Please don't double post. I removed the other one...

* fudgey removes the moderator hat and replaces it with a developer one.

When I set up Bracketing in Continuous Mode with a TV Bracketing Value of 1 EV and a Bracketing Type of +/- then take pictures in continuous mode, it goes all screwy with the EV levels, resulting in the first picture usually taken fine but all the rest after are almost all white.

Does ND filter override (to either state) help?

Also using 1.00C version with an Ixus970IS and having the same problem with Tv bracketing. I was new to CHDK, so I thought I had a setting misconfigured, but seeing as I'm not the only one...

ND filter overrides (Off, Out, In) have no effect. Pattern is more or less as in frankgg's post. The first image is fine, but the "+" steps always seem to be way too high. The "-" steps might be okay. This is the case even when Tv bracketing is not set to +/- (AFAIR).

Probably the same with all the other bracketing. I tried it with CHDK a few months ago (same problems), but not with the version I downloaded tonight.

And thanks so much to everyone (like snc) working to bring the full capability of CHDK to the Ixus970.

Does ND filter override work (without bracketing)?

Sorry for the delayed reply. I'm not yet used to visiting this forum when browsing.

ND filter override works without bracketing (in/out).

Tv override works without bracketing.

Reported in  http://chdk.setepontos.com/index.php?topic=10822.msg121686#msg121686 it appears there may be a case where shooting can happen without hitting wait_until_remote_button_is_released

This means that USB synced remote and the hook_shutter shooting hook will not work.

Looking at the capt_seq.c, I see the raw hook is in two locations. One of those code paths calls a _my function that is contains the USB remote hook immediately before. The other calls the firmware version of the same function, rather than the hooked _my function.

I've attached a CHDK 1.4 test build for firmware 100b that calls the hooked function. I think this should fix the issue.


Don't forget what the H stands for.

Hallo reyalp,

a short reply, your attachment works.
The LUA script is running.
I didn't test it in deep, but I will do that later in the evening.

Thank you very much for your help.
I think it is great work to find an error like this without the camera.
IXUS 970 IS 100b

Thanks for confirming. I've checked in the change for all ixus970 firmwares, in both 1.4 and 1.3. It will be in autobuilds 4149 and later.
