- Refers to still images produced from radiation-sensitive materials (sensitive to light, electron beams, or nuclear radiation), generally by means of the chemical action of light on a sensitive film, paper, glass, or metal. Photographs may be positive or negative, opaque or transparent. The concept does not include reproductive prints of documents and technical drawings, for which descriptors found under "" are more appropriate. The concept may include photographs made by digital means.
- Landscapes with densely built-up districts and settlement areas and with distinctive skylines.
- Buildings or devices with sails or vanes that turn in the wind and generate power. The devices operate by means of a rotating shaft on which sails are mounted or placed at an angle so that the force of wind against them causes rotation, which in turn produced energy. Windmills were historically used chiefly in flat districts for operating a mill to grind grain or pump water; the older and most characteristic European form consists of a conical mill-house with a dome or cap supporting four sails. Modern devices tap the wind to produce electricity by using a disk of sails mounted on a framework.
