A portable folding reflector positioned to "bounce" sunlight onto a model. Reflectors vary enormously in size, colour, reflectivity and portability. In tabletop still life photography, small mirrors and card stock are used extensively, both to reduce lighting contrast and create highlights on reflective subjects such as glassware and jewelry.
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.
The rays represent luminous intensity, which varies according to Lambert's cosine law for an ideal diffuse reflector. Diffuse reflection is the reflection of light or other waves or particles from a surface such that a ray incident on the surface is scattered at many angles rather than at just one angle as in the case of specular reflection.
Softboxes, diffusers that cover the flash lamp, scatter direct light and reduce its harshness. Reflectors, including umbrellas, flat-white backgrounds, drapes and reflector cards are commonly used for this purpose (even with small hand-held flash units).
The sides and back of the box are lined with a bright surface – an aluminized fabric surface or an aluminum foil, to act as an efficient reflector. In some commercially available models the diffuser is removable to allow the light to be used alone as a floodlight or with an umbrella reflector.
This makes it a popular choice for various types of photography, including macro, portrait and fashion photography. Closely related to the ring flash is the continuous ring light, which can produce a consistent level of light for video recording or to see a live preview before capturing photographs.
In portrait photography, the beauty dish is used a lot more because of its ability to capture a more high quality version of the model's beauty. With the way the beauty dish creates certain shadows in the "portrait" of the model it basically sculpts the face of the model, so that their beauty is captured in a more unique and high-profile way.
