„All theory, dear friend, is grey, but the golden tree of life springs ever green“ writes Goethe in Faust. There is also a difference between the theory and practice of the grey values in photography. In the photographer’s day, not all filters are grey or, to put it better, neutral-grey. Grey is an „intermediate tone“ of the „achromatic“ colors white and black. In photography, neutral grey is used in different densities for contrast compensation or for reducing the light falling on the camera sensor. Lensinghouse filters are distinguished by their particularly high color neutrality. The Lensinghouse neutral density filters made of high-quality optical lenses, such as those used in lens construction, retain their neutral density even in extreme situations, such as in the case of lateral light incidence and also when shooting with wide-angle lenses, without the risk of color shading as can be observed with many filter systems. As the initiator of the Lensinghouse Filter, I am delighted to be able to present you with the Lensinghouse System a filter system that meets the highest quality requirements both in handling and in processing, but above all in its imaging performance. In theory and practice!“
Filters are used to reduce the amount of light required for photo and video recording as well as the realization of numerous special effects. Many image-enhancing measures and effects can be achieved digitally in post-processing. However, sometimes, some important filter effects can be realized better and simpler with high-quality optical filters. Subsequent digital optimization on the computer is reduced to a minimum.
Whether neutral density, graduaded neutral density or circular polarization filters – which type of filter is particularly suitable for which shooting situation, please see below under „Filter types“. To see some illustrative examples of the effects that can be achieved by the use of filters, please click on the following link.
Lensinghouse square filters are made of high-quality optical glasses and are optimally color-neutral. Both sides of the two millimeter thick filters are absolutely plane parallel so that the beam path of the recording system is affected as little as possible.
The filters are multiply anti-reflective coated on both sides. Those filter layers are applied using the latest nano technologies. Corresponding to the lotus effect, the filters are water and dirt repellent.
In contrast to screw-in filters, the square filters can be changed significantly faster. Unlike filters made of plastic, glass filters are also significantly more resistant to surface damage.
The glass filter series Lensinghouse Pro includes neutral density (ND), graduated neutral density (GND) and circular polarizing (CPL) filters in 100mm, 150mm and also in 180mm width. ND filters are available in different densities with shutter speeds of 2 to 15 stops. GND filters are available in the densities of 0.6 to 1.5 with a soft and partly also with a hard gradation as well as a reverse filter in the density 0.9.
The following pictures show examples of applications of the Lensinghouse Pro filters. Just click on a photo and move the line in the center of the screen to visualize the effect of the filter use.
The stable, aluminum-made Lensinghouse filter holders allow the fast, safe and precise positioning of rectangular filters in the front of the lens. In order to combine several filters with one another, the holders also have one or two additional slots, depending on the type of the filter holder.

Neutral density (ND) filters reduce the amount of light falling on the sensor. Thus, longer exposure times can be used or larger aperture apertures can be achieved with the same shutter speed. The Lensinghouse ND filters reduce the amount of light without affecting the colors.
Special effects that can be achieved by the use of ND filters are the blurred vision of objects moving during the exposure process, as well as zooming or dragging effects. Waterfalls or ocean waves are thus made into cotton-soaked structures and the impression of flowing movement is intensified. Also the use as a so-called ’street sweep‘ is very popular. This is where busy squares or busy motorways become free from people or cars due to a particularly long exposure.
Lensinghouse F-Stopper PRO ND filters include 100mm, 150mm and 180mm wide filters in different densities with extension factors of the shutter speeds of 2 to 15 stops.
While ND filters reduce the brightness over the entire image field, the graduated neutrality density (GND) filters darken the subject only partially. The colors in the covered picture parts appear more powerful, dramatic and more brilliant. Contrasts are balanced, but can also be amplified or weakened.
GND filters are permeable until about in the half of the filter the gradation begins, which is either soft or hard. By moving the filter, it is possible to precisely determine from which point in the subject the exposure should be continuous or abruptly darker.
Filters with a hard profile are preferably used with telephoto lenses, since the transition is „softened“ due to the low depth of sharpness. However, filters with a soft gradation are used for wide angle lenses. The transition is hardly influenced by the large depth of sharpness.
The so-called reverse filters are a special form of the GND filters. With this filter type, the strongest coloration is in the center of the image, on the horizon. The coloration weakens upwards and downwards. Reverse filters are mainly used when light streaks are in the subject, such as at sunrise and sunset.
The Lensinghouse filter system includes 100mm, 150mm and 180mm wide GND filters in the densities 0.6 and 0.9 with hard or soft gradation as well as reverse filter in density 0.9. In addition, GND filters with a soft profile in 100mm and 150mm width are also available in density 1.2 and 1.5.
> Detailed information on the use of graduated neutral density filters can be found here in the FINEARTPRINTER workshop (only in German).
Circular polarizing filters are used to penetrate the vapor of atmospheric disturbances as well as to reduce or completely eliminate reflections on non-metallic surfaces such as water or glass surfaces. In this way, colors become clearer, stronger and richer in contrast. Windows and water surfaces become transparent. The strength of the filter effect depends on the filter position and can be controlled almost continuously by filter rotation.
The Lensinghouse filter system offers circular polarizing filters in 100mm, 150mm and 180mm width.

The Lensinghouse filter holder II takes filters of 100mm width. It is equipped with a quick-release device for adapter rings, with which the filter holder can be adapted to lenses of different front threads. Adapter rings with thread diameters from 58 to 82mm are available.
The filter holder has three slots into which the filters can be precisely positioned and secured by a special spring clamp.
The Lensinghouse filter holder II also accepts 100mm wide filters of the brands Lee, B & W, Formatt HiTech or Cokin Z-Pro. Optimal results without disturbing vignetting or lateral scattered light are mainly achieved by the use of Lensinghouse glass filters as the system is adapted to this.
For certain wide angle lenses without front thread, specially adapted filter holders have been developed, which fit directly onto the permanently installed lens hoods of the respective lens. Currently available are Lensinghouse filter holders for the following lenses:
– Canon TS-E 17 mm
– Nikkor AF-S 14-24 mm
– Tamron SP 15-30 mm
Since each solution is a custom-made solution, no adapter rings are necessary. Depending on the type, two or three filters can be installed simultaneously. In order to avoid edge shading in the wide-angle range, relatively large filters of 150 mm width must be used.n.
The Lensinghouse filter holder specially developed for the Canon EF 11-24 mm fits directly onto the permanently installed lens hood lens of the lens. Since this solution is custom-made, no adapter ring is required. The filter holder is equipped with two slots so that two filters can be installed simultaneously. In order to avoid edge shading in the wide angle range, a filter of 180mm width must be used.
Radomir Jakubowski is a graduate in business administration and an independent photographer. He has been a GDT full-member for many years, co-founder of the GDT Youth Group, and today GDT’s board member. His great passion is nature photography. At the age of eleven he was confronted with photography for the first time. To date, his recordings have been published in numerous specialist magazines, books, postcards, calendars and national as well as international competitions all over the world. 2013, Rheinwerk Verlag published his first book „The photography school in pictures: Natural Photography“ in collaboration with Sandra Bartocha and Werner Bollmann.
Rare and spectacular motifs are not absolutely necessary for him, but rather he enjoys the shapes, lines and colors of nature. Today, he covers the wide spectrum from close-up to animal and landscape photography. He always tries to creatively represent the motifs, in order to give each painting its own note. His photos are not created by composing on the PC, but on-site.
And this is exactly why Radomir likes to work with Lensinghouse filters. He says, „Why am I supposed to merge several pictures and work at home on a PC to capture the dynamics of a landscape if I can achieve this by using GND filters? I like to use high-quality ND, GND and polarization filters. I am concerned about the color neutrality and visual clarity when using filters. It is especially important to me that the filters do not create additional color shades in my pictures. Each additional element, which is screwed in front of a lens, affects the image quality. I spend a lot of money on the latest camera housings and the best lenses. I also expect perfection from the filters used, whether it’s the quality, the colors or the processing, and that is exactly why I work with Lensinghouse products. They are, in my opinion, the best on the market. “
Probably in the mysticism of the father’s darkroom, Jürgen Waffenschmidt, who was 16 years old at that time, developed his chronic passion for photography. But only after the death of the father did he take his time for photography, with almost infinite endurance and tireless commitment. He learned the technical handicraft autodidactically. Together with his feeling for the one motif, his very own photographic handwriting now bears fruit: Jürgen Waffenschmidt’s photos and videos find a growing recognition in the international photo scene. The peculiarities of his photos are: they reflect the magic of the landscape and nature as the photographer sees them. The light is often used as an „assistant“ to him. In doing so, he uses the original RAW file as a negative, in which only the most essential is optimized during development.
„I’m trying to photograph the subject so that post-processing is kept to a minimum,“ he says. The Lensinghouse filter system helps him in a variety of ways. The photographer regularly uses all filter types of the Lensinghouse filter system, especially when shooting water, such as lakes, rivers or the sea.
„I use them all: ND, GND and circular polarization filters,“ he says. „ND filters to achieve motion effects while exploiting long exposure times; GND filters to work out contrasts and to bring drama into the motif and the CPL filter to make structures visible. But also to eliminate mirroring in windows, for example, and to make the colors appear stronger. „In addition, GND filters are used in their increasingly occupying video recordings.
The nature and travel photographer does no longer use screw-in filters. „They’re too cumbersome for me. Motif changes, re-focusing, test exposures are much faster and easier with a filter system like Lensinghouse. With that system I have everything from one hand, for all occasions and in high quality. I only need a highly tempered glass. Spacer rings are available for all lens threads, „he justifies his choice.
Not that the nature and travel photographer Uwe Statz looks at the world throuhg pink-tinted glasses, but in any case with different eyes than many of his colleagues. This is also the secret of his extraordinary pictures that are due to many fine tools that are screwed in front of the lenses and which accompany him on his way through nature – all from the Lensinghouse high-end filter system.
When Uwe Statz takes a picture of the world, he places great value on the fact that everything appears in the right light. For him, the perfectly captured light is the crucial factor for a successful photo. One of the most important tools on the way to the perfect image is the Lensinghouse filter system.
Often the viewer does not notice the use of filters until the second or third view, when he asks why the clouds float above the landscape like tattered, fluffy feathers, or why the mighty floods of the waterfall fall supersoftly to the valley. „Such long-term exposures evoke an aesthetic in the motif, which I as a person in reality can not perceive,“ explains Uwe Statz. „That makes those recordings interesting for the viewer. Waterfalls become wavering fogs that do not exist in reality. “
Uwe Statz has a particular preference for the F-Stopper Pro ND filters and the circular polarizing filter from Lensinghouse. „They have inspired me from the start through their absolute color neutrality,“ he fancies. But the simple and fast handling has also contributed to this. „If you are standing on a cliff with the spray of surf waves all around you, then a necessary filter change, an adjustment or even the cleaning must go very fast.“
Like many well-known nature photographers, Ive Völker operates the photography on a part-time basis. But this with persistent passion. He photographs since he was 12 years old. At 14, he bought his first DSLR camera and from 18 onwards the equipment was expanded continuously. In photography, he sees the ideal tool to realize his pictorial ideas, which he plans carefully. As he is basically working in the RAW format, he considers optimizations in post-processing as essential. Nevertheless, there are influences on the image statement which, in his opinion, can only be realized with optical filters and directly on-site. The few filter types that he considers absolutely necessary are ND filters as well as polarization filters.
In search of the perfect equipment, the young photographer had the opportunity to test the Lensinghouse filter system. He summarizes his judgment as follows: „The color quality, handling and processing of the Lensinghouse filter system meet the highest demands and leave nothing to be desired. However, quality also has its price. “
