Abstract
V diplomskem delu je predstavljeno široko področje osnov in pojmov, ki so pomembni za predpripravo in izdelavo kvalitetnega končnega video izdelka. V delu je opisana svetloba in z njo povezani pojavi, ki so lahko ob njihovem poznavanju in zavedanju dobro izkoriščeni, v nasprotnem primeru pa lahko predstavljajo velik problem za kvaliteto posnetka. Sledi opis zaznavanja svetlobe skozi lastnosti človeškega očesa in kamere ter razlike med njima. Na video snemanjih so pogosto uporabljeni umetni svetlobni viri različnih vrst, lastnosti in kvalitete. Slednja je lahko izmerjena in opisana z različnimi standardi, med katerimi je tudi TLCI. Za konec sta predstavljena še postavitev luči na snemanjih ter postprodukcija posnetkov in izdelava LUT-ov. V praktičnem delu zaključnega dela so bili narejeni avtokorekcijski LUT-i za različne umetne vire svetlobe na podlagi meritev TLCI, katerih namen je skrajšati čas postprodukcije in olajšati delo koloristom na podlagi uporabljenih luči za osvetljavo na snemanju.

Title:Video color correction based on TLCI measurements
Abstract:
The thesis presents a wide area of basics and concepts that are important for preparation and production of a high-quality video product. The light and associated phenomena are described, which can be either exploited based on knowledge and awareness, or, in the opposite case, present a major problem for the quality of image. Next the perception of light through the characteristics of human eye and camera is described, and the differences between them. At video shootings artificial light sources of various types, characteristics and qualities are often used. The quality can be measured and described using various standards, including TLCI. Finally, the placement of lights on sets, post-production of video material and production of LUTs are presented. In the practical part of the thesis autocorrection LUTs were made for various artificial light sources based on TLCI measurements, the purpose of which is to shorten the time of post-production and make the colourists' job easier based on the light sources used at the video set.

Keywords:TLCI, LUT, colour correction, light
