The subject of master thesis is the long exposure as a creative way of expression. In order to better understand and apply this photographic technique here are described settings that are crucial for using a long time exposure. So, terms such as exposure time, aperture, sensitivity and reciprocity law and the exposure itself are technically described and explained. There are also described photographic motifs which are used in long exposure techniques with emphasis on night photography and human movement. In this way it is shown how to use technical settings when using long exposures to get the desired result. In the practical part is shown the author's realization of photos based on researched principles and preferences for this type of photography. Practical part gives an insight into how a creative way of photographic expression applies long exposures techniques, primarily in the interpretation of night photography and human movement. These captured images are technically described and analyzed from the syntactic and technical standpoint. It gives an insight into how the different settings and conditions, when using long exposure as photographic technique, affect the result of photographic work of art.
