HELIOGRAPHY Meaning and
Definition
-
Heliography is a term with multiple definitions depending on the context in which it is used. In general, heliography refers to the process of recording or capturing images using the sun's rays or sunlight.
In the field of photography, heliography refers to an early photographic technique developed by Joseph Nicéphore Niépce in the early 19th century. This technique involved using a camera obscura and bitumen-coated plates to capture images. The plates were exposed to sunlight, and the bitumen areas that were struck by the sunlight would harden, while the areas shielded from the light would remain soft. These plates were then washed with solvents, leaving behind an image that could be considered a precursor to modern photographs.
Heliography can also refer to a process used by astronomers to create maps of the surface of the moon or other celestial bodies. In this context, heliography involves capturing images of the celestial object using a telescope and recording specific features, such as craters and mountains. These images are then compiled to create a detailed map or chart of the surface.
Furthermore, heliography can be used to describe the practice of creating drawings or designs by using the sun's rays to burn or etch images onto various materials, typically through the use of a magnifying glass or other focusing devices.
Overall, heliography encompasses various processes and techniques that involve utilizing sunlight to capture, record, or create images.
