Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Summary</title> <sec id="sca21201-sec-0001" sec-type="section"> <p>Surface textures of a large collection of photographic papers dating from 1896 to the present were measured using a laser scanning confocal microscope (LSCM) with four different objective lenses. Roughness characterization parameters were calculated from the texture measurements and were compared with gloss measurements. Characterization by the area‐scale fractal dimension (Das) and the area‐scale fractal complexity (Asfc) provided the strongest correlations between gloss reflectance and surface texture. The measurements with the 5× and 10× objectives, which contained many large‐scale, spiky measurement artifacts that distorted the measurement, resulted in the strongest correlations (R² &gt; 0.8) compared to the 20× and 50× (R² &lt; 0.5). The presence of spiky artifacts in the measurements, which increases when the magnification of the objective lens is decreased, appears to amplify surface features in such a way to improve the correlations.
