Hello

We have 8 PowerShot A2600 here and want to have a script which can be executed from a Computer/Laptop and does the following 2 things:

1.) Take a picture with all cameras at the same time
2.) Download the pictures back to the computer

An image will be taken every about 2 minutes so the speed after the picture has been taken doesn't really matter...
What matters more is that all the cameras are released at the same time.

Is there a script like this? If not, how can I get this to run?

You probably want to start here : CHDK Links : Multiple Camera Rigs. Pay particular attention to anything about chdktptp and the various forum thread links down at the bottom.

reyalp is the chdkptp author and expert. I suspect his answer might be that it's possible to do if you can write a Lua script that runs on the PC side and scrubs the camera directory file names looking for the highest numbers in the IMG_nnnn.JPG files. Not simple unfortunately but technically possible.

If you are using multicam.lua, use the mc:download_images function with lastimg=5

Note this will fail if the image counter has reset within the last 5 images.

The imdl CLI command also supports this, with -last=5

!mc:download_images({lastimg=5})

You can use mc:list_all() to see all the cameras multicam thinks it's connected to.

If you just want to know the number you could use something like !print(#mc.cams)

Neither of these check the actual connection status, so if a camera crashed it would still be included.
