This document is the user manual for the Color Balance Lens (CBL lens), which is designed to help users take digital photos with natural true color under any lighting conditions.
The CBL Color Balance Lens is a photographic accessory that provides a 100 % homogeneous spectrum reflection, acting as an 18 % gray reference for both white‑balance and exposure measurement. By placing the lens in front of the camera, photographers can capture true‑color images directly, eliminating the need for later color correction.
The guide covers handling, mounting the wrist strap, setting up various camera models, and measuring light under different conditions such as sunny, cloudy, indoor, and studio environments. It also includes safety precautions, packaging details, and technical specifications for the three lens sizes.
