Diffraction filters create a light pattern whose character will depend on the configurations applied to the glass line. Diffraction circle on the light filter can turn the light source in the frame in a solid, radiant glow spot or in a fireball that will depend on the distance between drawn lines and the diffraction ring around the light source will create a beautiful aura. If the diffraction pattern on the light filter is in the form of a cross, the rays coming from the light source on a photograph form a cross. Several concurrent lines will create a decorative effect snapshots ray beam. Similar figures for light filter may be a few, but to get the desired effect, you must visually combine the intersection of line marking with a source of light. Diffusion filters can serve as gauze, lace, nylon mesh, glass, oiled fatty substances. These filters, like washing out the light, create a feeling of light haze enveloping the objects, or dive sites in the fog. Perhaps a combination of one light filter phenomena of diffusion and diffraction.
For example, part of the filter surface can be lubricated fatty substances, why will the diffusion of light, and the clean sites may also be marked cruciform risk. Thus, part of an image on a photograph to be shrouded in mist, softening sharp transitions between light and shadow blurring the contours of objects, and diffractive cross contrastly oppose the diffusion fluctuation sharp bright rays resulting from the expansion of the luminous flux. Such compositions may send amazing state of nature, when shining sunlight pours in fresh and moist air. Variation effects, derived from the diffusion and diffraction of light filters, completely at the mercy of fantasy photographer. Compensation filters allow you to modify the tone, lighten or pritemnyat individual objects. Polarizing filter eliminates glare in snapshots, formed when light is reflected from smooth surfaces, creating a muted tone cut. Neutral gray filter on-location pritemnit bright color of the sky, and the color of vegetation makes it more saturated. Various methods of treatment, as negatives and positives in the laboratory, as well as special equipment and printing out pictures can be used as a means of expression. These include: solarization, , Threshold, monochromatic, obtaining a coarse-grained images, blurring the bas-relief, structural images, etc.
