Documentary visible-light photograph
Records light through a camera or detector in a way that can preserve a familiar visible-light relationship.
Boundary: Still involves exposure, optics, calibration, framing and processing.
Outerspace · Representation Gallery
What kind of image is this?
A gallery without borrowed imagery: five representation classes, each with a different evidence boundary.
Multiwavelength composite
Combines or maps multiple bands into one visible image.
Boundary: Display color can encode non-visible wavelengths; legend/context matters.
Scientific visualization
Turns measured or simulated data into a graphic form.
Boundary: Geometry and color may represent variables rather than literal appearance.
Artist concept / reconstruction
Communicates a scientifically informed scene that could not be directly photographed as shown.
Boundary: Must be labeled as an interpretation, not observational evidence.
Simulation output
Represents results of a computational model.
Boundary: Shows model behavior under assumptions; it is not a direct recording of the universe.
Documentary anchor
Earthrise
NASA identifies Earthrise as a photograph made by William Anders during Apollo 8 lunar orbit. Here it anchors the difference between a documented viewpoint and a reconstructed global diagram.
No-media rule for this candidate
Authored diagrams only.
No third-party or random web image has been copied into this delta. That keeps rights review simple while the evidence architecture is established.
