Borwin cross screen filter, also known as a star filter, creates a star pattern, in which lines radiate outward from bright objects. The star pattern is generated by a very fine diffraction grating embedded in the filter, or sometimes by the use of prisms in the filter. The number of stars varies by the construction of the filter, as does the number of points each star has. ldeal for photographing highly reflective surfaces such as water, glass or metal. Bright night city-scenes, festive lighting and sunlight on water are particually well suited for these filters. Available in all popular sizes.

Borwin ND filter allows the photographer to utilize a larger aperture that is at or below the diffraction limit, which varies depending on the size of the sensory medium (film or digital) and for many cameras, is between f/8 and f/11, with smaller sensory medium sizes needing larger sized apertures, and larger ones able to use smaller apertures.

Instead of reducing the aperture to limit light, the photographer can add a ND filter to limit light, and can then set the shutter speed according to the particular motion desired (blur of water movement, for example) and the aperture set as needed (small aperture for maximum sharpness or large aperture for narrow depth of field (subject in focus and background out of focus). Using a digital camera, the photographer can see the image right away, and can choose the best ND filter to use for the scene being captured by first knowing the best aperture to use for maximum sharpness desired. The shutter speed would be selected by finding the desired blur from subject movement. The camera would be set up for these in manual mode, and then the overall exposure then adjusted darker by adjusting either aperture or shutter speed, noting the number of stops needed to bring the exposure to that which is desired. That offset would then be the amount of stop needed in the ND filter to use for that scene.

Examples of this use include:

• Blurring water motion (e.g. waterfalls, rivers, oceans).
• Reducing depth of field in very bright light (e.g. daylight).
• When using a flash on a camera with a focal-plane shutter, exposure time is limited to the maximum speed -often 1/250th of a second, at best- at which the entire film or sensor is exposed to light at one instant. Without an ND filter this can result in the need to use f8 or higher.
• Using a wider aperture to stay below the diffraction limit.
• Reduce the visibility of moving objects
• Add motion blur to subjects

Borwin close-up filter is a simple secondary lens used to enable macro photography without requiring a specialised primary lens. They work identically to reading glasses, allowing any primary lens to focus more closely. Close-up lenses are usually specified by their optical power, the reciprocal of the focal length in meters. Several close-up lenses may be used in combination; the optical power of the combination is the sum of the optical powers of the component lenses; a set of lenses of +1, +2, and +4 diopters can be combined to provide a range from +1 to +7 in steps of 1. A split diopter has just a semicircular half of a close-up lens in a normal filter holder. It can be used to photograph a close object and a much more distant background, with everything in sharp focus; with any non-split lens the depth of field would be far too shallow.

UV filters - are used to reduce haziness created by ultraviolet light, to which photographic film and sensors are sensitive, but not the human eye. A UV filter passes all or most of the visual spectrum, and blocks ultraviolet radiation. (Most spectral manipulation filters are named for the radiation they pass; green and infrared filters pass their named colors, while a UV filter blocks UV.) It can be left on the lens for nearly all shots.

• If the lens is dropped, the filter may well suffer scratches or breakage instead of the front lens element.
• Filters can be cleaned frequently without damage to the lens surface or coatings; a filter scratched by cleaning is much less expensive to replace than a lens.
• If there is blowing sand the filter may protect the lens from abrasion from sand
• A few lenses, such as some of Canon's L series lenses, require the use of a filter to complete the weather sealing

Graduated neutral density filter -  is a neutral density filter with different attenuation at different points, typically clear in one half shading into a higher density in the other. It can be used, for example, to photograph a scene with part in deep shadow and part brightly lit, where otherwise either the shadows would have no detail or the highlights would be burnt out.

Circular Polarizer - allows you to remove unwanted reflections from non-metallic surfaces such as water, stone, glass etc. Light rays which are reflected by any surface can become polarized, so polarizing filters are used to select which light rays enter your camera lens. They also enhance colors to become more saturated and appear clearer with better contrast. This effect is often used to increase the contrast and saturation in blue skies and white clouds. Borwin polarizing filters do not affect the overall color balance of a shot.

Diffusion filter (also called a softening filter) softens subjects and generates a dreamy haze. This is most often used for portraits. It also has the effect of reducing contrast, and the filters are designed, labeled, sold, and used for that purpose too. There are many ways of accomplishing this effect, and thus filters from different manufacturers vary significantly. The two primary approaches are to use some form of grid or netting in the filter, or to use something which is transparent but not optically sharp.

Fast f/1.8 Compact FX-Format Prime (Fixed Focal Length) Lens

This updated classic with a fast maximum aperture is ideal for everyday shooting, perfect in low lighting situations and great for producing images with beautiful background blur (Bokeh). The AF-S NIKKOR 50mm f/1.8G includes Silent Wave Motor technology (SWM) for fast and precise autofocus, M/A Focus Mode Switch for seamless changes between manual and autofocus operation and an aspherical lens element for outstanding optical performance with high contrast.

Get Astonishing Low Light Results

This lightweight standard lens is a great travel companion because you never know when a beautiful, sunny day will turn cloudy and rainy. With its fast f/1.8 aperture, the AF-S NIKKOR 50mm f/1.8G will capture even low-light situations with stunning brilliance.

Achieve More Natural Depth of Field

Whether you're shooting portraits, food or nature-indoors or outdoors-the AF-S NIKKOR 50mm f/1.8G renders a beautiful, natural background blur (Bokeh) at its wider aperture settings. And its 50mm focal length is perfect for creating natural perspective in your photographs.

Shoot Tack-Sharp Portraits Every Time

Nikon's Super Integrated Coating (SIC) enhances light transmission efficiency and offers superior color consistency and reduced flare, while the AF-S NIKKOR 50mm f/1.8G's Aspherical Lens Element (AS) virtually eliminates coma and other types of aberrations, even when shooting at the widest available aperture. Pair that with Nikon's Silent Wave Motor (SWM) for fast, accurate and quiet autofocus, and you can be sure all of your portraits will be tack sharp.

Quiet Autofocus

A significant innovation in AF lens technology, Nikon's Silent Wave Motor uses ultrasonic (inaudible) vibrations-rather than a gear system-to focus the lens, providing incredibly smooth, silent and precise autofocus operation.

Quick Switching from AF to MF

When fine manual focusing is needed, simply rotate the lens focus ring-M/A mode allows you to seamlessly override the AF system with virtually no time lag.

Effective Aberration Correction

Since the 1960s, aspherical lenses have been an important part of the NIKKOR lens family. Virtually eliminating coma and other types of aberration, every new addition to the lineup provides a new level of contrast, resolution and compact design.

Reduce Lens Flare and Ghosting

Nikon's Super Integrated Coating enhances light transmission efficiency and offers superior color consistency and reduced lens flare.

A split diopter has just a semicircular half of a close-up lens in a normal filter holder. It can be used to photograph a close object and a much more distant background, with everything in sharp focus; with any non-split lens the depth of field would be far too shallow.

UV filters - are used to reduce haziness created by ultraviolet light, to which photographic film and sensors are sensitive, but not the human eye. A UV filter passes all or most of the visual spectrum, and blocks ultraviolet radiation. (Most spectral manipulation filters are named for the radiation they pass; green and infrared filters pass their named colors, while a UV filter blocks UV.) It can be left on the lens for nearly all shots.

• If the lens is dropped, the filter may well suffer scratches or breakage instead of the front lens element.
• Filters can be cleaned frequently without damage to the lens surface or coatings; a filter scratched by cleaning is much less expensive to replace than a lens.
• If there is blowing sand the filter may protect the lens from abrasion from sand
• A few lenses, such as some of Canon's L series lenses, require the use of a filter to complete the weather sealing

Graduated neutral density filter -  is a neutral density filter with different attenuation at different points, typically clear in one half shading into a higher density in the other. It can be used, for example, to photograph a scene with part in deep shadow and part brightly lit, where otherwise either the shadows would have no detail or the highlights would be burnt out.

Circular Polarizer - allows you to remove unwanted reflections from non-metallic surfaces such as water, stone, glass etc. Light rays which are reflected by any surface can become polarized, so polarizing filters are used to select which light rays enter your camera lens. They also enhance colors to become more saturated and appear clearer with better contrast. This effect is often used to increase the contrast and saturation in blue skies and white clouds. Borwin polarizing filters do not affect the overall color balance of a shot.

Diffusion filter (also called a softening filter) softens subjects and generates a dreamy haze. This is most often used for portraits. It also has the effect of reducing contrast, and the filters are designed, labeled, sold, and used for that purpose too. There are many ways of accomplishing this effect, and thus filters from different manufacturers vary significantly. The two primary approaches are to use some form of grid or netting in the filter, or to use something which is transparent but not optically sharp.
