Re-examining the Traditional Principles of Cinematography of Modern Movies : a Case Study of Children of Men and Clerks IIHåkansson, Cornelia January 2013 (has links)
This thesis addresses the principles of cinematography and their significance for the visual outcome of a film. The purpose is to examine the importance of the principles for modern film and this is done through a study on how the principles are used and not used in the films Children of Men and Clerks II. The two films investigated are both known for being experimental and modern in their use of cinematography, and was therefore found suitable for this thesis. The limitation with this study is that only the four main principles of cinematography are analysed: camera angles, framings, points of view and camera movement, and they are only analysed in one shot from each film examined. In the results, the four main principles were investigated when and when not applied in the specific shot from each film. In the film Children of Men the breaking of the principle of point of view was most central, but the principle of framings and camera movement were in some cases also not applied. The only principle actually followed in this shot was the principle of camera angles. In the other film examined, Clerks II, the breaking of the principle of camera movement and camera angles was most central together with the breaking of the 180 degree rule. The principles that were followed in this clip were framings and points of view. In the conclusion the results were discussed and also the possibility of effects on the viewer, when breaking the principles. Different ideas of possible effects on the viewer were presented, but they all had disorientation in common. The possible outcome of disregarding the principles of cinematography ended up being misleading the viewer away from the narrative.

Perspectives of multimode fibers and digital holography for optogeneticsCzarske, Jürgen W., Haufe, Daniel, Koukourakis, Nektarios, Büttner, Lars 08 August 2019 (has links)
Optogenetic approaches allow the activation or inhibition of genetically prescribed populations of neurons by light. In principle, optogenetics offers not only the ability to elucidate the functions of neural circuitry, but also new approaches to a treatment of neurodegenerative diseases and recovery of vision and auditory perception. Optogenetics already has revolutionized research in neuroscience. However, new methods for delivering light to three-dimensionally distributed structures e.g. in the brain are necessary. A major hurdle for focusing light through biological tissue is the occurring scattering and scrambling of the light. We demonstrate the correction of the scrambling in a multimode fiber by digital optical phase conjugation with a perspective for ptogenetics.
