If I could go back and relive the last few years of my life, I would relive each moment in exactly the same way. This simple realization emerged from deep internal reflection. Some people exercise or practice yoga, others meditate; I engage in walking meditation practice.
Most camera phones are simpler than separate digital cameras. Their usualfixed-focuslenses andsmaller sensorslimit their performance in poor lighting. Lacking a physical shutter, some have a longshutter lag.Photoflashis typically provided by an LED source which illuminates less intensely over a much longer exposure time than a bright and near-instantaneousflashstrobe.Optical zoomandtripod screwsare rare and none has ahot shoefor attaching an external flash. Some also lack aUSBconnection or a removablememory card. Most haveBluetoothandWiFi, and can makegeotagged photographs. Some of the more expensive camera phones have only a few of these technical disadvantages, but with biggerimage sensors(a few are up to 1″), their capabilities approach those of low-endpoint-and-shoot cameras. In thesmartphoneera, the steady sales increase of camera phones caused point-and-shoot camera sales to peak about 2010 and decline thereafter. Most model lines improve their cameras every year or two.
Mostsmartphonesonly have a menu choice to start a camera application program and an on-screen button to activate the shutter.Some also have a separate camera button, for quickness and convenience. A few camera phones are designed to resemble separate low-end digitalcompact camerasin appearance and to some degree in features and picture quality, and are branded as both mobile phones and cameras. information provided by Wikipedia.org
