Digital photography is still new enough that most of us have yet to form an opinion about it, much less develop a point of view.
But this hasn’t stopped many film and computer buffs from agreeing on the early conventional wisdom about digital cameras--they’re neat peripherals for your PC, but they’re not suitable for everyday picture-taking.
The buffs are wrong: the smart money is on digital cameras--or soon will be. (95)
The latest digital cameras cost hundreds, not thousands, of dollars and they more closely emulate the picture quality we’ve come to expect from film cameras.
But more than anything else, digital cameras are radically redefining what photography means and what it can be.
Film and prints are not going away any time soon. (96)
But even with improvements the venerable medium of photography as we know it is beginning to seem out of step with the way we live.
In our computer and camcorder culture, saving pictures as digital files and watching them on TV is for millions of Americans no less practical--and in many ways a lot more appealing--than fumbling with rolls of film that must be sent off to be developed.
Paper is also terribly unforgiving. (97)
Pictures that are incorrectly framed, focused, or lighted are nonetheless committed to film and ultimately processed into prints.
The digital medium changes the rules. Still images that are captured digitally (with light sensitive semiconductors known as a charge-coupled devices, or CCDs) can immediately be shown on a computer monitor, a TV screen, or a small liquid-crystal display (LCD) built right into the camera. (98)
And since the points of light that constitute an image are saved as a series of digital bits in electronic memory, rather than being permanently etched onto film, they can be erased, retouched, and transmitted online.
选项
答案
而且由于构成图像的光点是以一系统数字比特的形式储存在电子存储器中,而不是永久性地固定在胶片上,所以可以抹掉、修改和联机传输。
