The spheres in the
Difference viewports show the result of subtracting the task image from the solution image:
- On the left: Task minus Solution.
- On the right: Solution minus Task.
For better visibility, the result is multiplied (brightened) by a factor of 5.
If the task and solution images match perfectly, the areas with spheres will appear completely black.
Bright, colored areas in
Task minus Solution indicate where your studio lacks sufficient lighting to replicate the illumination of the selected virtual scene. To achieve a more accurate result, you can add additional light sources in the highlighted areas and repeat the studio calibration.
Bright, colored areas in
Solution minus Task highlight regions where your studio's lighting exceeds what is required by the task. In most cases, this may be the result of insufficient light sources in the areas required for the selected virtual scene. CyberGaffer will attempt to achieve the optimal solution using the available sources near these "empty zones," which will lead to an increase in the Differences.
