Light sources and their use in cinematography practice
Pavelek, Tomáš ; ŠPELDA, Josef (advisor) ; MACÁK, Jiří (referee)
This thesis is written in the genre of manual with reflection of a problem and focuses on the importance of light as one of the main aspects of filmmaking and as a main tool for creation of an atmosphere. That are examples of the key expressions, which are used and described in the text: light ratio, light as a source of shadow, characteristic of the light, light perspective, color temperature, reflectance, skin tone, light design for film stock and digital camera. In order the problematic of lights sources with different color temperature is presented, so as the aspects of shooting low light chiaroscuro atmospheres, Inverse-square law usages, light source as a part of the frame, shooting in small scale locations and shooting with multiple cameras.

Technical tools of picture stylisation
Todorov, Simon ; MYSLÍK, Jiří (advisor) ; JÍCHA, Marek (referee)
This bachelor these is focused on the problematic of picture stylization thru the technical aspect. The stylization itself is not the concern of these theses. This work only deals with the technical tools and there influence in the final picture. It contains two main parts - time of production and time of postproduction in which are written the primary points of the process and the technics cinematographers applies. The tools are described gradually combined with the problems which may appear during the workflow. For each problem there in an explanation of how does the final picture change. Their consequences are also described, such as the job of cinematographer and his role in present times. In this these is also explained, brief-ly, the procedures of shooting and postproduction, presentation and archiving.

Stereoscopy and the Cinematographer
Gunaratna, Vidu ; SMUTNÝ, Vladimír (advisor) ; MYSLÍK, Jiří (referee)
The thesis is a study of stereoscopy from a cinematographer's point of view. It views stereoscopy in it's entire spectrum of today's use - from rides in theme parks, over commercial narrative films, to documentaries with a cultural value. It briefly takes a look at the early theories of binoculars, the early stages of stereoscopy discovery and stereophotography. Next it briefly focuses on the history of stereoscopy in cinema from its beginning, to it's renaissance in the 1950's up to today. Thereafter the thesis continues with a description of the principles of depth perception, with keywords like disparity, parallax, convergence and accommodation. It mentions the importance of non-stereoscopic depth cues to the process of stereopsis. The next part concentrates on the stereoscopic window, which is analogical to the frame and it's borders in conventional cinema. It investigates the screen size, the distance limit of the far plane and stereoscopic window violation. It continues in breaking down the stereoscopic image and factors that influence the size perception of objects and figures in it's space, as well as analyzing the perception of the whole image depending on the viewer's position to the screen. Attention is given to a special case of stereoscopy - orthostereoscopy. Depth bracket, native parallax and terms such as stereo comfort zone, depth budget and depth bracket are defined to create an understanding of the importance of the concept of the depth chart. The aesthetics of depth is demonstrated on a few recent stereoscopic films. A general overview of equipment for stereoscopy follows - rigs, 3D monitors and software. The thesis continues in discussing the tools of the cinematographer divided into two groups - non-stereoscopic and stereoscopic. The non-stereoscopic are linear and colour perspective, atmosphere blur, focus and camera movement. While the stereoscopic tools are interaxial distance and convergence. The cases of hypostereoscopy and hyperstereoscopy are understood as tools of the trade as well. The next chapter is dedicated to the specifics and limitations of stereoscopic imaging - the necessity of perfect pairing of cameras, lenses, the specifics of framing for stereoscopy, issues related to the mirror in the rigs, lighting and use of optical camera filters. The next part of the thesis briefly covers related topics that have an impact on the image as well. Namely set design, post-production, with stress on colour grading, and various stereoscopic projection systems, including autostereoscopy. The last part of the thesis is an interview with cinematographer Andrew Lesnie, ACS, ASC who shares his experience on shooting the Hobbit. The conclusion is a reflection on the question, if stereoscopy is a tool and it also tries to estimate the future of stereoscopy in film and television.

Filming underwater
Dvořáček, Šimon ; BRABEC, Jaroslav (advisor) ; HYNEK KRÄMER, Kristian (referee)
The topic of this thesis is "under water shooting ." Text deals with the theoretical and practical problems associated with underwater filming. Given the empirical type of the thesis, the text focuses on the personal experience gained during the filming of underwater scenes of Menandros & Thais movie, I worked as director of photography for. All the experience I gained during the preparation and the actual filming should be benefit to those who will in the future address this issue.
The first part of the thesis is a brief history and theory of diving. It describes development of diving equipment from the the beginning until today and explaines the theoretical minimum for underwater filming.
The second part is a description of underwater battle to the detail, where I worked as a director of photography on the preparation, implementation and finalization. This chapter is divided into five parts. The first part deals with the initial concept of underwater scenes. The second part describes the preparation for filming. The third and fourth parts deal with the implementation from rehearsals up to filming. The last, fifth part focuses on the reflection of the underwater scene. Here I outline what was brought to the reality from the concept.

Night in film
Marek, Lukáš ; MACÁK, Jiří (advisor) ; ŠOFR, Jaromír (referee)
The night is one of the ways to learn about the presence of light. Similarly, the present thesis is one of the sources revealing something substantial about night and its presence around us. The actual theme of night is approached on the basis of its impact on both the human eye and the film material, or basically any other photosensitive element. This work has been drawn up and is comprised of several parts. The first part deals with the actual definition of the concept of night in encyclopaedic terms and night in general, its role in mythology, and it ends with the description of technical and psychological details of night scenes. The next part discusses the most typical adaptations and interpretations of night on the screen. It provides a list of instructions regarding the preparations of such an atmosphere, specifies the best shooting approaches and techniques and what is to be left for the process of post-production in a film laboratory. The text is complemented with numerous illustrations in the form of graphs, photos, exported film samples and picture instructions.

Cameras for digital cinematography, specifications and quality measures
Polách, Martin ; JÍCHA, Marek (advisor) ; KOŠŤÁL, Emil (referee)
This thesis is about essential digital cameras and technologies, which are used by directors of photography for shooting feature films, commercials and television content. I focused mainly on cameras, that are available to the public in your 2012, which are for example Arri Alexa, RED EPIC, Sony F65, Phantom FLEX, Phantom 65 and few more semi-professional cameras. In my thesis I also look back on the beginnings and history of digital cameras from 1990?s, when first cameras emerged that were at least able to compete with film negative, and on the development of second generation of digital cameras as Panavision Genesis, Arri D20-D21 and RED ONE. Part of my work is also devoted to technical properties and specifications, which are required from current high-end cameras.
