HDRlapse.lua - an HDR intervalometer with fast shooting

I've linked a script that combines the fast shooting techniques discussed here : HDR_Fast_Shooter with intervalometer code and a few other goodies. 

Download link : HDRlapse.lua

This is a great idea. Keen on trying this script. But I was wondering why you didn't built it in the Ultimate Intervalometer? After all, it's called "Ultimate"

It seems that there is always just one more feature needed.  I'll add it to "the list".

Perhaps I should have called it penultimate.lua ? Except that does not fit nicely into the 8.3 file naming limitation imposed by Microsoft's patent trolling.

Well, then certainly the name "ConstantlyBecomingMoreUltimate.lua" wouldn't fit either... 

Hi, currently I'm using a regular intervalometer with the self-timer set to N photos and 0 delay and CHDK bracketing in continuous mode.

Would  this be faster?

Oh, might as well measure it....

Tested it on SX40HS.. got weird results.

In Manual mode set at 1/60, it took the first photo at 1/2000 and the rest at 1/3200.

In Aperture priority it started went 1", 0.3", 1/4, 1/30, 1/50, 1/320, 1/200, and 1/3200 till the end.

Setting for the script were default:
Number of Steps: 3,
1/2 f-stops per step: 2,
Shot Mode: burst.
Interval (Seconds): 2 s.


Changing the Shoot mode to fast made it more a bit more reliable:
1", 0.5", 1/4
1/15, 1/30, 1/60 till the end
But it slow, around 0.5 FPS


Using bracketing with self-timer, yields ~500-650ms between frames.

I guess it's not compatible with SX40HS.

The script wants the camera to be in P or Auto mode as it uses the camera's initial exposure reading & settings for the first shot then brackets from there.

Camera model should not affect it.  Initial shooting mode will.   I guess I can get the script to check that and show a warning message if necessary.

Edit :  this script (and those like it) will never be as fast as the camera's built-in bracketing modes - if your camera has such modes.   I believe the SX40 & SX50 do.

Ah, yes, tried it now and it's working.

Well, your script is faster then self-timer. I measured ~300ms between the shots.
Though I usually want everything on manual, so I'll have to take a proper look at the script, see if I could modify it for my purposes. At most I'd use Av aperture priority, everything else on manual.

Is there a specific reason why you chose only P/A modes for this script?

That's very good - much faster that most older or cheaper cameras can achieve.

As stated in my previous post,  the script "meters" the scene using the build in camera half-press mode and then brackets accordingly.  Just like 99% of people never use anything other than P or AUTO mode on their P&S cameras or consumer DSLR's, the script works that way too.

Ok so I go to use the script and I get an error code . My camera is a sx50hs
