Later today I will make a version that only disables IS error if at least 30 seconds have passed AND you are in Record mode.

great, thanks :)

Right, I will deal with your time-lapse problem later today or tomorrow.

Thats ok, its a shame I havent been able to figure out how to do such a ...seemingly simple thing.

Heres what I'm trying to do:

What I want to do is, put the camera on my window ledge, turn the lights off in my room, late at night, and I want to take HDR sequence photos starting from shutter speed 1" and ending at shutter speed 65". I want the closest possible difference between them, i.e EV 1/3 minimum.

Thats all really. Ive done this sorta thing before but I had my finger on the button all the time, I want to leave it alone with no custom timer light flashing.

That is 20 (or is it 21 ?) exposures at 1/3EV interval and the camera in continuous shooting mode !

You realise that from just over one second, the camera also captures a black frame of equal duration ?

Total time for one sequence is double the sum of whatever the twenty times are.

The sum of 1,2,4,8,16,32 and 64 is 127.
Let us say with 1/3EV bracketing the sum is roughly 380.
Double that is 760 .. over 12 minutes.

Before we go any further, is this really what you are trying to do ?

@microfunguy,

Here is what I am trying to do:

I'm trying to take photos, lighter each time, starting from shutter speed 1 and ending at shutter speed 65. I intend to do this in the midnight, to capture the scene outside my window. My ultimate aim is to make an HDR with these captures.

Here is how I accomplish this currently, manually:

1. I go into SDM Menu by pressing DISP+MENU
2. I enter 'Bracket / Override' menu
3. I set Bracketing ty to [lighter]
4. I set Tv bracket val to [1/3 EV]
5. I take an elastic band with knot at one point of the loop
6. I put the band, making sure the knot is on top of the shoot button
7. I set the camera to continuous mode
8. I let it sit by the window till its completed.

What I would want:

I would want to accomplish what I have in the 'manual method' above, automatically. I'd like to do the same thing as above, minus the elastic band. Thats all.

Set bracketing type to 19.
Set shutter speed to 8 seconds.

Use this script :-

@title sh1981
start_continuous_sequence
wait_until_done
end_continuous_sequence
end

Ok, will try soon.

A quick question,

I took a photo at shutter speed 1/1500
I took another one at shutter speed 1/40000

Surely there should be a hell of a big difference right? Surprisingly there was little to no difference.

Does SDM really hike the speed up to 1/40000 or is it not applicable to ixus 105?

Of course not, neither does CHDK, it is nonsense.

I only leave those settings in the menu because some people would complain if I did not.
