Abstract
Stereoscopic photography has a long history which started just a few years after the first known photo was taken: 1849 Sir David Brewster introduced the first binocular camera. Whereas mobile photography is omnipresent because of the wide distribution of smart phones, stereoscopic photography is only used by a very small set of enthusiasts or professional (stereo) photographers. One important aspect of professional stereoscopic photography is that the required technology is usually quite expensive. Here, we present an alternative approach, uniting easily affordable vintage analogue SLR cameras with smart phone technology to measure and predict the stereo base/camera separation as well as the focal distance to zero parallax. For this purpose, the StereoCompass app was developed which is utilizing a number of smart phone sensors, combined with a Google Maps-based distance measurement. Three application cases including red/cyan anaglyph stereo photographs are shown. More information and the app can be found at: <uri>http://stereocompass.i2d.uk</uri>

Stereoscopic photography has a long history which started just a few years after the first known photo was taken by Joseph Nicephore Niepce in 1826. 1849 Sir David Brewster β who improved the stereoscope technology invented by Sir Charles Wheatstone around 1832 β introduced the first binocular camera
Compass Smartphone Apps Before we look into the StereoCompass app development, we first want to elaborate a number of compass apps for the smartphone
Summary
A few decades ago, photography was a specific area for professional or enthusiastic photographers. The participation required decent financial investments and experience to produce technically appropriate photos. Nearly every smartphone user has a camera integrated in the phone, which often produces images of decent quality. The flagship smartphones of Apple, Samsung and Huawai produce very satisfying photos.
