You want to take a selfie but your arms are too short? A group photo is made but also the photographer shall be in the picture? These are two of many applications of a remotely operated camera.
Install this app on two devices: One will act as camera the other connect via Bluetooth and can remotely control it. On the remote control device the user interface is like on a camera application: the preview is displayed and settings like brightness, flash mode, zoom, focus area and picture size can be chosen. Zoom can be set by a two-finger pinch on the preview or setting a slider, the focus area is determined by a single tap. By pressing the shutter button a picture is taken. The confirmation is given by sound or/and vibration or/and message. A trigger delay up to 10 seconds is possible. The remote control device stores all camera devices which it has been connected to and the respective last settings of picture size and flash mode. From the device list one can be chosen for automatic connection.
