DESCRIPTION OF CONTENTS
Stereoscopy is recently very popular method which depicts objects and environment in three-dimensions. 3D (stereoscopic) projection is used in movies or computer games, nevertheless, when compared to 2D movies, it is not used very frequently and the amount of stereoscopic movies and materials is much lower. Hence, new materials are required to be prepared. The chemistry education is not exception. Hence the new stereoscopic materials for chemical education are under preparation. Some factors and parameters affecting the stereoscopic movies preparation and treatment (at amateur conditions) were tested and optimized. It was showed that the optimal ratio (ratio between distance of objects from camera and distance of objectives of camera) is greater than 1:12 (for distance less than 5 m), but ratios up to 1:8 are also acceptable. Keying (Chroma key) showed to be also possible. Zooming led to the object deformation and it is not recommended to use to movies were the proportions of the objects are important.
Already long gone are times when teachers suffice boards, chalk and cane to teach his students everything. At present, however, we witnessed considerable boom in science and technology, which together offer us applications that until recently seemed to be beyond the capacity of mankind. Who would have a few decades ago believed that even on Mount Everest it would be possible to have access to the latest news from thousands of kilometers away home from a device of the size of boxes of crackers (today we call smart mobile phone - smartphone), who would have believed that we would be able to talk with a friend kangaroo from Australia in real time at fractional cost, or that we could see every pinhead on television with HD resolution and that would be affordable a TV with a diagonal of more than 100 inches, and weight of the television would be that of a typical purchase.
Even though the teacher is still the most important element of education, thanks to the aforementioned progress in science and technology, present time offers a number of options for them to teach more effectively. A projector is already a common part of Czech schools and interactive whiteboard become pervasive.
REVIEWER’S COMMENTS ON THE PUBLICATION
The article is about possibilities of creation of the stereoscopic materials to learn chemistry. The article is clear. This topic is corresponding with our project. The education and training of professors is nowadays very prior. And the videos and other stereoscopic materials are the way how to increase the interest in teaching chemistry. Lots of people don’t want to work in the area, where are lots of traditional approaches, old materials, to modern technologies. So this can help them to work in this section. Due to the popularity of 3D video, it has been decided to create them as a suitable motivating element in teaching chemistry, where it can help out with the display structures of various substances or organization equipment. In the first phase there have been tested and found suitable parameters for shooting in amateur conditions similar to the situation in the laboratory of the authors. They observed ratio of the distances from the camera lenses to the target. They revealed that, compared to preferred ratio of 1:20, for chemical objects ratios in the range of 1:12 to 1:8 are also applicable. This finding resulted in a limitation of camera movement towards the object and away from it, which is recorded and restrictions on focusing when shooting an object detail. Further, possibility was tested of implementation of keying in shots that can be despite the considerable time complexity in its implementation and use, that are keyed both images at once. It is also shown that in choice of framing the scene (placement of objects) and of action, number limitations exist that must be taken into account. Indicative survey aimed at identifying pupils' preferences regarding to the method of video processing showed interest in the form of an entertaining approach to these images.

Message: Text is published in quarterly journal for education. The Articl reacts to boom in field of science and technics which should school react also too. Possibilities of using progress are huge.
Authors are showing right way. Disposition of approaching the reality of sensed picture as good help in creation of more real imaginations. Illustrativ demonstrations are very helpful. Stereoscopy is an interesting way in the future. In this Article are showed also directions how to make proper conditions for perception. Discuss also limited sources of stereoscopic pictures and show way how to make own records. The 3D Pictures are very interesting variegation of chemistry classes.
They are unusual, new and catch intensively attention of students. The problem of using them is time constingness of making these models. But in the future may technologies more develop and stereoscopic materials should be more at hand.
Engaging of new technologies to chemistry classes is the modern trend. But teacher is still the main source of informations. Chemistry teacher´s work with new technologies has sure huge effect to motivation students on science. This article deals with very actual problems in field of education and chemistry. I regard it as relevant and helpful.
