Exposure Adjustment is a two step process:
- Lightbox/Lens Compensation: Creates a compensation file for your model.
- CMOS Calibration: Adjust exposure by recalibrating the CMOS.
This tab creates a file that adjusts for differences between your
Light Box, Test Lens, and a good Reference Camera

Creating the Compensation File involves four steps. The software window provides clear, step-by-step instructions! Just follow the prompts and let the software do the work. As you move through each step, the active section highlights in red, and detailed guidance appears onscreen, making the process smooth and straightforward.
And remember—this is a one-time setup per model. After that, just move straight to CMOS Calibration.
The software is designed to make even advanced procedures like CMOS adjustment simple—whether you’re in a busy shop or working solo!
