How do I take a picture of someone without them knowing?

To take a picture of someone without them knowing, you can use a remote trigger, a self-timer, or a double exposure trick. You can also use the camera's silent mode or stealth mode to take a picture without making any sound. To take a picture using a remote trigger, set the camera up in a position where the subject would not be aware of it, then attach the remote trigger to the camera and press the shutter button. With a self-timer, the camera is set up in the same position and the subject presses the shutter after a pre-determined delay. For the double exposure trick, you take a regular picture and then carefully composite another picture into it by merging the two images in Photoshop. Finally, camera's silent mode and stealth mode allow you to take a picture without activating the shutter sound and thereby avoiding making the subject aware of it.
