What is HP Theatre Mode
Theatre mode is a special photography mode in your HP Photosmart R817 or R818 digital camera that is designed to easily let you take effective photographs in a “Theatre” like setting such as a theater, museum, sporting event, church. Typically, when people take photos at an event like a school play – the camera flash fires and the image captured is of the backs of the heads audience members. The stage is usually a dark distant scene. If you remember to turn off your flash – then usually the camera will switch to a long shutter time and the photograph will be blurry either because you moved the camera or whatever you were photographing moved.
In HP Theatre mode the camera is programmed in a way that will enhance the ability of the camera to capture that distant stage scene without motion blur and without photographing everybody around you. Because a Theatre is a very challenging environment for a camera, not every photo will turn out so be sure to take several. Since the camera sound, focus assist light and flash is off – you won’t bother fellow audience members.
How does HP Theatre Mode work?
In Theatre mode, the camera is set to operate in several special ways.
•Flash, auto focus assist light and sounds are turned off.
•Shutter speed is allowed to automatically vary, but is prevented from dropping too far to prevent motion blur and the aperture is opened for maximum light gathering.
•The ISO rating of the camera is increased beyond what is normally available, increasing the camera sensitivity to light.
•Camera exposure metering is optimized for the rather special lighting circumstances in a Theatre – such as a bright stage in a dark room.
•HP Adaptive Tone Mapping is utilized to further enhance and balance the contrast of this special scene.
•HP Adaptive Noise Filtering and Sharpening are optimized for the low light situation.
Some of these setting could be set using manual, shutter or aperture modes – but not all of them – and it would take a number of special settings. HP Theatre mode does it all automatically.
