Definition
Transfer functions are mathematical formulas that translate image signal values from one representation to another. They determine how brightness and contrast information is encoded and decoded throughout imaging pipelines.
Purpose
Because cameras, editing software, and displays interpret brightness differently, transfer functions ensure signals remain visually consistent when converted between formats.
Types
Common transfer functions include gamma curves, logarithmic curves, and perceptual encoding models. Each prioritizes different aspects of image fidelity.
Professional Importance
Understanding transfer functions allows creators to maintain tonal accuracy across production workflows.
