“ We now took out a patent for the new optical wonder, and having thus secured the invention from that piracy and robbery which too often dog the otherwise successful steps of inventors, causing nearly every patent to be called by the legal fraternity a damnosa hereditas, we looked about for a good place—hall or theatre—where the illusion could be started. None better could be thought of than the old Royal Polytechnic, where we offered at a moderate sum per week to produce it, paying for every stick, decoration, or engraved looking-glass ourselves. ”

“ Place a mirror over the face of a computer screen. Then you can see where the glare is coming from—which window, which lamp; for all you know, the source could be a brightly colored painting or a glassed-in print.
151Try to rid your office of glare instead of using a filter. “I believe in avoiding a broken arm rather than putting a splint on it afterward,” says Harry Snyder. If you need a filter, however, here are possibilities:
1. Coatings or etching applied during manufacture of the video displays. They needn’t harm the viewing quality noticeably. ”

“ Transparencies can be made same size of negative by contact and exposure to artificial light, or enlarged or reduced in the camera by daylight, with equal perfection in result. To make transparencies by contact place one of the Keystone thin crystal glass transparency plates over the negative in printing-frame, lay piece of dark soft material over it, close down the back, and expose to the light of the lantern or to a gas flame or other artificial light, for 10 to 30 seconds, according to density of negative, at a distance of 20 inches from the flame. ”

“ If you want a really brilliant, clear, white light, you must trim the lamp yourself. A small piece of pale blue or neutral-tint glass interposed between the lamp and the microscope has a wonderful effect in diminishing the yellow hue which belongs more or less to all artificial lights which are produced by the combustion of oil or fat. We have no doubt but that in a few years we shall be rid of the clumsy and dirty machines that we call lamps, and have substituted for them the pure brilliancy of the electric light. ”

“ When an opaque shade is placed before the lens of either of the lanterns, to prevent the light from reaching the screen, the previous confusion becomes instantly clear and distinct, and the church or the landscape is seen without any interfering images. If the opaque screen be gradually withdrawn from one lens, and at the same time drawn in an equal degree over the other, the different objects will again be mingled, and those in the one scene will predominate over those in the other in proportion to the relative quantities of light permitted to issue from each lantern to the screen. ”

“ And as with the water torture, the fluorescents’ victims may be captives of sorts. How many people can dictate the lighting in their companies’ offices? Many. But not all. So the letters and numbers on their screens, the facts they need to do their jobs, may compete with the glare beamed off the glass. ”

“ The blinding effect of a brilliant light-source is easily proved by looking at the sun. After a few moments great discomfort is experienced, and on looking away from this brilliant source the eyes are temporarily blinded by the after-images. When this happens in a factory as the result of gazing into an unshielded light-source, the workman may be injured by moving machinery, by stumbling over objects, and in many other ways. ”

“ I mastered photography to such a degree that the manufacturers of one of our finest brands of print paper once sent the manager of their factory to me to learn how I handled it. He frankly said that they could obtain no such results with it as I did. He wanted to see my darkroom, examine my paraphernalia, and have me tell him exactly how I worked. As I was using the family bathroom for a darkroom and washing negatives and prints on turkey platters in the kitchen, I was rather put to it when it came to giving an exhibition. ”

“ The person who lends a book to a friend or takes a chapter into class is very different from the company with a printing press that chooses to reproduce ten thousand copies and sell them. The photocopier and the VCR make that distinction fuzzier, and the networked computer threatens to erase it altogether. 37
So how are things different today? If you are a person who routinely uses computers, the Internet, or digital media, imagine a day when you do not create—intentionally and unintentionally—hundreds of temporary, evanescent copies. (If you doubt this, look in the cache of your browser.) ”

“ They’re an expensive way to strain your neck. “The normal line of sight for human beings is fifteen degrees below horizontal,” Waters says. “People normally look slightly down even when they hold their heads up.” Needless to say, you and your neck will come out ahead if, using an old Apple II, you don’t set the monitor atop disk drives resting on the computer. Ignore the ads showing this compact pile. Their purpose is to sell computers, not save necks.
Lighting Bright fluorescents are to computer users’ eyes what a drip, drip, drip, is to the foreheads of Chinese water-torture victims. ”

“ The commonest form of print is on paper, although the most satisfactory print from the photographic standpoint is the transparency on glass or celluloid film.
Transparencies.—Transparencies are made by the regular photographic processes of exposure and development, on glass plates or films placed in contact with the negative, or in the appropriate position in an enlarging camera. The sensitometry and the terms used to describe the qualities of plate or film for this purpose are those already given in connection with the general discussion of plates and films. ”

“ There can be no doubt that, in most of its practical applications, transparency is the fundamental and essential property which leads to the employment of glass in the place of either stronger or cheaper materials. By transparency, in this sense, we wish to include mere translucence also, since very frequently it is as necessary to avoid undisturbed visibility as it is to secure the admission of light. ”

“ Besides, in the new age of electronic decisions, it was state-of-the-art, making up in technology what it lacked in spaciousness. Installed behind the dark walnut panels that covered three of the walls was the latest in high-tech electronic equipment, including a variety of telecommunications terminals, video monitors, and apparatus for projecting and manipulating images on the large screen on the fourth wall—normally concealed by a drawn curtain but now open and ready. ”

“ An artist who views color subjectively and is rarely familiar with the spectral basis may match a green leaf perfectly with a mixture of pigments. A photographic plate, a visual filter, or a spectroscope will reveal a difference which the unaided eye does not.
Some time before the Great War began, it occurred to the writer that colored filters could be utilized in aiding vision by increasing the contrast of the object to be viewed against its surroundings. [9] Studies were made of various filters, made with the object of the experiment in mind, in viewing the uniforms of various armies. ”

“ What’s more, the culprit needn’t be just the fluorescents that light so many American offices.
“The window with sunshine streaming in may still be a psychologically gratifying link with the outside world,” says Eisen, “but it spells plain eyestrain and perhaps headache for every VDT operator within range of the glare.” Even brightly painted walls can sin here.
So can glossy paper. In fact, any paper is bad in one over-powering way. The proper lighting level for paperwork is much higher than for computer work. And yet most computer operators have yet to see the much-touted paperless office. ”

“ Investigating locks and burglar alarms, you’ll learn that your computer may be able to protect itself. How? Some gadgets can let only card-carrying employees—your people with magnetic cards—enter a room. And they can tie into the computer to save you money. The same applies to burglar alarms. Of course, you might want nothing fancier than a strong lock bolting your computer to a heavy table. Don’t spend more than the data are worth to replace. ”

“ The lighting engineer has been a natural evolution of the present age, for the economic aspects of lighting have demanded attention. He is increasing the safety, efficiency, and happiness of mankind and civilization is beginning to feel his influence economically. However, with the advent of adequate, efficient, and controllable light, the potentiality of light as an artistic medium may be drawn upon and the lighting artist with a deep insight into the possibilities of artificial light now has his opportunity. ”

“ Manufacturers of interoperable devices such as computers and software, game consoles and video games, printers and toner cartridges, or automobiles and replacement parts may employ a security system to bar the use of unauthorized components. To “unlock” and permit operation of the primary device (i.e., the computer, the game console, the printer, the car) , the component must contain either a certain code sequence or be able to respond appropriately to an authentication process. ”

“ Until the latter part of the nineteenth century artificial light was considered an expensive utility, but as modern lamps appeared which supplied adequate light at reasonable cost attention began to be centered upon utilization, and the lighting engineer was born. Gradually it is being realized that artificial light is no longer a luxury, that it may be used in great quantity, and that it may be directed, diffused, and altered in color as desired. ”

“ My father has told me that there were frequent quarrels between the glass-makers and the mirror-framers because, you see, the framers wanted to learn the secret of making the mirrors, and the mirror-makers were jealous of the skill of the framers and feared the frame would be more beautiful than the mirror itself and so overshadow it. Then in 1600 the French stole from our people the secret of mirror-making and began turning out mirrors not only as good, but in some respects better than the Venetian ones. ”

“ Television-based systems are growing cheaper; and someday your portable TV may have a built-in computer, a socket for a keyboard, and a flat, high-resolution screen fit for word processing and electronic mail. Call it a Vu-Write. Make it a first-class color television. But also a computer suited for clerks and professionals alike. Give it a memory system less quirky than floppy disks. Develop idiot-proof software selected by simple switches. Mass-produce a Selectric-style keyboard, detachable, or, eventually, a good voice recognizer. ”

“ Close on the heels of the magnetic ink readers came those that use the principle of optical scanning, analogous to the method man uses in reading. This breakthrough came in 1961, and was effected by several different firms, such as Farrington Electronics, National Cash Register, Philco, and others, including firms in Canada and England. We read a page of printed or written material with such ease that we do not realize the complex way our brains perform this miracle, and the optical scanner that “reads” for the computer requires a fantastically advanced technology. ”

“ A limited number of specially prepared printed books can likewise be illuminated. But the greater the number of copies, the less labour may be spent on each one, and the more their illumination tends to be simple “rubrication”—adding coloured capitals, flourishes, and the like (see p. 127) . And, if a large edition is to be decorated, the printer must be content to use black, or black and red, in woodcut or “process” work (see pp. 365, 372) .
Illumination proper may be defined as the decoration by hand, in bright gold or colours, of writing or printing. ”

“ Artificial light in general is more satisfactory than natural light for many kinds of photographic work because through the ease of controlling it a greater variety of more artistic effects may be obtained. In ordinary photographic printing tungsten lamps are widely used, but in blue-printing the white flame-arc and the mercury-vapor lamp are generally employed. Not many years ago the blue-printer waited for the sun to appear in order to make his prints, but to-day large machines operate continuously under the light of powerful artificial sources. ”

“ This is especially true because so much of the horrible drama and revelation came from a mere study of the omnipresent mural carvings. Our flash-light photographs of those carvings will do much toward proving the truth of what we are now disclosing, and it is lamentable that we had not a larger film supply with us. As it was, we made crude notebook sketches of certain salient features after all our films were used up. ”

“ There are a quarter million optical discs—the cutting edge technology of the 1980s—that depend on software and hardware no longer on the market. All of these technologies are less than a century old, and yet, the materials may be gone. ”

“ After all, it was well and good to talk about selling someone the 24 hour right to a video, or the right to move music onto an iPod, but not the right to move music from the iPod onto another device, but how the Hell could you do that once you'd given them the file? In order to do that, to make this work, you needed to figure out how to stop computers from running certain programs and inspecting certain files and processes. For example, you could encrypt the file, and then require the user to run a program that only unlocked the file under certain circumstances. ”
