Ghoto2 is a very capable piece of software but unfortunately the documentation is not very complete, even missing some import documentation. Last weekend I changed the photobooth software by letting the camera (and not the macbook) create the jpgs.
This results in a faster workflow bring down down the click-to-server time down to <2s which is as good as with Sofortbild.. Unfortunately, I couldn’t download the jpgs from the camera. After searching the net, I found an undocumented option
gphoto2 --set-config capturetarget=1
that lets gphoto2 write to SD and not SDRAM. Now
gphoto2 --capture-image-and-download --keep-raw --filename /Users/adminp/Original/picture/%Y%m%d-%H%M%S-%f.jpg
works as expected.
