Gamma correction and linear workflows
- [Instructor] Gamma is the contrast curve of an image, and gamma correction is very important for photometric or linear workflows. It's a numerical value representing the shape of that curve. Gamma values below one increase contrast, and values above one decrease the contrast. One application of gamma is a way of compressing image data. Human eyes are more sensitive to relative differences in darker tones, and we are less sensitive to differences in brighter tones or highlights. Gamma correction takes advantage of this non-linear response to optimize image storage and display. Standard image files encode more data in the blacks, compressing the highlights, and when the image is displayed, the gamma is decoded and the image contrast is restored. A digital camera is also more sensitive to shadow areas, just like our eyes. If we looked at that camera data in raw form, with gamma value interpreted as one, it would look washed out. But image viewing and editing applications normally…
