Black and white imaging records only tonal differences between colored objects, which appear as black, white, or different shades of gray. Proper rendition depends on your own desires, and, for film, the differences between film sensitivity to colors and that of the eye. The latter is due to the fact that most panchromatic emulsions used are more sensitive to blue, violet and ultraviolet than to other colors. Therefore, blue appears as lighter on film than it does to the eye. This can make a blue-sky light enough to appear a similar shade of light gray as the clouds that are in it, making the clouds "disappear."A more "correct" cloud presence is obtained through the use of a yellow filter, such as a Yellow 8, which can absorb blue light, darkening the sky to more closely match what the eye would see. The Yellow 8 also acts as a general compensator for most subjects, giving a tonal rendition similar to that of the eye.

The Zeikos 52mm Universal Professional Tulip Lens Hood is primarily designed to prevent unwanted stray light (flare) from entering the lens by extending and shading the end of the lens. In addition, since the end of the lens is extended, you also get the added benefit of some extra protection from accidental impact. Screw-mount lens hoods, such as this 52mm, are designed to screw right into your lens or filter. Rear locking ring allows the user to rotate the hood in 360°direction.
This 5-piece cleaning kit contains everything you'll ever need to properly clean your lenses, including a Lens Cleaning Tissues, Lens Cloth, Lens Cleaning Liquid, Brush and Cotton Swabs.

The robust lens hoods of the DV series are specifically designed for the permanent use on digital video cameras, to protect the exposed and sensitive lenses of video cameras from mechanical damage. The angles of these rectangular hoods match with the shooting angles of digital video cameras. DV series lens hoods are also provided with an additional protective cap, which can be put on front of the hood. The main function of the lens hood is to shade the lens from stray light, improving your contrast and image quality. But it will also protects the front barrel from the inevitable impacts against walls, door frames, and other real-life obstacles and in inclement weather, it can assist in keeping moisture or wind-blown debris off the lens. This hood enables you to shoot even towards the light source (in bright sunlight) without excessive flare, as long as you keep the light source outside the image area. Installation: * Screw an UV-filter (or any other filter) either directly on the front of the lens or on the adapter. * Attach the lens hood on top of the UV-filter with the symbol at 12 o'clock. * Fixate the hood using the lock-screw of the hood.

Neutral Density filters have several uses and offer the possibility to achieve otherwise unachievable results. ND filters appear gray and reduce the amount of light reaching the film, they have no affect on color balance. The main uses of Neutral Density filter are: To decrease depth of field by allowing wider apertures to be used, which helps separate subjects from their background. To enable slow shutter speeds to be used, especially with fast films, to record movement in subjects such as waterfalls, clouds, cars, seas etc. To decrease the effective ISO of high speed film (ie: above ISO400) and allow it to be used outdoors in bright situations. To allow video cameras (which have fixed shutter speeds) to film subjects such as snow, sand or other bright scenes which would normally cause over-exposure.
