Tethered shooting with a DSLR (shooting directly to a connected computer via a USB cable) on Linux is very, very easy, assuming you have gphoto installed.
And start shooting away! However, I wanted to be a bit cleverer and improve my workflow slighty to overcome a few shortcomings. I wanted to:
- Shoot raw
- Display the last shot full-screen.
- Not clobber existing files if I re-ran the tether.
