This command takes a manual photo using the built in camera. The user must take the photo by pressing the button.
The filename$ is the name of the image file that the photo should be saved as. The extension determines the format of the image file and may be ".jpg", ".jpeg" or ".png". Jpeg is the preferred format since it takes much less time to save.
filename$ will always be overwritten by this command.
The shutter sound can not be disabled since it is illegal to do so or to give the option to do so in most places.
