Comparing swatch photos: colour depends on the image setup
A swatch photograph records a colour sample through a camera and image workflow. Differences between two photos can come from lighting, viewing angle or editing, as well as from the sample. A photo is not a colour measurement by itself. [1]
KEY TAKEAWAYS
- Record sample identity and photo conditions separately.
- A colour cast can change the apparent shade. [1]
- Retain originals alongside edited comparison images.
Capture conditions
Adobe’s product-photography guidance discusses white balance and repeatable angles. For a nail-colour comparison, note the light source, background, camera or phone and angle. These records help identify which conditions changed; they do not make an uncalibrated image a laboratory measurement. [1]
Editing history
Keep an original file and identify adjustments in the comparison record. Cropping a background and changing colour are different edits. Avoid treating a polished promotional image as an untouched record if its processing is unknown.
Compare one variable at a time
Start with the same finished sample and repeated setup. To compare angles, keep light, background and image processing constant; to compare lighting, keep the angle constant and label each light source. If creator, setup and editing all differ, classify the images as different presentations instead of treating their colour difference as a measured product difference.
