Answer 1

I build a photobooth with a Raspberry Pi 3 and a Canon 600D DSLR. I use the same command and display the image after all. It takes about 7 seconds and is always an issue for costumers, because they want it to be very fast. The only solution i know is to use a camera attached directly to the graphic unit of the Raspberry and not via USB, wich does not work with a DSLR. That is the fastest way. But therefore you have lower image quality.
