TwoCamControl

Very quick (thanks to the chdkptp rsint command).
Trigger cameras with a GUI button, keyboard shortcut or mouse wheel.
Autonames files in sequence 0001L.jpg 0001R.jpg 0002L.jpg ...

Controls - Basic Workflow
Connect cameras.
Adjust Zoom and Focus. Preview shots with current settings.
When the settings are good start a New Project and Shoot.

Nice work! :)

If your camera does not support filewrite support, it is possible to ask for the support posting to CHDK international forum. This thread in particular discuss the implementation of fwt for several cameras. Or post the request to the corresponding model porting thread.

This is great! Now I have some thing to recommend for people without a Raspberry Pi. :)

dtic, I am continually astounded by the great things you are able to do with AutoHotKey.

Really cool! I'm going to have to try this out myself. Many times, for prototyping, I've wished I had a utility just like this.

Thanks for your work, dtic!

Thanks people! Do try it and post any bugs here. It controls chdkptp by sending input to two cmd windows and timing for that can vary depending on how fast the CPU is so posts confirming that all works well are of use. I'm especially keen to hear if all commands work also on older/slower PCs.

I should have put this in the OP: TwoCamControl has no preview mode, since I've had no need for that myself. But as photos are downloaded immediately anyone who wants that could make a small script that monitors the project download folder and displays the two most recent images. I might do that later.

(solved! i've installed the autohotkey program you mentioned) hy dtic, nice work with this. i'm trying to run this script, i've set it after the recommandation but when i'm trying to run it, error at 340 line pop up. i've installed chdkptp 5.47 and followed the steps in the .txt.

I sent PM to mihai2054 and he has already solved the issue (related to an older autohotkey version installed if I understood correctly). He uses Win 8.1 so now we know that TwoCamControl works in 8.1 too.

I feel bad about asking this, but I am following the link to download the chdkptp, but when I get there I don't find a link to download. I do see link to chdk and ptp extension, but neither seem to be appropriate.

Thanks for your guidance:)

Hi, on the linked chdkptp page ( https://www.assembla.com/spaces/chdkptp/wiki ) there is a top bar, click "Files" there. The layout is a bit confusing. Here is a direct link https://www.assembla.com/spaces/chdkptp/documents

- chdkptp downloaded and unzipped ( https://www.assembla.com/spaces/chdkptp/wiki )
Note: For now use chdkptp version r547. Versions r592 to r650 has a bug that breaks TwoCamControl.
Hi, was that bug fixed? what is the problem? Thanks
