What is gamma correction?
Gamma correction is the process of adjusting the brightness and contrast of a video to make it appear more natural. It compensates for the non-linear way that monitors and screens display light so that midtones, shadows, and highlights look more accurate.
Does gamma correction improve contrast?
Yes, gamma correction can improve contrast, especially in midtones, by adjusting the relationship between light and dark areas.
What is the difference between exposure and gamma correction?
Exposure changes the overall brightness uniformly across the image, while gamma correction specifically adjusts midtones without significantly affecting shadows or highlights.
What is the difference between gamma correction and tone mapping?
Gamma correction adjusts the brightness of an image to make it look more natural by changing the midtones. Tone mapping converts high dynamic range (HDR) images to a lower dynamic range (LDR) to display them correctly on standard screens.
