The perception of gloss: a review

Area of Science:

• Visual perception
• Surface science
• Psychophysics

Background:

• Gloss, a visual property of surfaces, was historically studied assuming it was an inherent physical characteristic.
• Early research focused on reliable measurement scales, treating gloss as an objective physical property.
• Models based on inverse optics for gloss perception proved intractable and inadequate.

Purpose of the Study:

• To review the historical and current research on gloss perception.
• To track the evolution of theories and approaches in gloss studies.
• To highlight the renewal of interest in gloss perception over the last decade.

Main Methods:

• Historical literature review of gloss research.
• Analysis of theoretical shifts from physical properties to perceptual interactions.
• Examination of technological advancements enabling new experimental techniques.

Main Results:

• Recognition that gloss perception is a complex interaction of illumination, surface properties, and observer factors.
• The field has shifted from purely physical measurements to understanding perceptual mechanisms.
• Technological advancements have facilitated new experimental approaches and measurements.

Conclusions:

• Gloss perception is not solely an inherent surface property but a complex perceptual phenomenon.
• Current research acknowledges the interplay of multiple variables in how gloss is perceived.
• Renewed interest, driven by technological progress, is advancing the understanding of gloss perception.
