Prototyping

Use photographs as design evidence

A useful image includes enough context to support an observation.

Sketch sheets, a caliper and metal samples on a product designer’s desk.

Capture the relevant view

Photograph the feature being discussed from a position that makes the issue understandable. Include the prototype identity in the accompanying record and use appropriate reference information where needed. A dramatic close-up can obscure scale or orientation. Avoid presenting a photograph as a substitute for a measurement when the decision depends on quantitative evidence.

Keep captions honest

Describe what the image shows and which conditions apply. Record whether the photographed sample was modified, unfinished or representative only of appearance. Keep the original file and link it to the relevant test or review. A collection of clearly captioned images helps remote colleagues understand a prototype without assuming that every visible detail is an approved design choice.

A practical review checklist

  • Capture orientation and context.
  • Link the image to a revision.
  • Describe visible limitations.
