Definitions / Imaging methods
An image records a projection of a scene through a particular optical and sampling process.
Overview
Exposure time affects motion blur.
Method
Pixel count alone does not determine image quality.
Observations
A calibration target provides a repeatable reference.
01. Establishing a reference
An image records a projection of a scene through a particular optical and sampling process. Contrast depends on both the scene and the imaging system. 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.
Contrast depends on both the scene and the imaging system. This point should be read together with the stated reference and the conditions of the record.
02. Describing the setup
Exposure time affects motion blur. 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 imaging methods focuses on comparison. Pixel count alone does not determine image quality. Look for the relationships between the details and retain enough context for another reader to understand the study.
