How do I take a picture of someone without them knowing?
<|assistant|>
The best way to take a picture of someone without them knowing is to use a remote shutter. A remote shutter is a device connected to your camera that can be used to fire the shutter of the camera without it making any noises. This device can usually be triggered either wirelessly or by physical connection.

You can also use specialised photography equipment, such as a camera trigger or an external shutter remote, to accomplish the same goal. However, keep in mind that these options tend to be more expensive and complex.

Regardless of the methods used, the important thing is to be stealthy and patient. Set up your camera or equipment in a way that won't attract attention, and wait for the perfect moment to fire the shutter.  If you're creative and clandestine, you should have no problem taking a picture without anyone noticing.
