accept modified programming from an image chip, and the software to trigger a slave camera from a master has been developed as open source software. A popular example of this technology is in the Samsung Galaxy S4, which allows photo capture simultaneously. Use of one camera and one lens In late 2012, Samsung announced its NX300 camera. Using just one (optional) lens, this camera can take 2D photos, 3D photos, or Full HD movies, simply by changing the mode. The optional lens is a proprietary, 45mm f/1.8 prime lens. The NX300 has two LCD screens in the optical path which are used to "black out" their respective half of the lens, sending a slightly different image to the sensor. Another method is used by Sony and Panasonic. With burst captures, the camera should be shifted sideways about 10 centimeters and the camera will choose the two best images with which to create a 3D MPO file. The depth is not as good, but can certainly allow the differentiation of what is in front and what is behind. Pentax and Kúla 3D have made stereoadapters, sometimes called beamsplitters, for stereoscopic photography with DSLR camera lenses.
