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.
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. The best known form of reflective source is the umbrella light, where the light from the bulb is "bounced" off the inside of a metalized umbrella to create ...
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.
Diffuse interreflection is a process whereby light reflected from an object strikes other objects in the surrounding area, illuminating them. Diffuse interreflection specifically describes light reflected from objects which are not shiny or specular. In real life terms what this means is that light is reflected off non-shiny surfaces such as ...
Diffuse lighting (or diffuse reflection) is the direct illumination of an object by an even amount of light interacting with a light-scattering surface. [4] [12] After light strikes an object, it is reflected as a function of the surface properties of the object as well as the angle of incoming light. [12]
The resulting beam of light is wide and soft-edged, creating soft shadows, and is commonly used for back light, top light, and side light. Another method of controlling the spread of light is to use either a top hat (also referred to as a snoot), which generally limits the light coming out, or a barn door , whose flaps work as though they were ...
Pipkin's new frosted bulb revolutionized the industry, allowing the manufacture of frosted bulbs that diffused the light without losing much intensity, and were strong enough to be commercially viable. [13] [14] [15] He went on to make many innovations to the light bulb and two decades later developed the soft white light bulb. [20]
The key light can be "hard" (focused) or "soft" (), and depending on the desired setup can be placed at different angles relative to the subject.When part of the most common setup—three-point lighting—the key light is placed at a 30–60° angle (with the camera marking 0°).
