Nikon D3300 delay before taking a shot

Hello,

I am a new user, and i have been trying to control my Nikon DSLR with
gphoto. Specifically, i use the python3 bindings [0] for libgphoto2.

My problem is that between the time that the capture function is called,
and the actual time that the camera shoots, there is a slight delay.

Is this expected behaviour? Can fix this? I include the script i am using.

Cheers,
Kostis
