Konstrastumfangs

Bring more dynamics in your photos every owner of a camera, whether it is an analog or a digital camera, knows the problem of the limitation of the available Konstrastumfangs the recording technique. On countless photos a blue sky is much too bright, the clouds are usually completely disappeared or just dull recognizable and the people under the trees are only a shadow of itself. Motives were always just been a special challenge for the photographer with high contrast ratio. In the peak of analog photography, ambitious hobby photographers had mostly grey filter in the luggage to darken the sky in very intense sunlight. The use of Flash to the lightening of the persons or objects in the shady areas was almost a standard procedure. A common method to adjust the contrast scale to the real situation was in the times, as they even developed the shots, at least Dodge or burn parts of the image during development in the darkroom. After all, a dynamic range of 18-19 occur in nature with intense sunlight and ideal conditions f-stops, which corresponds to a dynamic range of approximately 2,000,000: 1.

Although this contrast of our eye cannot easily at a glance to process, so but the human eye can capture quite 14 exposure units, about 15,000: 1, with a quick glance. Now given itself a modern digital camera can handle 10 f-stops, itself only under ideal conditions and using the RAW format is possible, you can see quickly the limits of recording technology available today. To the availability of affordable cameras that take at least the contrast range the human eye can perceive, it will take probably a few more years. The current solution to the problem lies in an intelligent post-processing of the images and a corresponding adjustment of the recording procedure. The simple-sounding but effective approach is that when the recording not only an image with an exposure setting makes, but takes an exposure series with different aperture and shutter settings. A good compromise is already taking 3 images, where these are carried with the aperture setting plus the underexposure (minus 2 f-stops) and overexposure (plus 2 f-stops), proposed by the camera.

Creating rows of 5 or more shots can still significantly improve the contrast expansion, however, the majority of today’s digital cameras allow only the automatic creation of up to 3 shots. A look into the manual of your camera is usually necessary for this. There are now a variety of HDR – software programs, which then generate a so-called HDR image on the computer from these 3 or more shots of the part, which has a much higher dynamic range than each individual shot. Because most output media, such as the monitor of a PC or an inkjet printer, can not directly represent usually these high contrast range, yet the tone-mapping joins the HDR process, what one of the HDR software packages that have been mentioned and a little dexterity is needed. Of course, there is the HDR photography to consider many things before a masterpiece can arise, such as the correct settings on the camera, using a tripod with long exposure times and of course the right choice of HDR software that exists as both a free and professional purchase variants. To the more intensive preoccupation with the HDR photography, there are very good books and also articles on sites on the Internet. It is worth in any case to venture once their own experiments as successful HDR photos are true eye-catchers on each presentation or photo albums. Jurgen Gobel.

German Cars

Germany’s favorite child is the car. What goal must be achieved, but these days, and conveniently take the cars. Actually, the mobile frame on four wheels, not only in Germany is so popular, but worldwide. Currently there are about 800 million cars around the world, all others still do not like Vehicle motorcycles, trucks and buses included. Apart from the fact that this continuous growth also brings environmental issues to face, to the driver and car hobbyists, many other problems: “Where can I get spare parts here for it?” – “What are the workshops are available in my area?” – “Offer which companies for my car to a tuning? “,” Where do I find interesting car clubs? “and much more …

The car cars Directory Links here has created the opportunity to create all sorts of industries and fields of an archive for companies, addresses and contact persons. Everything is about cars, cars, car tuning and technology here be accommodated, or found. The database will grow steadily with its further existence. A topic-specific Web catalog (no matter what subject) raises, in principle, on the quality of the general engines, have placed the same things about somewhere in a deeply nested sub-category. In addition, the links to the websites do not lose too much important as simply do not arise countless category levels, which is why the webmasters about their sites have more of it.

But the most offensive is that laptop manufacturers to stop supporting Windows xp, Windows Vista and cease to lay out a driver on Windows xp. One such case occurred to me – a brand new hp Pavilion 6500t was brought to me, my brother from America as a gift. I liked the laptop, but it is installed on os Vista Home Premium I did not like, although the hardware filling pretty good – cpu Intel Duo Core 2 T7300 2Hz, 2 gb ram, 160 gb hdd, vista vseravno gives a sense of some nespshenoy os. In general, the decision was made – to reinstall the operating system and put Windows xp. As it turned immediately had problems – one of them, the bios simply does not switching function of the sata hard drive in compatibility mode, and therefore to install WIndows xp drivers required.

Fiberglass Reinforcement

Fiberglass EQUIPMENT FOR CONCRETE "Reinforcement Polymer Composite (ARC)" TU 2296-001-3965478-2006 Fiberglass reinforcement (SPA) is an increasingly strong position in modern construction. This is due, on the one hand, it high specific strength (ratio of strength to specific weight), on the other hand, high corrosion resistance, frost resistance, low thermal conductivity. Spa construction with non-conducting, which is very important occurrence of stray currents and electro-osmosis. Without hesitation Peter Asaro explained all about the problem. The basic design principles of reinforced concrete structures applied to concrete elements of the spa. On the strength of the SNA is not inferior to steel reinforcement, however, due to more high cost is mainly used in important structures, which are special requirements. These structures include, in particular offshore structures, especially those parts which are in the zone of variable water level. Corrosion of concrete in sea water salinity of the ocean varies in small range and is 34-35 g / liter.

PW value is usually equal to 7,8-8,3. Atlantic Ocean, for example, contains about 11 g + 1a, 20 g of C1-, 2.9 g $ 042 – and 1.4 g of M2 + per liter, as well as smaller quantities of K +, Ca2 +, W-, HCO-(0.08 g / l). SNIP 2.03.11-85 will assess the degree of aggressiveness of the water environment (including sea water) for eight types of corrosion, listed in Table. 1. Table 1.
