Durst history... and advanced photographic equipment

“Dirset” is a name heavily present in the world of photographic equipment, and it is a name taken from the family of young designers who set their sights on providing advanced photographic equipment.
Here is an overview of the history of Durst, with a review of its most important equipment.

Photographic equipment was the most important concern of the two young design engineers, Julius and Gilbert Durst, and so the brothers diligently worked with enthusiasm and made a little bit of these machines, which for years had been working in a manner that provided complete satisfaction to their owners. However, obtaining other licenses for photographic equipment developed by them required more capital. For this reason, the Durst brothers turned to Louis and Heinz Oberuch in search of financial support. The Oberuch brothers agreed to provide assistance, as only a short period of time passed from working together. They were then convinced of the extraordinary technical talents of the Durst brothers.
This led to a decision to put production on industrial bases and to establish a joint-stock company that started its production activity in a modest factory. It is the home of the Durst brothers.
Durst AG • had a very quiet and humble beginning. Since its inception, great importance has been given to the most practical requirements of each of the individual contents, while adopting as much precision as possible in each manufacturing process.
From here, it only took a few years for the name of Durst to become well-known in the field, and even for Durst's photographic trade products in Italy, even outside the Italian borders before the last world war.
This production programs include enlargement and copying equipment for all photographic fields: amateur models
And professionals for industrial photography as well as for engraving arts, in addition to producing holders for magnifiers, lamps for dark rooms, and more useful laboratory parts and accessories. Hedrist products are exported to more than 120 countries.
Where the new factory is located with all its technical departments in Brixson, while the commercial department of the company is located in neighboring Posen. There is also a branch in Germany working to raise sales in that important market.

As for the reason behind the company's success? ..
Let's start by saying that Durst eliminated the old-fashioned design in the field of making magnifiers and brought completely new manufacturing standards to the photographic equipment sector that had previously been severely neglected.
And Durst also maintained the development of magnifiers at the same rate as the imaging rate that accompanied the camera industry, as their magnifiers not only look modern like those cameras, but also allow for more improvements to today's cameras in the dark room. That is because the possibilities of using new materials and modern production methods, such as alloys - metal by pressure. They give freedom to correction methods to blend the aesthetic element with economical accuracy and perfect practice.

This, it should be noted, is the new industrial land. Durst occupies an area of ​​45,000 square meters, while the actual floor area occupied by the factory is 15,000 square meters. The latest construction standards for industrial centers have been applied so that the factory turns into a stunning example of aesthetic industrial construction.

It should be noted that technical developments are constantly taking place on Durset products, which means that the details of the specifications of the devices that we will review here are entirely subject to modification from time to time.

- Dearest M 707 Color

A pioneering product in everything with great engineering.
This new cycle amplifier was designed by - Durst. To meet the advanced needs of those who love to work in a home darkroom with many possibilities, the result is that solid engineering and exquisite manufacturing secure that sense of confidence that accompanies perfection in color zoom. What is meant by Durest (M 707 Color) is the photographic technician that can instinctively correct simple color intensity and tinge without relying on electronic aids to filter position measurements and exposure measurements - and accurately corrects 40 x 50 cm or 16 x 20 inches without any problems.

This enlarger, equipped to work on film scales from disc to 6x7cm, has interchangeable inline mix boxes and film scale inline conversion boxes intended for typical professional illumination with full diffusion illumination.

- The main advantages of Durst, M 707 Color

This magnifier accommodates all sizes of film from disc to pocket number 110 and from 35 mm to 6 x 6 cm and 6 x 7 cm. Standard equipment for 24 x 36 mm films includes a great quality universal holder for negatives with 35 mm mask inserts, and a 12 tungsten-halogen lamp. 100 watts voltmeter, adapter and lens plate suitable for film scale with focal lengths from 35 mm to 105 mm.

- True magnifier, with equal color mixing and equal lighting:
Experience highlights its most prominent meanings in the unique way that the magnifier adopts to face all the dilemmas that arise in all areas of professional use. For this reason, the high-quality color mixing head does not contain intense lighting, and to obtain great detail in the magnifications, the color mixing head contains a set of two-color filters and a very effective white light lift, and the luminance is diffused correctly, blurs scratches and dust, ensuring a good color mixture of up to 170 . As for the standard model - 35 mm - and its conversion packages of 6 x 6 and 6 x 7 cm, it focuses the light on the negative scale with the used movable implicit mixing boxes, which allows for shorter exposure times and achieves maximum benefit from the strong tungsten halogen light, illuminating the image evenly, even to the corners. This is because the advanced design eliminates the dilemmas of stray light and film fatigue, and then comes the reflection system to reduce the heat in the negative surface to a minimum.

- Finest quality metal film stand, hinged inline masking tapes, interchangeable masking baffle structures, recording class pins and adjustable film stops are some of the details of this professional exemplary.
Display on the floor and the wall and full control of distortions, Scheimpflug type.
The long solid side column allows enlargements of up to 40 x 50 cm or 16 x 20 inches on the base plate, but we can swing the head for display on the wall or on the ground to achieve larger prints. This is also because by tilting the head and lens of the magnifier, you get a complete adjustment of the converging verticals.

- Wall mount accessory
In a dark and permanent room at home, we can install the magnifier on the wall to make it more stable, and this also facilitates making giant enlargements.

Exceptional accuracy
The metal structure and precision manufacturing keep the negative metal structure lead, the lens and the viewing surfaces parallel in every sense of the word, in order to achieve a perfect and comprehensive protrusion sharpness. And Karnak. In addition to the precise focusing by friction drive, it makes the work really easy, while the special mind keeps the unit looking new, even after using it for years⏹
