Multi-projector calibration is the process of matching brightness, white balance, gamma and color across multiple projectors after physical and geometric alignment has been completed. Even identical projector models can show visible differences because of operating hours, optical conditions, power modes and unit variation. This guide explains how to calibrate professional multi-projector systems for immersive, mapping, museum, dome and large venue applications.

Projector color calibration is the process of adjusting and verifying image parameters so that projected content is reproduced consistently and as close as possible to the intended reference. This guide explains how white balance, grayscale tracking, gamma, color gamut, black level, brightness and viewing conditions interact, and why professional calibration should evaluate the complete projection system rather than a single picture setting.
