Nice, if you want i'm here for testing the "one shot usb" function with my two Ixus.

Here you go. Beta release of version 2.5 of the kap_uav.lua script is here > kap_uav_2.5_beta.zip

There are new options for the USB Shot Control parameter :

Off : USB power ignored
Interval : intervalometer runs normally when USB power is applied, off when no power
Single : script takes one shot every time the USB power is applied
PWM : script detects width of power pulse and calls a subroutine to a match

Notes :

as written the script assumes Gentles CHDK2 USB cable PWM timing. Edit script for different devices.
for Single and PWM modes, pulses are buffered ( up to 8 ) so if the camera is busy the next pulse is not missed.
PWM mode currently only prints a message (& shoots for shorted pulse). Edit script for different actions.

Update : this has been tested with a pulse width modulated signal from an Arudino microcontroller is I'm pretty sure it works correctly.

Hi Waterwinz,

Thank you sooo much for this script.

I have an IXUS 132 and do not appear to be able to lock the camera into infinite focus. I have tried AFL and @Shot & MF but it will continue to attempt to focus with the small blue square appearing on the screen. The log shows that it is not focused at infinity, but it does not give me any errors.

Attached Log File.

Thanks.

What version of CHDK are you using ? (the full filename of the CHDK zip file you installed) And what version of the script?

Did you disable the Canon ServoAF and ContinuousAF modes? Those modes will override the CHDK Subject Distance Override settings.

Looking at the log, Canon auto-focus is probably focusing your pictures probably correctly though CHDK is unable to lock the focus (see previous comment).

Meanwhile, I'll add a log of ServoAF and ContinuousAF states at the next script update, just for this reason.

Hi there

This is my first post related to KAP, and I really appreciate the script. I took a few pics with the stock intervalometer, but all were blurry.

I'd like to ask for camera and shot specific analysis help, as far as setting the mins and maxes and such, and I'm not sure if it's better to ask here or start a new thread in the general newb forum.

I got three decently clear shots out of about 50 this morning, some cloud cover.

For now, I'm just gonna throw up the first few lines of the log:

2014May23 10:51:00 CHDK 1.2.0-3439 a495 100f May 12 2014
2014May23 10:51:00 Tv:1/1000 max:1/2000 min:10 ecomp:0.0
2014May23 10:51:00 Av:4.0 minAv:2.8 maxAv:8.0
2014May23 10:51:00 ISOmin:100 ISO1:400 ISO2:800
2014May23 10:51:00 MF mode:0 Video:0 USB:false
2014May23 10:51:00 AvM:2 int:30 Shts:0 Dly:60 B/L:0
2014May23 10:51:00 entering start delay of 60 seconds

And a few more lines from the log:

Blurry shot:

2014May23 10:53:38 4) IMG_1535.JPG
2014May23   10:53:39   meter   Tv:1/800   Av:4.5
2014May23   10:53:39   actual:   Tv:1/1000   Av:-   Sv:320
2014May23   10:53:39   AvMin:3.2   NDF:NDin   foc:0.9m

I think the "foc:0.9m" is my problem there.

Clearer shot:

2014May23 10:54:38 6) IMG_1537.JPG   IMG
2014May23   10:54:39   meter   Tv:1/1000   Av:4.5
2014May23   10:54:39   actual:   Tv:1/1000   Av:-   Sv:200
2014May23   10:54:39   AvMin:3.2   NDF:NDin   foc:infinity

"foc:infinity" is the only parameter that I understand well enough to see that it's significantly different.

I intend to get out again this afternoon or tomorrow morning, and I'd like to know what I should try changing.

My preferred method of messing with this kind of thing is to save my own edits as revs, for specific conditions. I'm thinking I could set "foc:infinity" in the script, and possibly Tv min:1/1000.

Is there anything else I should be looking at, or should those two get me better pics?

Happy to post the pics, but I didnt see many others doing that.

Thanks for any help.

Here works fine for me - and I suspect I'll be answering most of your questions. However, I'm travelling for the next couple of days on a photography trip somewhat at "the ends of the earth" so network connectivity might make my response time a little slow.

You probably want to crank Tv max up. Way up.

That's one problem. With MF Mode set to zero, the script will not attempt to lock focus at infinity for you and is doing its best to autofocus instead.

Also, the ND filter is engaging - probably because its a bright day and you have set the maximum shutter speed quite slow.

You do all that with the setup parameters in the script menu. You can even save as many as 10 different combinations of parameters for later use. If you are not familiar with that, scroll down in the CHDK script menu - the kap_uav.lua script has a lot of things you can adjust to suit your application.

We can cross that bridge when we come to it.

Regarding the shutter speed, the a495 specs show max shutter speed 1/2000. Will it make any difference to set it higher?

Regarding the focal length and MF mode, what's the recommended setting?

Last, the three times I've been out, a set of two AA batteries has lasted about 30 minutes. Is this expected, because the script is using a lot of processing power? Or am I doing something wrong? I've used fairly new Eneloops, and brand new disposable Duracells.
