How Colour Temperature Influences the Viewer

A small – visible part of the electromagnetic wave spectrum is ** perceived by our eyes as light. Intensity and brightness, quality, direction and the most important property in their diploma thesis, ** colour temperature, are amongst the most important ** optical properties. These results are achieved with the correct ** white balance setting. A video where frames with one colour temperature are interwoven with another is rather unpleasant to watch.

Problem

A small – visible part of the electromagnetic wave spectrum is ** perceived by our eyes as light. Intensity and brightness, quality, direction and the most important property in their diploma thesis, ** colour temperature, are amongst the most important ** optical properties**. White light is obtained when individual waves are correctly distributed in the electromagnetic wave spectrum.

This is the sum of all colours. A correct or continuous spectrum can be achieved by heating the light source. This source is represented by light bodies, to which colour temperature can be assigned.

The degree of colour temperature is generally expressed in kelvins. When the same change in colour temperature in kelvins does not also mean the same changes in colour, we use the reciprocal unit mired. White light, which represents the sum of all spectral colours of visible light, disperses into individual parts when passing through a prism, where the main colours can be clearly observed: ** red, orange, yellow, green, blue, indigo and violet**.

In photography and video, it is crucial that the captured colours are as we see them in reality.

Results

These results are achieved with the correct white balance setting. A video where frames with one colour temperature are interwoven with another is rather unpleasant to watch. When using cameras, we must therefore correctly calibrate and set the white balance, as this captures the correct original image and avoids more demanding colour correction in post-production.

To balance the colour temperature of different light sources, various colour foils, ** gels** and ** filters** are used. They are also used for creative purposes. Alongside colour correction, we also know ** colour grading**, which determines the appearance of the video.

It depends on what we want to achieve with it. With correctly chosen grading, we can additionally influence the viewer's emotions and ** perception** and emphasise the message of the video. In the diploma thesis, several films were analysed that demonstratively use colour temperature and colour grading as an additional element for the ** message of the story**.

As part of the diploma thesis, a short film entitled Lottery Fever was also shot and analysed. The script was briefly summarised and creative decisions explained. They also described how they approached lighting and what equipment was used during filming.
