Coating Trial Photographs: Keep Image Processing Consistent

Editing settings can change the apparent contrast, colour and clarity of a coating comparison. Preserve the original photographs and apply a consistent, disclosed processing approach when images are used as evidence.

Updated · NANOLAB Knowledge

The key distinction

Exposure and viewpoint matter during capture, while sharpening, saturation and local adjustments matter afterward. A visually attractive presentation can become misleading if the before image and after image receive different treatment. Decide which processing is necessary for faithful display and keep that process separate from marketing embellishment.

Practical checks

  1. Retain original files with their sample identities and capture records.
  2. Apply the same appropriate processing settings to comparable images.
  3. Disclose material adjustments and keep an unprocessed reference available for technical review.

Example

Illustrative example: the after image receives extra clarity and saturation while the before image remains unedited. The resulting presentation may imply a larger surface improvement than the photographs support. A fair comparison uses equivalent processing and explains any unavoidable difference in capture conditions.

Scope and limits

Do not use selective editing to remove defects, strengthen water beads or change a sample's apparent finish. This guide does not require every photograph to be visually identical; it requires differences in image treatment to remain transparent when the images support a product-performance claim.

Coating Trial Histograms: Keep Bin Choices Visible

A histogram can help show the distribution of coating-trial results, but its appearance depends on how values are grouped. State the bins and avoid choosing a grouping solely because it makes a product look more consistent.
