Abstract

In the 21st century, the form of presenting information plays an incredibly important role in arousing interest in research problems. Stereoscopy is among the imaging techniques that have evoked much interest in the recent years. Its numerous applications that can be observed in various fields (such as medicine, space science, law, marketing, or entertainment industry) suggest that we should also use this technology for didactic purposes. The aim of the article is to discuss the process of creating three-dimensional photography and the opportunities offered by stereoscopy, which makes it possible to obtain images with depth effect and impression of solidity. The authors describe different ways to obtain three-dimensional images and the devices applied in the process, as well as techniques of presenting three-dimensional material to a wider audience. The methods of free-viewing (the oldest method of viewing stereoscopic images), anaglyph (a simple method applied in printing and displaying static images and movies on screen), lenticular raster (employing a series of narrow vertical cylindrical lenses), and stereoscopy (in which mirrors, lenses, prisms, or filters are used) are discussed. Also, the application of computer technology is reviewed and the ways in which stereoscopy can benefit from this medium owing to the use of LCD shutter glasses. Contemporary technology offers considerable opportunities, at the same time posing ever-increasing demands, which are mentioned in the paper, too. Teaching is most effective when information is received through multiple channels, combining verbal and visual messages. Owing to 3D images, the recipients grasp more information details, remember them longer, and are more interested in the message content. Creating didactic presentations with the use of three-dimensional photographs or films is presented as a way of arousing interest, allowing direct participation in the cognitive process, and facilitating the reception of the transmitted content.
