An increasingly common feature on digital cameras at all levels. The camera sets up a Wi-Fi hotspot which you can then connect to with a smartphone or tablet. The camera maker supplies an app which you can use for transferring photos to the device and for controlling the camera remotely.
A technique used by professional studio photographers where the camera is connected to a computer and the computer is then used for controlling the camera, checking pictures as soon as they’re taken and then correcting and enhancing them as necessary before saving.

Horribly popular gadget that mounts your camera or smartphone on the end of a what is essentially a lightweight monopod – some are rigid, some have extendable sections. The camera can be fired using the self-timer or, sometimes, by a built in remote release.
Popular feature on smartphones, compact cameras and many mirrorless models. On a smartphone you use the front-facing camera so that you can see yourself on the screen as you compose the shot. On regular cameras you use a flip-up/flip out screen and face it to the front.
