Observation records / Material surfaces
Surface texture changes how an object interacts with light, contact and wear.
01. Establishing a reference
Surface texture changes how an object interacts with light, contact and wear. Lighting direction affects the appearance of texture. A useful working note records the context and the purpose of the study. Keep the details that explain what was noticed, and distinguish them from ideas that emerged later.
Lighting direction affects the appearance of texture. This point should be read together with the stated reference and the conditions of the record.
02. Describing the setup
Roughness describes small-scale surface variation. When revisiting a series of observations, begin with the original context. Record the order of the work and keep the first descriptions alongside any later interpretation.

03. Reading the first observation
The next pass through material surfaces focuses on comparison. A coating and its substrate behave as a system. Look for the relationships between the details and retain enough context for another reader to understand the study.

04. Working with variation
Surface texture changes how an object interacts with light, contact and wear. Lighting direction affects the appearance of texture. A useful working note records the context and the purpose of the study. Keep the details that explain what was noticed, and distinguish them from ideas that emerged later.
A finish should be described with a measurement method. This point should be read together with the stated reference and the conditions of the record.
