Chromatic Aberration
A lens defect causing color fringing (typically purple or green halos) at high-contrast edges in photographs, resulting from different wavelengths of light being focused at slightly different points.
What is Chromatic Aberration?
Chromatic aberration appears as color fringing along sharp edges — a red product edge might show purple/blue fringing on one side. It's more pronounced in lower-quality lenses, at edges of the frame, and at wider apertures. For product photography, chromatic aberration is particularly problematic for images used at zoom resolution, where buyers can clearly see the fringing at product edges. Modern cameras and editing software (Adobe Lightroom, DxO) offer automatic chromatic aberration correction.
E-Commerce Relevance
Chromatic aberration at product edges is clearly visible at Amazon's zoom level — buyers associate color fringing with poor photography quality, reducing trust in the product's quality.
