not being able to test this myself to make sure it still at least boots.

Ciao !

Still some problems with the exposure.

When i set the iso to 80, the image is reasonable decent, but looking @ EXIF the exposure time is way too high.

When CHDK is loaded, exposure is going 1/15 or 1/20, and when i take a picture without CHDK it lowers to 0.5/0.6.
Setting disable overrides in the extra photo menu doesnt help, also making pictures with EV +/ 2 in continiousmode, crashes the camera at the 2nd picture taken continiously.

Will post more when i find it. Thx again for the new beta

Edit1: shows battery time at 0%, and raw are also over exposed.
Edit2: seems the problem is more related to the ISO values always going to 800 when they are set to auto that cause the exposure time to be raised., when manually setting ISO to 80 it lowers the exposure time and pictures are decent enough.

Always a good idea to delete the CCHDK.CFG file when before loading a new version.  Delete it from your card and see if that helps ?

from one of my previous posts here :

I will give you one "free fix".  The default range for the battery icon in the OSD is most likely set too high.  You can change this in the OSD setup parameters - try setting the min to 0 and the max to 5V and see if you get a reading somewhere between that.  With most cameras, you need to test a fully charged battery and then with a battery that has just reached the point of shutting down the camera to determine the correct range. Post the results here and I will change the defaults.
