The purpose of the research was to find connections between different technical options within the capabilities of photographic equipment with an emphasis on the lens and the challenges of how to use them in individual genres to achieve the most favorable or alternative specific results imagined by the photographer.
We reviewed the spectrum of physical and other challenges in photography, for which there are several technical and technological solutions that land in the photographer's hands as equipment that he manipulates and uses to create the desired message in a completely different sphere. This review and consideration of where a given photographic equipment offers the widest possibilities of manipulation leads us primarily to the lens, or for that reason several lenses, which accompany many photographers and differ primarily in terms of focal lengths.
Searching for a connection between the expression that the focal length gives in the chosen genre, we tried to either define or measure it in a technical way and, on this basis, explain how it affects the result. We approached this task with a set of genres, within which we recorded wire models and specific genre scenes with different focal lengths for comparison. In addition, by analyzing the ratio of the area of the surfaces in the wire model, we explained where we will find a pronounced influence of the focal length on the perspective in photography.
Through the research, we explored the purpose of different cameras and lenses. Based on experimental work, we came to the result that all different focal lengths have their own genres in which they perform better. But these conclusions are not set in stone, because despite the chosen genre, the photographer can go beyond them when he wants to convey a message in a different, imaginative way.
