The reasoning behind the tools
Where an engine's result depends on an idea that's easy to get wrong, such as what a histogram actually tells you or why "equivalent" focal length means more than one thing, that idea gets its own resource: a durable explanation tied back to every engine it supports, not a one-off aside buried inside a single tool.
What belongs here
A resource earns its page by supporting more than one engine and by having a distinct thesis of its own: depth-of-field and viewing-condition limits, exposure and dynamic-range tradeoffs, sensor and lens resolution, browser-local image analysis and privacy, print resolution and viewing distance, flash falloff, and responsible sharpness or noise interpretation are the kinds of ideas that qualify. A resource is written independently for ImageReason's own tools and inputs, never adapted from another site's explanation of a similar concept.
