[Home Theater Network HDAV.com.cn] " Fa Lin feeling", according to the literal explanation, there should be a feeling of non-forest. The so-called non-forest, refers to FILM, which is the traditional silver salt film. So if you understand it literally, the so-called non-forest sense refers to the image that is expressed, which has the unique characteristics of traditional silver salt film imaging. Nowadays, digital video products are popular, so the non-forest sense is more like the image taken by the digital camera camera. The image has the texture of traditional silver salt film. So what does this non-forest feel at the end? Since non-forest sense is a feeling of image, then it should be a characteristic feature of the image, and since it is a feature of graphic images, then probably It can be expressed by the following parameters: 1. High contrast . The traditional silver salt film has a perfect reflection characteristic on the optical signal, so the resulting image has a higher contrast than the digital product; this is more "transparent". 2, the color reproduction is accurate , especially the reduction of the pure color is accurate. Because the imaging units of mainstream digital products are CCD or CMOS, the problem of interpolation calculation is inevitably involved, and the interpolation operation will reduce the color reproduction accuracy of the image, especially the reduction of the pure color is not accurate enough. This is more "bright" and more "bright". 3. The resolution is high . The photosensitive particles of the traditional silver salt film are very delicate, so the theoretical resolution is very high, and the resolution of the generally formed image is higher than that of the digital product. This is more "fine". 4. The characteristics of the defects are different . The defects formed by the traditional silver salt film are generally fine and uniform, both in the bright part and the dark part, and the defects of the digital image are generally in the dark part, and the particles are large and the jitter is obvious. It is more "grainy", 5, low illumination performance is different , because the cooperation of traditional camera and film is relatively mature, through the adjustment of the aperture of the aperture, it can be better to complete the shooting under low illumination, and the digital products are insufficient in this aspect, such as lying The section of the Tiger Hidden Dragon roof fight is perfect. This is more able to "sink down" and more "deep". 6, the color scale is too delicate , because the imaging principle is different, the traditional non-forest image, color media tends to infinity, and digital products, whether it is 1 billion colors or 60 million colors, there is always a limit, this is Excessively more "smooth", 7, scratches , because the traditional non-forest saves the image through physical means, it is inevitable that there is no physical damage such as scratches, so the embarrassment of this image has become an aspect of the non-forest sense that the enthusiasts appreciate, so-called More "natural", more "vicissitudes", more "non-forest". 8, progressive scan , the traditional movie does not have scanning problems, because the image is composed of a complete photo of 25P continuous, and the digital camera basically uses interlaced 60I scanning imaging, so in the performance of the exercise People feel different. Therefore, the things that come out of the digital camera are very "television" and "digital", and the things that come out of the film camera are very "movie" and "non-forest". 9, color halo , because the traditional film needs to be washed, so if we look at the edge of the image, we will find some color halo, and the digital camera will not have such features, except for " The problem of purple fringing, the image produced by digital products should be sharper and even show the jaggedness of pixels, so the things that are not from Lin are more "warm", while the things that are digital are very "hard", basic The so-called non-forest sense is the synthesis of the above nine image characteristics. But what I want to say is that with the advancement of technology, the image quality of digital products is getting better and better. At present, the image quality of several digital cinema cameras produced by SONY can be compared with the traditional non-forest camera. Comparable, such as Star Wars 2, 3 are all taken with digital products, but if you don't say it, the average person can't tell. At the same time, I don't agree with some of the arguments. For example, the three shots are more non-forest sense. How is this possible? No matter what projector is used, it is used to restore the image. If the accuracy is restored from the image. In terms of speaking, the most accurate projector must be a 3DLP machine. An inaccurate thing, to restore a movie shot with a non-forest, how can it be more non-forest sense than accurate restoration? Also, the image produced by the film projector is also more non-forest-like, and I can't agree that the dark part of the film projector can't be handled very well anyway. This is the same as the LCD projector, which is not accurate anyway. To restore the image, of course, there is no more so-called "non-forest sense". In addition, a fatal weakness of traditional non-forest equipment is the focus problem, because non-forest is mechanically leveled and placed in the imaging area. We can imagine that a soft non-forest must have subtle unevenness because the camera equipment is high. Precision machines, a little bit of focus can make the image resolution drop several times, so the traditional 35MM non-forest film, now, most of the resolution will not work. 35MM film, the theoretical horizontal resolution can reach more than 4000, but we can now see through the digital HDTV, the resolution of most traditional non-forest movies is basically around 720P, although some on 1080, but the image blurry. Really 1080P resolution point-by-point clear movies, only recently digital camera shooting, such as Star Wars 3, Harry Potter and the Goblet of Fire and the City of Sin. From this point of view, it is only a matter of time before digital replaces traditional non-forest. I guess it should be no more than five years. The market of non-forest in the movie will drop below 50%, and in five years, non-forest will complete history. The mission faded out of the rivers and lakes. At that time, perhaps the non-forest sense became a derogatory term, not the fever effect pursued by the fans today. In my opinion, most of the "non-forest sense" is a cloud of people, I don't know why, whether it is fever or fever, the degree of burning is accurate, it is the first, if it is accurate, what is not useful, These so-called feelings of the sense, most of the unclear fever nouns, do not study.
