What does it mean that photograph as capture?

A photo of a whiteboard, sketch, or physical artifact is a legitimate capture method — and for spatial, visual, or environmental information, it is the superior one.

Example: You're in a workshop. The facilitator has built a complex system diagram across three whiteboards — arrows, clusters, annotations, color-coded zones. You could spend fifteen minutes transcribing it into text. Or you could take three photos in four seconds, preserving every spatial relationship, every arrow direction, every color distinction. The photos capture what text fundamentally cannot: the topology of the idea.

Try this: Today, capture three things as photographs that you would normally try to describe in text: a whiteboard, a physical arrangement, a diagram, a book passage with margin notes, or an environment that triggered an idea. For each photo, add one line of text context (date, why it matters, what you were thinking). At the end of the day, review all three. Notice how much information the photos preserved that your text description would have lost.
