Temperature
Converting a setting does not establish doneness, safe storage or a safe experiment.
Visuals
A useful cooking image shows a difference you can act on: cut size, pan spacing, surface moisture or a stage in a method.
In practice
Compare the same ingredient under similar lighting. A darker surface may show browning, but it cannot by itself establish that food has reached a safe internal temperature.
Use the browning guide for surface changes and the source notes for the separate safety question.
Kitchen maths
Compare pan space
This compares flat circular bases only. Depth, usable base size and material can change the result.
