Chapter 1, chapter 23 digital photography systems, section i comparison of digital photography with traditional photography images taken by digital cameras are already digitized and can be entered directly into the computer for processing without any further digitization. (i) the type of scanner is broken down by the type of image that can be scanned, with the photo scanner and the film scanner. By scanning, there are two types of pv and ccd tablet. There are two types of cabling and portable equipment, defined by ease of transport. (ii) main factors affecting scanner performance
2. Resolution, colour reduction and scanning speed. Ii. Digital image processing systems computers and software (i) computer hardware configuration (i) computer hardware configuration (ii) computer software (ii) computer software has two main categories: systems software and applications. Systems software is used primarily for the management and movement of computer system processors, storage units, input equipment, output equipment, etc. Application software is used to address specific application issues on the basis of normal work on system software. Three, digital image output systems, which are computer-processed digital images, can be used to export film (negative or positive), photo (print photos) or photo cd-roms, respectively, from different output devices. The equipment used to export film is the digital film recorder. The work of the digital film recorder can be divided into three processes: the conversion of digital image files into specific analogue telecommunications numbers; and the conversion of analogue telecommunications into light signals
Three or three are for the light signals to be recorded on the photo-photo-photogram film, thus becoming negative or positive. Section iii. Computer processing of digital images, computer processing of digital images, is an important link in modifying, adjusting, cutting and other specialty processing of images to improve their quality, improve their visual effects, enhance the flow of information or enhance their appreciation. One, digital image processing software, layer effect, professional photography tools, special effect filters, colour correction tools, two, digital image processing techniques, modern digital image processing systems that can be used both for black and white image processing and for colour image processing. When dealing with black and white images, it is possible to adjust the image structure, contrast, and sense of quality; it is possible to delete the redundant components of the picture; and it is possible to create a variety of special effects that are highly operational and far beyond the operational scope of the traditional "scene room stunts". In processing colour images, in addition to completing the same operations as the above-mentioned black and white images, colour can be corrected, adjusted in terms of colour three properties (colour, light, saturation) and operating intuitive, simple. The vast majority of news photographers are wary of computer-based video-processing technology, respecting the “first image” taken from the scene, from the point of view of journalism's pursuit of journalism and authenticity, with as little modification as possible, or with a focus on filming rather than on technical processing; much less using “digital technology” as a means of falsifying, otherwise people lose confidence and trust in news photography, which ultimately leads to the loss of its own value or even its demise. I don't know,
