Filters - Diffussion
|
Generally, diffusion filters fall into one of three main categories: 1. Image softening filters. These are filters that primarily affect resolution. These filters act cosmetically to hide wrinkles and blend blemishes on the actors. 2. Black fogging filters. These are low cons and other filters that raise the exposure of black levels. 3. White or highlight-flaring filters. These filters flare or put a "halo" around "blown windows," light sources, or areas of high exposure. They can also be used to reduce picture contrast by lowering white exposure, and to create romantic or "period" looks. These are the three main types, but some diffusion filters fall into more than one of these categories. Combination effects can be achieved by combining filters, or by choosing a combination filter that is designed to provide the effects of more than one primary filter-type. Black Frost These filters flare highlights, mute colors, and tone down contrast, while retaining rich blacks. This is a very useful combination of effects for 16mm and 35mm film, as well as for HD and standard video. These are primarily styling, or mood modifying filters. Depending on the grade chosen, they subtly enhance a scene without degrading the image quality or black saturation. Black Frost enables cinematographers to capture blacker blacks than are possible with similar types of filters. Black Frost filters are made using a remarkable, new diffusion technology, to achieve a unique image styling that can be applied freely, without fear of having scenes appear "heavy-handed." Black Frost filters contain thousands of MicroPore™ particles, which introduce precise amounts of light diffraction while controlling stray light and flare. They are the result of proprietary Schneider design and manufacturing techniques that refine and calibrate the embedded diffusion particles in ways that have not been used before in filter manufacturing. Black Frost filters provide an array of precisely sized particles that control the degree of diffusion in a predictable and repeatable manner. By solving the problems of excessive light scatter and veiling glare associated with similar filters, Schneider Black Frost filters make possible a higher level of control and convenience.
White Frost® Schneider White Frost filters are primarily picture styling, or mood modifying tools. They subtly "flare" highlights and very slightly tone down contrast, while having no effect on image resolution or color reproduction. These filters are very useful for adding a "halo" around light sources, "blown windows," or any other area of high exposure. They can also be used to reduce picture contrast by lowering white exposure, and can help you create a romantic or "period" look. Schneider White Frost filters provide a very useful combination of effects for 16mm and 35mm film, as well as for HD and standard video. Depending on the strength chosen, they enhance a scene, subtly or strongly, without reducing image resolution. If you prefer a softened, romantic image, a White Frost filter can be combined with a Schneider Classic Soft filter. Pro-Mist® Most popular motion picture effect. Creates special "atmosphere" by softening excess sharpness and contrast; creates pearlescent glow around highlights. Great for portraits and landscapes. Available in several grades.
Less lightening of shadows and reduction of contrast. Black Diffusion/FX™ & Gold Diffusion/FX™ Filters The Black Diffusion/FX and Gold Diffusion/FX filters use a unique optical construction that produces the most advanced diffuser ever developed by Tiffen. They create a diffused image that doesn't look like it's been shot through a filter. The BLACK DIFFUSION/FX filter gives a silky-smooth look to textured surfaces. So it does a spectacular job of suppressing facial blemishes and wrinkles, while maintaining a clear, focused image. The young woman's eyes and the jewelry twined on her wrist stay crystal clear, while her face loses the "edginess" of the unfiltered shot. The effect is flattering, by virtually eliminating unwanted details, but without being dull or "fuzzy." At the same time, a bare minimum of highlight flare is produced. The effect of the lighter grades is subtle, with the higher grades becoming gradually more noticeable, all capable of providing a beautiful image.
The GOLD DIFFUSION/FX filter takes the effect of the Black Diffusion/FX a step further. It adds a soft, golden tint to shadows, and infuses images with a special warmth. et it still manages to balance any mix of skintones. Neutral colors appear minimally affected, while cool colors and skintones are slightly warmed and softened with beautiful results. The veiled woman takes on a more mysterious, yet inviting, air. At the same time, her eyes and the intricate design of the veil stay clear and sharp. As grades increase, so does the diffusion, but the warm, golden tint stays constant.
Identical to the "old" Mitchell Diffusion glass, the Mitchell diffusion filter is the result of Pancro's patented diffusion process upon a single-piece of optical-select glass. If is available in softness variations of A, B, C, D, and E and all standard sizes. There are two kinds of Mitchell Diffusion Filters: (1) "Overall" Diffusion and (2) "Split" Diffusion. In "Overall diffusion, the degree of softness remains the same from edge to edge. In "Split" Diffusion degrees of softness may be varied to any two combinations. For example, if filming an older leading actor opposite a younger actor in the same frame, a "Split" Diffusion Filter of B-to-Clear may be used--the B side for the former and the clear side for the latter. For many years in the movie industry, the Mitchell Diffusion Filter has been used for close-ups to flatter and soften facial imperfections. This includes softening undesirable features such as freckles, blemishes, and wrinkles. It is also used to create a romantic ambiance by softening colors and cutting sharpness. In operation, the Mitchell Diffusion Filter softens an image by refracting a portion of light as if it passes through the lens. Whether softening facial features and colors, or cutting sharpness, the resulting effect on screen is always subtle and unobtrusive. Black Dot Texture Screen The Harrison Black Dot Texture Screens enable you to have all the good effects of diffusion without having a whitish veil over the entire scene or unwanted halos around light sources. The Black Dot Texture Screens refract light in the same manner as the regular diffusions, but there the resemblance ends. Because of the black dots within each filter a light loss of about one stop must be compensated for in shooting. The texture screens are manufactured in SETS ONLY, consisting of five filters. If your requirements call for the general softening of a scene, breaking the edges of images, the spreading of defects over larger areas, and brilliant colors rather than a whitish veil, then the new Black Dot Texture Screens are the ONLY tool capable of achieving this type of finished picture for you. |
