一、前言景物细部的还原能力是照相胶片的一项主要性能,也是照相科学研究的重要课题。多年来,这一性能均以解象力作为它的测定指标。但实践中发现,解象力与画面的实际效果有时并不一致。对此,国外有关科学工作者曾作了仔细研究,证明解象力确有其局限性。 First, the foreword Detailing the ability to restore the photographic film is a major performance, but also an important issue in photographic science. Over the years, this performance is based on the resolution of its determination of indicators. However, in practice, it has been found that the actual effects of resolution and picture are not always the same. In this regard, foreign scientists have made careful study to prove that there is indeed a limitation of resolution.
