I find it so embarassing when I screenshot something and my laptop suddenly makes a loud camera noise, gives the impression I’m taking photos of the people around me!
Seems there isn’t an easy setting for this – gnome being gnome – but I did find this solution. As hacky as it is, it works!
sudo mv /usr/share/sounds/freedesktop/stereo/camera-shutter.oga \
/usr/share/sounds/freedesktop/stereo/silly-camera-shutter.oga
