一般认为低照明介于15-30英尺烛光(照明单位，指每英尺距离内之照度)，高照明介于50 - 100英尺烛光之间。
Low light levels are considered 15-30 footcandles, and high light levels are considered in the 50-100 foot candle range.
不同的相机在低照度条件下长时间曝光拍摄的表现差异很大，因此建议从iso 800起调，并相应地进行调整。
Each camera model react differently during low-light long exposures, so start at ISO 800 and adjust accordingly.
固定的准星有发光嵌件用于低照度条件。
Fixed sights have luminous inserts for low light conditions.
使得图象更为清晰，抑制了在低照度下拍摄经常出现得颗粒性和写噪声。
As a result, images are clearer, and the graininess and white noise that often appear when shooting in low light are suppressed.
目的：研究低照度作业人员营养干预对血浆蛋白、血浆游离氨基酸含量及夜视功能影响。
Objective:Investigate the effects of nutritional intervention on dark adaptation function and plasma protein level, serum essential amnio acid contents in operator working in low illumination.
警示器包括太阳能电池，蓄电池，以及在环境低照度和晚间用以发光元件选控的电路器件。
The warning marker includes solar cells, storage batteries and electrical circuit apparatus for selectively illuminating the light elements during low ambient light and nighttime conditions.
更大的感光元件通常也意味着更好的表现质量——全画幅在低照度、高感光度时会有更好的表现。
The larger sensor also means that - all other things being equal - full frame cameras will produce the best results in very low light and at higher sensitivities.
针对传统去噪方法会导致图像细节模糊的问题，提出一种低照度条件下的图像自动降色去噪方法。
To resolve the problem that the traditional de-noise methods will blur the detail of image, this paper introduces a new method to de-noise the image noise in low light.
该摄像机能保持彩色模式或在低照度条件下自动转为黑白模式。
The camera can remain in color or automatically shift to black-and-white in low-light conditions.
产品简介：微光夜视观察镜，是供夜间低照度条件下对目标进行观察用的电子光学仪器。
PRODUCT INTRODUCTION: Nght vision viewers are electronic optical instruments used for viewing under low light level conditions at night .
