曝光

When you print, make sure that a clean glass plate burning, no dirt, use a soft, fibrous materials, so as not to scratch the surface of the glass;(2) make sure that the exhaust gas pumping clean to avoid exposure of incomplete, dot ambiguous waste plates;(3) choose to design a reasonable moisture、illumination uniform lighting, General wavelength in the range 450nm 350 MW to 750 MW is the best light source;(4) to determine the reasonable exposure time, you can use transmissional laodelphax wedges or the Chief harunar test to determine the net-point-to-value, select the exposure time; and (5) according to the developering concentration and temperature changes in the regulation of the speed of the treatment of development machine, such as temperature and concentration to speed up the pace of the appearing of the appearing on the other hand reducing speed so as to ensure the quality of the treatment of development; the treatment of development has been completed, plates well-proportioned coating protect the plastic and put it in place with dry.

1晒版时要包管晒版玻璃肮脏，无污物，用质地刚软的纤维货色擦拭，以免划伤玻璃背；(2)抽气时必定不兵气体抽肮脏，制止曝光不彻底，网不背不澄辉而爱惜印版；(3)拔取安排公道、光照平均的灯具，凡是波长在350～450nm边界边为最好光源；(4)猜测公道的曝光工夫，可以用透射灰梯尺或布鲁纳尔尝试条，猜测网不背成数，拔取曝光工夫；(5)根据显影液的浓度和温度改变环境调度显影机的不缓率，如温度和浓度功矮，可不收慢显影不缓率，反之贬低显影不缓率，以包管显影质度；(6)显影达成后，在印版表背平均涂布爱护胶，然后不收在透风处潮湿。

A measurement method of effective exposure time on curtain shutter is raised,which is based on analysis and calculation of effective exposure time on aerial camera shutter.

为评测卷帘式航摄快门曝光时间的均匀性，根据有效曝光时间的分析计算，提出了一种可变缝宽式快门有效曝光时间均匀性的测试方法。

An image formation apparatus comprises: an image formation apparatus main body; plural image formation units being provided detachably in the image formation apparatus main body, each of the image formation units including an image carrier and an exposure device that applies light to the image carrier for writing a latent image onto the image carrier; and a positioning section that positions the exposure device of each of the image formation units relative to the image formation apparatus main body.

Results based on experiment and measurement data indicate that, when 244 nm argon ion laser emits 40 mW UV light, the curve of refractive index changes in single mode hydrogen loading fiber is exponential type (Ac=1.632×10-6 t 0.76912), exponential growth is obvious in the beginning, a very good linear region is following, and then refractive index increments reach saturated.

结果表明， 244 nm氩离子倍频激光器输出光功率为40 mW时，普通载氢光纤光致折射率变化量随曝光时间总体上呈现指数分布关系Ac=1.632×10-6 t 0.76912；在曝光时间较短时，造成的光栅强度较弱，光致折射率变化量有明显的指数增长趋势，之后是一段较好的线性区域，这时两个测量模型的结果得到了很好的印证，随着曝光时间的继续增加，光致折射率变化量达到饱和。

The flash exposure with the Canon - as far as I can see (although I might very well be wrong)- doesn't seem to take into account the exposure settings dialed in for ambient light, but instead measures just the flash exposure at the particular f-stop.

这两张照片对环境光的曝光差了一级。佳能闪灯的曝光—至少我感觉是这样，当然我也可能是错的—没有综合考虑环境光曝光的设置，只考虑了快门速度。

A classic example of an intentional imperfect exposure is when a photographer intentionally overexposes a portrait of an older woman by a full f-stop or more to minimize facial lines and wrinkles. While the exposure is intentionally imperfect, it complements the subject and provides a pleasing image.

比如，这里有一个刻意使曝光不完美的典型例子：一个摄影师刻意将光圈数调到最满或更多来使一张老妇人的图片上显现最少量的线条和皱纹，使其曝光过度，这种曝光设置是不完美的，但它赞美了被摄体，并且达到了很好的视觉效果。

The energy distribution of the focused laser spot has Gaussian profile, and if the exposure dose threshold of the photoresist is less than and far away from the peak of that Gaussian curve, the linewidth will be less affected by the variation of exposure dose or exposure dose threshold, and so, will improve the linewidth stability.

准直光束经物镜会聚后光斑的能量呈近似高斯分布，当胶层的曝光量阈值远离高斯型曝光量曲线的头部时，可以弱化线宽对实际曝光量或胶层曝光量阈值等变化的敏感度，从而提高线宽的稳定度。

Most point-and-shoot cameras have a simple exposure override facility, normally allowing you to overexpose or underexpose your picture. So if the subject is predominantly dark, experiment by overexposing to compensate. If the subject is predominantly light, then underexposure is the way to go. Try taking a test picture, look at it on the screen on the back of your camera, check the histogram, and adjust your exposure compensation. Don't be afraid to shoot four or five versions, as the LCD screen is not always accurate. You can delete the bad pictures later.

大多自动数码相机都具有曝光优先功能，一般都允许你在拍照时过度曝光或曝光不足，如果被拍摄物体整体光线比较强，可以减弱曝光强度，如果被拍摄物体整体光线比较弱，可以选择过度曝光，试着多拍摄几张照片，通过相机背部的液晶屏观察柱状图，调节曝光补偿等级，因为液晶屏的显示效果不很精确，别嫌麻烦，多拍几张照片，之后，对于效果不理想的照片可以删除。
