Gammakorjauksella

Gammakorjauksella, a Finnish term, translates to "gamma correction" in English. It refers to the process of adjusting the luminance or gamma of an image or video signal. This adjustment is crucial because electronic displays, such as monitors and televisions, do not always reproduce brightness levels linearly. Different display technologies and their inherent characteristics can lead to images appearing too dark or too light. Gamma correction aims to compensate for these non-linearities, ensuring that the displayed image accurately reflects the original brightness information.

In digital imaging, gamma correction is often applied to the pixel values. A gamma value greater than 1.0 will brighten darker areas of an image more than lighter areas, while a gamma value less than 1.0 will have the opposite effect. This process is important for various applications, including photography, video editing, and computer graphics, where accurate color and brightness representation is essential. Without proper gamma correction, images might appear washed out, overly dark, or inconsistent across different viewing devices. The goal is to achieve a natural and pleasing visual representation that matches the creator's intent.
