The zoom doesn't work with the camera in <ALT> mode ... when I press <ALT> and go out of CHDK mode, then I can use zoom again (but not the remote). Anyone know how to get the zoom to funtion manualy ?

That's right, in alt mode the zoom dial has different functions.
But since you are using a script for the remote button anyway you can just add zoom function to the script using the set_zoom command.
Or you could just try to click the buttons, like this:

Code: [Select]

if is_key "zoom_in" then click "zoom_in" not sure about it though...

Here is how it is set up . Tomorrow I will attach it to the wheel chair with flexible arm and clamp.

The big view finder is really interesting. Might set up something like that myself.
As for your zoom script try something like this:

Code: [Select]

@title Remote trigger & zoom
:loop
  wait_click 500
  is_key k "remote"
    if k=1 then shoot
  is_key k "zoom_in"
    if k=1 then click "zoom_in"
  is_key k "zoom_out"
    if k=1 then click "zoom_out"
goto "loop"
end

You can also set other keys to zoom in and out, which might be more comfortable.

I don't know if there is a difference between the A570 and the A570 IS, but you might want to check the SDM version for the camera. It does not require you to run a script for the USB switch to work. It has many features that you won't need, but will perhaps solve your problem of using the zoom and the switch without too much fuss.

I think SDM is SteroData Maker:

StereoData Maker

It is based on CHDK--and optimized for connecting two cameras next to each other for stereo photography... It does use the USB switch (just like you did) to sync trigger the cameras (perhaps with out needing a basic script to run???). Not sure it would have any other advantages for you. (whoops, missed that cybercom posted the link to SDM...)...

And, as far as I know, there is only one model of A570/A570IS--it is the same camera--people occasionally drop the "IS" (Image Stabilization) because it is redundant when identifying the camera model.

Sorry to answer the wrong question about power consumption--but I think you have it nailed already.

Look'n good!

@Aristoc,

Click on the StereoData Maker link and it will take you to the site where you can download and install the SDM version for your camera. You will then no longer need to run a basic script to use the USB Remote to trigger the camera.

This will greatly simplify the operations for your friend.

Hi all,
We have been testing the camera and it took a few pictures no problem .Then it started to hang on focusing. It focuses then doesn't shoot the picture. Is there an adjustment I should do ? In the script iteself or the chdk menu settings.

Otherwise I have to turn off the camera and DVD player and restart.

Thanks again.
