Camera manufacturers typically advertise their products by citing the resolution of their camera’ lenses, the resolution of a lens being the degree of detail the lens is capable of reproducing in the image it projects onto the film. Differences between cameras in this respect are irrelevant for practical photography, however, since all modern lenses are so excellent that they project far more detail onto the film than any photographic film is capable of reproducing in a developed image. The argument depends on assuming which one of the following? (A) The definition of the term “resolution” does not capture an important determinant of the quality of photographic instruments and materials. (B) In determining the amount of detail reproduced in the developed photographic image, differences in the resolutions of available lenses do not compound the deficiencies of available film. (C) Variations in the method used to process the film do not have any significant effect on the film’s resolution. (D) Flawless photographic technique is needed to achieve the maximum image resolution possible with the materials and equipment being used.(B) (E) The only factors important in determining the degree of detail reproduced in the final photographic print are the resolution of the camera’s lens and the resolution of the film. 这题为什么C不对呢?原文中有一句话我读了很久不明白是什么和什么比 "Differences between cameras in this respect are irrelevant for practical photography, however, since all modern lenses are so excellent that they project far more detail onto the film than any photographic film is capable of reproducing in a developed image" 这句话的意思我想是说用resolution区分camera其实在现实中没有意义,原因是大家的lenses都很好,可以投射更detail的东东到film上去,比什么什么更加detail 但是这个比的东西怎么是film自己呢?film怎么自己project自己呢? 谁能够给我指点一下迷津呀,谢谢 |
