Coating Appearance Photos: Lock Exposure Before Comparing Panels
Automatic camera adjustments can make two surfaces appear different even when their appearance is similar. A comparison needs consistent capture conditions.
Updated · NANOLAB Knowledge
Practical approach
Keep lighting, camera position, exposure and relevant processing settings controlled. Include a reference view and preserve the original files.
A darker exposure can make reflections appear richer, while a brighter exposure may hide subtle haze.
Decision limits
Do not use selectively edited images as measurement evidence. Photographs can document appearance but should be interpreted within their capture conditions.

Coating Test Panels: Keep the Backing Consistent
The support behind a sample can affect how a test is performed or observed. Unrecorded backing changes introduce another variable into comparisons.
