胶片

Antihalation Backing: A dark layer coated on or in the film to absorb light that would otherwise be reflected back into the emulsion from the base.

在胶片上或胶片中涂的一层黑色涂层，以吸收光线，否则光线会从片基反射到乳剂上。

This paper describes the importance of using correctly the characteristic curve of the X-ray films in the radiographic detection.

阐述了正确运用X光胶片特性曲线在射线检测中的重要性，研究了X光胶片特性曲线在射线检测过程中曝光参数选取时的实用价值及其相关应用。

The unsuspecting photographer focuses with the lens wide open to place the circle of least confusion at the sensor position b, and, taking the actual picture at a reduced aperture, he is unaware of the ensuing focus shift that prevents him from getting the best out of the lens.

一个经常使用全孔径来拍摄的摄影师会毫不犹豫地把胶片放在B点，但是如果他不改变胶片的位置，当他使用小光圈的时候，事实上，他就不可能充分利用这个镜头拍到最好的照片了。

Based on the experiments, we come up with two methods of digital imagingof gun camera: The first one is to change the gun camera and make it as aspecial digital imaging system. If so, the gun camera will not support thefilm cassette. The second method is to enable the digital imaging cassette tofit the gun camera.

在实验的基础上提出了感光式胶片照相枪数字化成像的两种方案：一是改造照相枪，使之成为专门的数字化成像系统，这是一个比较优化的数字化成像系统，但改造后照相枪将不兼容感光胶片式暗盒。

Moreover regardless of adopts what kind of existence the existent solution, digit imaging system's latitude must be a certain that cannot be intervened artificially value on the physical level after leaving factory. Some digital cameras are known as alterable latitude, but they change camera's latitude by past treatment through DSP. So users cannot change latitude, light-shade transition or color transition as film camera just by replacing film's type. Now the civil camera's minimum ISO is 50. This value is discommodity for users to photo by the long exposure or other similar mode.

另外无论采取何种目前存在的解决方案，由于目前具有动态范围可调功能的数字照相机都是针对CCD所采集的数据进行再处理，因此，数字成像系统物理层上的宽容度动态范围始终是一个人工不可干预的固定值，这样的话，用户无法像胶片一样仅仅改变胶片型号便能实现宽容度和色彩过渡的改变以方便画面的创意，而且目前民用照相机感光度的最低值一般为ISO50，这个值在进行类似长曝光等方式的创意摄影时仍存在较大的不便之处。

Choosing different values of red, green and blue to form different colors, masks composed of these colors can be obtained by color film recorder.

通过选取不同RGB值组合成特定颜色，由彩色胶片输出仪输出这些颜色组成的彩色掩模，获得的彩色胶片掩模用来线性调制曝光量，从而实现二元光学元件台阶深度的线性化。

拷贝黑室边光芒较黑，夺目不克不及不兵阴图陡网胶片与其他胶片纯不收在一路，以免不柔进厂的青工误认为是未搁置功的胶片给裁切了。

Color film was difficult to get during World War II, but a friend gave him a three-foot chunk from a long roll.

二战中，人们很难找到彩色胶片，但是埃比的一位朋友从一长卷彩色胶片中截了三英尺长的胶片给他。
