As compared with a film SLR camera, a digital SLR has some different functionality. As film SLR cameras require a film to expose a photograph, they require precise and accurate manual adjustment for lighting such as camera aperture and shutter speed settings, along with a good built-in or external light meter to gain mastery. It can take a long time to get to grips with the properties of different types of film (such as colour and back and white print and slide films, panchromatic, along with specialist films like ones sensitive to infra-red light). DSLRs are very easy to operate, as they are generally more recent and have more technology built in. Although the fundamentals of good exposure and composition are the same as in film, there are usually more automated settings and, most importantly, an in-built LCD window which shows the immediate result of your shot.
Camera filters are a traditional tool used in photography to enhance or add an effect to a photo, although digital photography is much more advanced & many filter effects can be created via computer applications. There is still a huge number of experienced photographers, many who have used film, who know that digital effects applied post-exposure are no substitute for natural beauty. In addition, the feeling of creativity cannot be obtained by applying techniques without knowing their origin, effect nor without mastering light & exposure.
There are numerous camera filters which can also be used with digital photography. Few of them are named below.
Close-up filters:
The subject or object can be optimized up to one time more as compared to original, with magnification power of close up lens +1 it helps you to capture the details of jewellery, flowers and enlarge the particular portion from group photograph.
With magnification power of close up lens +2, one can enhance a detail up to two times greater then the actual image. +2 lens helps you to capture the details of jewellery, flowers and enlarge the particular portion from group photograph.
Four times greater image can be obtained with the use of close up lens +4. With magnification power of close up lens +4 , you can capture the tiny details that could not be possible using a bare lens. Close up lens +4 is also useful in product photography .
Close up Macro Depending Upon diopter Close Up Lenses help you go closer to a subject and to enlarge a particular portion from a group photograph and to capture details of finger prints, inspects, flowers.
******Either close up lenses or a Macro lens kit work best with a standard lens system. A digital camera works on a chip based motherboard, which is a computerized system and sometimes fails to recognize close up lenses in auto mode. It is recommended to use close up lenses in manual focus mode to set your own way to photograph a tiny object.
A close up photograph optically optimized can also further digitally optimized.
Soft-focus Camera Filter is used to take a crispy sharp-focused center portion which is surrounded by imaginative, dreamy, multicolored & balloon studded environment does not exist in actual. Using a soft-focus filter is very easy, you may use spacer ring for better result.
The grid structure of a Star filter 8X creates eye-catching 8 point star like patterns from brilliant points of light. The brighter the light source in the scene the greater the light scattering effect will be. A dark background & use of spacer ring is recommended with lens filter star 8x.
A photographic filter made of colored glass that modifies the light striking the film or digital sensor by selectively absorbing colors. The blue filter is used to create the yellow negative, in black & white photography while also used in digital color photography just to add fun colors in a scene.
Multi-image lens – made up of fine optical quality glass lens filter blank. This Multi Image lens creates 5 identical images in radial pattern of the subject to the same picture frame. lens filter Multi-Images comes in more then 35 patterns.Dark background & use of spacer ring is recommended.
Star filter 4x has a special grid section that creates an eye-catching 4 point star like patterns from brilliant points of light. The brighter the light source in the scene sharper the light scattering effect will be. Dark background & use of spacer ring is recommended to use lens filter star filter 4x filter.
Lens filter sand is a very popular camera filter with a clear polished spot at the center, so a sharp image is obtained in the center of the picture, surrounded by diffused or smoky screen. You may use spacer ring for a better result.
Lens filter D1 Diffuser diffuse highlights reduce contrast and as such can be used for taking pictures with variable soft effects. A diffuser filter is a translucent photographic filter used for a special effect, softens subjects and generates a dreamy haze.
As the Diffuser D2 filter softened the skin – texture, the portraits of ladies can be made very charming & attractive. Widely used in fashion photography. A diffuser filter is very inexpensive simply place it over the lens and see for yourself the difference.
The diffusion effect is minimum with “Diffuser”, stronger with “softone”, followed by “Duto” and strongest with “special softon”. A Duto lens filter reduces the contrast to produce good result by creating softened images due to its irregular, uneven surface.
Dreamy landscape pictures can also be shot without suppressing details in the photo. It can be used particularly in commercial photography and effect is strongest with lens filter special softon.
The Fld filter corrects true-to-life color rendition by removing the harsh yellow-green cast ordinarily resulting from fluorescent bulbs, can also be used in outdoor for saturating colors. DSLRs should not really need this for colour correction purposes, as it will be handled by the manual or auto-white balance feature.
A photographic filter made of colored glass that modifies the light striking the film by selectively absorbing colors. A green-coloured filter transmits a narrow wavelength of light in the green spectrum and absorb blue and red light.
A yellow filter makes b/w photos look just about natural. For example a yellow filter will enhance the contrast between clouds and sky by darkening the latter.
Orange filters will darken a blue sky more than a yellow filter, and this is often why they are used. However remember that an orange filter will also lighten orange values. The rule for colored filters is that they darken their complementary colors and lighten their own color.
Polariser (or LPL) filter eliminates undesired reflection from non – metallic surfaces such as window glass, water, etc, It has Sky brightness control, eliminating veil caused by atmospheric haze, Blue Sky etc. It can be used with any digital camera.
This Multi Image lens creates identical image of 3 in Triangular patterns of the subject to the same picture frame.Multi-Images comes in more then 35 patterns. Use of spacer ring & dark background is recommended to achieve best result.
Ultra-violet (UV) filter is a screw-in type which protects the camera lens from direct exposure of dust, humidity moisture and thus increasing lens life and its original quality remains intact for a prolonged uses. It can also reduce the visual haze we see on sunny days.
Sepia filter produces brown tone for sepia. The use of this filter gives a surrealistic effect in landscape and architectural photography by producing “storm like cloud” effect, “Moon light” effect, “Wood effect”.
The two field lens is used for that special shot where two subjects one “distant” and the other “closer” both need sharp focusing within the same picture frame.
Veri-cross Filter Star Filters creates 6 point eye-catching star like patterns from brilliant points of light. The brighter the light source in the scene the greater the light scattering effect will be.
The above-mentioned camera filters are the most popular type & easy to use. There is no technical qualification is required to use above camera filters. These are screw in type camera filters available in different camera lens filter threads. Most popular camera lens filter threads are
20mm, 24mm, 25mm, 28mm, 30mm, 37mm, 40.5mm, 43mm, 46mm, 49mm, 52mm, 55mm, 58mm, 62mm, 67mm, 72mm, 77mm, 86mm, 95mm, 105mm, 110mm, 127mm.
Lens filters are usually made up of optical glass, multi-coated camera filters claim to filter unwanted reflections while taking a snap, however with the use of lens hood unwanted reflections can be prevented & it is always a good practice to use a lens hood.
Multi-coated camera filters require more care and are often much costlier as compared with non-coated filters. A single scratch will ruin the quality of multi coated camera filters.
The image quality is slightly better with the use of coated filters while, where cost is a real factor, it is always recommended to use a non coated camera filters as it is cheaper & durable as compare to coated camera filter.
It is also possible to use filter mounting systems. Instead of screwing a circular filter into the filter thread of the lens, you use a filter holder instead, into which square filters can then be placed. If you have more than one lens, the filter thread sizes may differ and a filter system can save the expense (and weight) of having to buy, say, 2 yellow filters. Popular brands are by Cokin and Lee.
