In optics, a diffuser (also called a light diffuser or optical diffuser) is any material that diffuses or scatters light in some manner to transmit soft light.Diffused light can be easily obtained by reflecting light from a white surface, while more compact diffusers may use translucent material, including ground glass, teflon, opal glass, and greyed glass.
In real life terms what this means is that light is reflected off non-shiny surfaces such as the ground, walls, or fabric, to reach areas not directly in view of a light source. If the diffuse surface is colored, the reflected light is also colored, resulting in similar coloration of surrounding objects. In 3D computer graphics, diffuse ...
White translucent photographic umbrella; a flash is shot inside the umbrella and the light is diffused onto the intended target; provides a soft, large light source. Sv: Sensitivity value. Sensitivity priority automatic exposure mode, where the photographer sets the ISO sensitivity and the AE firmware sets the aperture or shutter speed. TC
Soft light is light that tends to "wrap" around objects, projecting diffused shadows with soft edges, whereas hard light is more focused and produces harsher shadows. The hardness or softness of light depends mostly on three features of the source: the size of its surface, its distance from the object, and the thickness of its diffusion material.
A traditional umbrella-style reflector, used to diffuse light from a photographic lamp to which it is normally attached. In photography and cinematography, a reflector is an improvised or specialised reflective surface used to redirect light towards a given subject or scene.
A softbox is a type of photographic lighting modifier, one of a number of photographic soft light devices. All the various soft light types create even and diffused light [1] by transmitting light through some scattering material, or by reflecting light off a second surface to diffuse the light.
Diffuse reflection is typically characterized by omni-directional reflection angles. Most of the objects visible to the naked eye are identified via diffuse reflection. Another term commonly used for this type of reflection is "light scattering". Light scattering from the surfaces of objects is our primary mechanism of physical observation. [3] [4]
A common artificial lighting strategy that creates an overall appearance similar to natural fill places the fill light on the lens axis so that it will appear to cast few if any shadows from the point of view of the camera, which allows the key light that overlaps it to create the illusion of 3D in a 2D photo with the same single-source ...
