All Reset (or a similarly worded option) will be found within the menu of many cameras. Activating the All Reset control returns the camera to its factory default setting, cancelling most (if not all) personalised settings. It is very useful when the photographer purchases a new camera as it enables the user to explore thoroughly the camera's controls safely in the knowledge that should the experiment turn pear-shaped, there is an easy route of escape.

However, some cameras leave the factory with the All Reset turned on as a default setting. Turn it off, otherwise it can be annoying as any intentional changes the photographer wishes to make to the camera's settings (like turning the flash off) will be cancelled returning the camera to its default setting every time it is switched off.

Some older and inexpensive cameras do not always have this facility and will return to the factory default setting whenever they are turned off.
