Would you need a 12% gray card to get the correct exposure using an ANSI calibrated meter (i.e., is the luminance setting for ANSI really equivalent to 12% reflectance?)?

那么我們是否需要一個12%的灰卡來得到一個正確的曝光值，當(dāng)我們使用的是ANSI標(biāo)準(zhǔn)的測光表影音先锋国际资源？

Although factors that affect the quality of an image captured at high speed include scene luminance, aperture size (f-number, f/#), shutter speed, and field of view, a simple calculation can determine the approximate shutter speed needed for such an application.

盡管影響高速捕捉圖像質(zhì)量的因素包括場景的亮度日日干干人人爽爽、鏡頭大小、快門速度和視野日韩91视频，不過對于這樣的應(yīng)用場合可以很簡單就計算出大致所需的快門速度欧美人妻三级片。

Therefore,a series of experiments on polishing quality of an ultra-smooth surface and polishing time were designed,which was judged according to the size of a scattering facula and luminance under the condition of total reflection.

為此，對所加工的全反射棱鏡的超光滑表面拋光不同的時間乱伦激情图片，并在全反射條件下超碰狠狠亚洲，根據(jù)全反射棱鏡背向散射光斑的大小和亮暗的程度來判斷所加工超光滑表面加工質(zhì)量的檢測方法，最終給出超光滑表面的拋光質(zhì)量隨拋光時間的變化国产黄色巨乳。

Electric design in making medicament from power distribution electric, luminance, annihilating germ by ultraviolet radiation, fire alarm, wire and tube and so on, was discussed briefly in this paper.

At last the luminance and the guide number of the flash lamp is measured respectively by illuminometer and digital camera.

最后采用照度計和數(shù)碼相機(jī)對實現(xiàn)的LED電子警察閃光燈進(jìn)行發(fā)光照度和閃光指數(shù)的測量。

This paper addresses the principles and process of the constitution of this standard and introduces the contents from the aspect of nocturnal environment safety and security , light pollution control, floodlighting luminance of building, artistic effect of lighting, lighting devices, and lighting power supply in detail.

上海市城市環(huán)境照明規(guī)范》于2 0 0 4年9月1日開始實施www路99riav路com，本文闡述了該規(guī)范制訂的原則和過程美国一级A片aaa久久，并從夜間環(huán)境的安全與安保、光污染的限制国产第一页精品12页、建筑物泛光照明亮度久久久久性爱、照明藝術(shù)效果、照明設(shè)備和照明供配電等方面詳細(xì)介紹了規(guī)范的內(nèi)容国产高清自拍高清。

For floodlighting , the luminance and the color of the lighted object depend not only on the power and the color of the illuminant, but also on the color of the lighted object (the spectral reflectance of the surface), so, if we choose the optimum matching illuminant for the lighted object in lighting design, we can get excellence and energy efficiency result.

泛光照明中人人摸,人人操，被照體的亮度大小、顏色變化等視覺效果不但與電光源的功率和光色有關(guān)你懂的在线观看视频网站，而且還與物體色等有關(guān)播播影院私人影院性播影院，所以在進(jìn)行照明設(shè)計時，應(yīng)選擇光源色和物體色相匹配的光源AV免费网站天堂网，這樣才有可能使泛光照明效果較好日韩三级片av，而且達(dá)到照明節(jié)能的目的。

Gamma Screen luminance as a function of video voltage approximately follows a mathematical power function of the input video signal, the exponent of which is called gamma.

Besides both appearance and luminance, the safety of a headlight is a more important issue in the industry.

除外型和以外com碰，前燈的安全在工業(yè)中是一個比較重要的議題。

They were illuminant ,visual field,background,and luminance.

主要探討了影響色差評定的因素：光源欧美欧美欧美性爱网、視場一级日本特黄牲交大片在线、背景、照度色色五月天导航。
