Contrast Detection Autofocus
An autofocus method that analyzes raw pixel brightness steps on sensor data, hunting back and forth until edge contrast reaches its absolute peak.
Detailed Analysis & Visual Theory
Contrast Detection Autofocus (CDAF) represents an essential cornerstone of photographic expression, visual narrative, and technical mastery.
