Bracketing script suggestions

Hi. I've been greatly enjoying the bracketing script. I have some suggestions to make it even better... hopefully  :)
Basically, I'd like to reduce the number of steps involved in shooting with the bracketing script.

1. Suppress the flash if flash = auto.
If left on the default (auto-flash) it seems to shoot part of the exposures with flash and part without flash, which seems undesirable.
Without this feature, I have to go out of alt-mode, disable flash and re-enter alt-mode before using bracketing.

2. Have a short delay after pressing the Set button to start the first capture.
I use a mini tripod, and pressing Set (forward motion instead of the usual Shutter button downward motion) seems to introduce a small shift that misaligns it with the rest of the images.
Without this feature, I have to go out of alt-mode, set a 2 second shutter delay, and re-enter alt mode before using bracketing.

3. Suppress the Preview time for each exposure.
I couldn't figure out why each individual capture took so long until I realized it waits for the duration of the photo preview before shooting the next shot. I normally like this feature, but when shooting bracketed shots it becomes a liability: the longer the whole series takes, the bigger the chance things change between each shot (people walking into the scene etc).
Without this feature, I have to go out of alt-mode, go into menu, turn Review off, leave the menu and re-enter alt mode before using bracketing, then reset my Review time afterwards.

Of course, these suggestions may not make sense to everyone, so comments are welcome. (I have next to no coding skills, so all I can do is make suggestions  :)

Cheers,
Damon

If these suggestions are for a particular script, you should probably tell us which one. This would belong in the script forum, not here. It's also a good idea to tell us what camera and CHDK version you are using.

Don't forget what the H stands for.

Wow, not a single response...
So much for community suggestion I guess.

Hm.. first of all, allbest #47 is stone age old. I dont know if it already includes the scriptless bracketing feature. Most of the problems you experience are related to the nature of scripts running in alt mode.

In the recent build, there's a scriptless bracketing function - you just take the cameras custom timer / continous shooting mode, and instead of shooting a series of images with the same exposure, chdk changes the exposure between each shot.

Get a new build, try out the builtin bracketing function, and then see again if you still have the problems described.

Ok, I see what you mean. So I can only take pictures in the regular mode. But how will I be able to use features such as bracketing?

Enter the <Alt> with PRINT, enter CHDK menu with MENU, set up wat you want...


-> set "TV bracketing value" to [2 Ev], "Brackting type" to [+/-], exit Alt mode, use the custom timer (set up to 1s delay, 3 shots)
