quartz composer plug-in to trigger capture from a tethered camera. patch acts on the rising edge of the Capture Signal input and provides image output asynchronously, as indicated by the Done Signal.
Download - CameraObscura-0.3.3.zip
to install from the binary download, move CameraObscura.plugin to ~/Library/Graphics/Quartz Composer Plug-Ins/, and to install from source, simply build the Build & Copy project target.
when run, the patch will automatically select the first available camera detected that supports tethered shooting. multiple instances of the plug-in can be used simultaneously, each linked to a separate camera. the plug-in's selected camera is not yet serialized as part of the composition.
the debug builds dump lots of messages to the console, give it a quick look for camera connection and recognition status. not all cameras support ImageCaptureCore's tethered shooting. those supported by this patch are likely to be similar to that of aperture 2+ and Image Capture (refer to the buggy Take Picture action accessible from the File menu). see link below for a supported camera list and additional usage and debugging information. one may need to try PTP or PC Connection camera communication mode to find a successful pairing. http://support.apple.com/kb/HT1085
