Reading diagrams / Imaging methods

An image records a projection of a scene through a particular optical and sampling process.

Overview

Exposure time affects motion blur.

01. Establishing a reference

An image records a projection of a scene through a particular optical and sampling process. Pixel count alone does not determine image quality. 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.

Pixel count alone does not determine image quality. This point should be read together with the stated reference and the conditions of the record.

02. Describing the setup

A calibration target provides a repeatable reference. 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. Contrast depends on both the scene and the imaging system. Look for the relationships between the details and retain enough context for another reader to understand the study.
