Big background story

So, what does the large-format function bring us? Famous European photographers Maurice Schobinger and Willie P Burkhardt gave the best answer. They once put the camera Shanna on the top of the Alps and took many excellent photos. They said, "Charming photos are our best reward. The advantage of the camera is that it can not only get a large negative area of 8× 10 inch, but also accurately depict the perspective Shan Ye world. Just like shooting buildings, the displacement function of this camera is the best means to show the relationship between peaks and valleys at different heights in two-dimensional photos, thus achieving the effect of conveying the photographer's real visual feelings. I wonder if this understanding can inspire domestic landscape photographers? Photography has entered the 2 1 century, and the wave of electronic and fully automatic small cameras has greatly weakened the personal influence of photographers. Aperture speed is controlled accurately by programming. Automatic camera, an advanced weapon, can ensure that most people can take photos with better imaging. Therefore, there are more and more popular images. At the same time, although the automatic camera is very convenient to use, it still cannot meet many special requirements of photographers and creators in some aspects, nor can it replace the special role of manual large-format cameras. In this case, those large format cameras with simple structure and complicated operation, which always maintain the traditional manual operation mode, can meet people's requirements in a unique way. From photometry to exposure, from framing and composition to color control, photographers need to use their own experience and wisdom, and make appropriate adjustments to images, so as to achieve creative and technical perfection, mobilize various technical expressions of innovative ideas, and achieve unique and perfect shooting requirements.

Today, the time seems ripe for us to talk about high-quality images. After nearly 20 years' development, photography in China is not what it used to be. Professional photographers and photographers have been able to own cameras such as Canon, Nikon and Minolta, and almost all the advanced cameras in the world can be seen in China. Photo studios were all the rage in the mid-1990s, and commodity photography gradually flourished, with photography studios everywhere. When people talk about photography, they are no longer satisfied with simple photography, but pursue the embodiment of perfect images, so they must win their place on the world photography stage. Many China photographers' works are not only exquisite in composition, saturated in color and rich in layers, but also not inferior to foreign photographers in the skillful use of equipment. Many commodity photographers in China not only shoot the products of domestic enterprises, but also undertake the shooting of a large number of foreign famous brand products, such as IBM computers, Motorola and Ericsson mobile phones, Canon copiers and so on. This shows that the process of China's integration with the international photography level has been greatly accelerated. Therefore, we have every reason to believe that a large-format camera that can not only meet the superb shooting technical requirements, but also fully display the photographer's creativity will definitely be used by more photographers and photographers! 1. High-definition and high-quality images brought by large format.

The image taken by the large format camera is larger in size, clear in imaging, real in texture, delicate in tone and tone level, and more saturated and realistic in color.

The area of a 4X5-inch loose leaf is 13 times that of 35mm film, a 5X7 loose leaf is 25 times that of 35mm film, and an 8X 10 loose leaf is 50 times that of 35mm film. For a simple example, when you need a picture of 8X 10 inch, you must use a 35mm negative (24mmX36mm) to enlarge it by more than 50 times, and a 4X5 inch negative (99.6mmX 125.4mm) only needs to enlarge it by 4 times. However, if an 8X 10 inch negative (20 1.7mmX252.5mm) is used, only 1: 1 is needed to print the proofs directly. The clarity, graininess, tone and texture of the image brought by large format photography are incomparable to small and medium-sized cameras, and they have absolute advantages unless you don't need them for your purpose. 2. Have a wealth of interchangeable lenses.

Generally, there is an illusion that the lenses of large-format cameras are fixed-focus lenses, with few types and small selection range. In fact, in the large format camera, there are no lenses belonging to a certain brand camera, only some lens plates dedicated to different brands of cameras. In other words, all brands of lenses can be used in any brand of cameras as long as they are made for large-format cameras and installed on lens boards of different brands.

There are several manufacturers that produce large-format lenses, such as the large-format Nicole series lenses produced by Nikon Company of Japan. The focal length is between 65 mm and 1200mm, and it is divided into five series and 26 models. The large-format Fuji Dragon series lenses produced by Fuji Company in Japan have a focal length of 65mm-600mm, and there are 7 series and 26 models. The large-format Schneider series lenses produced by Schneider Company in Germany have a focal length of 47mm-800mm and are divided into 6 series * * * 34 models. RODENSTOCK series lenses with large format produced by Rodenstock Company in Germany have a focal length of 45mm-800mm and are divided into 7 series ***37 models. In addition, there are SINARON series lenses produced by famous Swiss companies, with a focal length of 65mm-600mm and 4 series and 24 models. 3. It has the function of moving and adjusting the imaging perspective effect and focal plane.

Large format cameras, especially monorail cameras, have a very flexible function of shifting axes. Generally, the optical axis of the photographic lens of a small camera has a fixed vertical cross relationship with the center of the picture. But the optical axis of large format camera can be moved and the angle can be changed. Through such shifting and adjustment, the left, right and upper viewpoints of the camera can be changed within a certain range without moving the camera. For example, you can shoot a mirror object from the front without distorting the object or making the photographer and camera appear in the mirror of the picture. In the case of limited site conditions, some obstacles can be avoided. By adjusting the inclination and deflection of the front group and the back group, some shooting technical problems can be handled skillfully. For example, we can selectively focus on a certain part of an object to make it clear, while blurring other parts and emphasizing the main goal. The geometric perspective effect of the subject is purposely reduced or exaggerated to achieve a special shooting effect. Because the front and rear panels of large-format cameras can move and tilt, they can shoot extremely clear pictures from the photographer's feet to infinity, which is why many landscape photographers at home and abroad who pursue perfect style mostly use large-format cameras. 4. The charm of single lens

Modern cameras often add automatic film winding and continuous shooting device, and film filling is also convenient and fast. On the contrary, large format cameras can only use a separate loose-leaf film box, and the loading and unloading of film is also very cumbersome and inconvenient. But this inconvenience is only one of the advantages of the big format. Because it is a single shot, you can easily change any type of film you want to use, and you can also expose and develop each negative separately as needed to control the required tone and achieve the best effect. We can use ansel adams's regional system theory to strictly control and make every photo when shooting black-and-white movies. It can also encourage photographers to be more planned and thoughtful in the whole process of shooting. Force you not to press the shutter casually, force you to observe and think carefully when shooting, and gradually develop good shooting habits. Not having a camera is not an excellent scene, not pressing the shutter is not a particularly good time, and the understanding of taking pictures is gradually enhanced. Develop a calm, orderly and thoughtful shooting mentality and habit.

Therefore, for commercial advertising, industry, architecture, landscape and even advanced portraits and other photography activities that require extremely high quality and special effects, large-format cameras are irreplaceable creative tools and necessary special tools for professional landscape photographers and advertising photographers. In the field of photographic art creation, large format camera plays an irreplaceable special role. Large format attachment system

A remarkable feature of large-format cameras is that there are many accessories, which are basically necessary. Generally, there are lens, film box, exposure meter, crown cloth, cable, viewfinder magnifying glass, hood, brightness enhancement screen, image viewfinder and so on.
