In cinematography, butterflies (also known as overheads) are structures on which materials are mounted so as to control lighting in a scene or photograph.Materials commonly used on butterflies include: flags (black, opaque materials), nets (layers of neutral-colored bobinette), and diffusions (translucent white materials of different densities) for the purposes of blocking, dimming, and ...
Butterfly lighting, named for the butterfly-shaped shadow under the nose, the butterfly lighting pattern is created when the light is above and in line with the camera. Split lighting, where the main light is placed off to the side of the subject at about 90 degrees and positioned at face height or slightly above.

The butterfly eye is similar to the average insect eye in that it is composed of numerous ommatidia. Each butterfly ommatidium contains nine photoreceptor cells with generally each cell using a single opsin. [6] With a UV sensitive opsin the butterfly can see UV light and respond maximally to ultraviolet light at approximately 350 nm. [6]
The scales on butterfly wings are pigmented with melanins that can produce the colours black and brown. The white colour in the butterfly family Pieridae is a derivative of uric acid, an excretory product. [13] [40]: 84 Bright blues, greens, reds, and iridescence are usually created not by pigments but through the microstructure of the scales.
The brilliant iridescent colors of the peacock's tail feathers are created by structural coloration, as first noted by Isaac Newton and Robert Hooke.. Structural coloration in animals, and a few plants, is the production of colour by microscopically structured surfaces fine enough to interfere with visible light instead of pigments, although some structural coloration occurs in combination ...
The paper protected the flame from the wind. Burning oil in a stone, metal, or ceramic holder, with a wick of cotton or pith, provided the light. They were usually open on the top and bottom, with one side that could be lifted to provide access. [2] Rapeseed oil was popular. Candles were also used, but their higher price made them less popular.
