värvikompensatsioon

Värvikompensatsioon, also known as color compensation, refers to the process of adjusting or correcting colors in an image or video to achieve a desired or more accurate representation. This is often necessary due to various factors such as the limitations of recording equipment, different lighting conditions, or the subjective perception of color.

The primary goal of color compensation is to ensure that the colors displayed are as close as possible to how they would appear in reality, or to meet specific aesthetic standards. This can involve correcting color casts, which are unwanted tints that affect the entire image, such as a blueish cast from shade or a yellowish cast from incandescent lighting. It can also involve adjusting the saturation, brightness, and contrast of specific colors to make them more vibrant or subdued.

In digital photography and videography, color compensation is typically performed using software tools. These tools allow users to manipulate the color balance, white balance, and individual color channels. For instance, adjusting the white balance aims to make white objects appear truly white, which in turn corrects the overall color cast. Color grading, a more advanced form of color compensation, is often used in filmmaking to create a specific mood or style.

The need for color compensation arises because cameras and displays do not always capture and reproduce colors identically to human vision. Environmental factors like the time of day, weather, and the type of light source significantly influence how colors are perceived. Therefore, color compensation is a crucial step in post-production to ensure visual consistency and achieve the intended look for an image or video.
