underlight

Underlight is a term used in various fields to describe light that is directed or reflected from below, rather than from above. In architecture and design, underlight refers to lighting fixtures that are installed beneath surfaces, such as tables, shelves, or walls, to illuminate objects placed on or against them. This type of lighting is often used to create a soft, diffused glow that enhances the appearance of items without casting harsh shadows. Underlighting can be achieved using various lighting technologies, including LED, fluorescent, and incandescent bulbs, and is commonly employed in retail displays, museums, and home decor to highlight products or artworks.

In photography, underlight refers to the light source positioned below the subject, which can be used to create unique lighting effects. This technique is often employed in studio photography to add depth and dimension to images. Underlighting can also be used in nature photography to capture the play of light on water surfaces or foliage.

In the context of underwater photography, underlight refers to the natural or artificial light that illuminates the underwater environment from below. This can include sunlight filtering through the water's surface, as well as artificial lighting used by divers or underwater cameras to capture images of marine life and underwater landscapes.

In astronomy, underlight refers to the faint light that is emitted or reflected from below the surface of celestial bodies, such as planets or moons. This light can provide valuable information about the composition and structure of these bodies, and is often studied using specialized instruments and techniques.
