Where in the past many saw the camera as a nice accessory or even a novelty, as technology improves the Windows Phone cameras performance its becoming a more influential feature.在以前，手机的拍照功能虽说有用，但是往往都没有被厂家当做主打指标。直到配了1600万象素的HTC Titan II和装载卡尔蔡司认证镜头的诺基亚 Lumia 900 的出现，才为相机领域带来了新的波澜。科技正在不断提升Windows Phone的拍照能力，因此您怎样把手中的相机的性能发挥到极致，就是一件值得动动脑子的事情了。Additionally, as our Windows Phone camera evolves so does the software that drives it. You have more control over the camera these days along with special settings to use effects, adjust exposure settings, and program settings. From your children at play to a stunning sunset to your new pet the camera on your Windows Phone is a great tool for capturing and sharing memories.而且，手机相机不仅仅是镜头在独撑大局，软件支持也是重中之重。现在您的手机相机拥有非常多的设置项目，而且还有数不清的特效供您选用，有了它们的帮助，无论是孩子在夕阳下的欢笑，还是宠物在草丛中的憨傻（甚至陈老师的那啥照）都能手指一点，留作永恒。With all the advancements weve recently seen with our Windows Phone cameras (along with a few suggestions from our readers) its time to offer our guide to understanding the basics of your Windows Phone camera and a few tips on taking pictures. After the break, well cover the principles of photography, the terminology involved, what some of your Windows Phone settings will do, and a few tips to take better pictures with your Window Phone.不过，现在对于相机的使用，常常是网友偶尔发现的一两点，至于系统化是没有的。所以，本文就为此问题组织成文，来帮助各位WP机友拍出更棒的照片来。在下文，我们将讲述您的Windows Phone的相机的工作原理、相关技术、相机设置，以及一些拍照技巧。Windows Phone Camera: The Basics基础篇The basic concept of digital photography is that an image is captured by passing light waves through a lens that eventually hits a imaging sensor. Light is regulated by shutter speeds and apertures to achieve proper exposure. Briefly, the shutter speed is the time a cameras sensor is exposed to light and the aperture (or f-stop) is the size of the opening in the lens where light passes through.拍照从根本原理上说，是光线通过了镜头，到达光线传感器上。良好的曝光效果需要掌握好快门速度和光圈大小。简要说来，快门速度就是相机的感光元件暴露在光线照射之下的时间长短问题，而光圈大小就是镜头有多少部分透光。Your Windows Phone lacks a mechanical shutter or aperture so exposure is regulated by a fixed aperture and the duration your sensor is powered up. Instead of opening a mechanical shutter for 1/125th seconds your Windows Phone camera sensor is powered on for 1/125th seconds.您的Windows Phone并没有机械结构的快门，也没有类似的孔洞，所以所谓的曝光现在就是感光元件延时启动的等待时间。传统的机械式快门的快门时间是125次每秒的速度，而Windows Phone的手机快门也是用1/125秒完成工作。While some cameras will let you regulate exposure manually, your Windows Phone controls all of this based on the amount of light present. You can manipulate exposure on your Windows Phone by tweaking some of the settings (more on this in a minute) but for the most part your Windows Phone runs with it. Once exposed or captured, the image is processed by the cameras image processor and eventually saved in .JPEG format.当然很多相机能够自动完成曝光的全过程，就像我们Windows Phone的相关调整是基于光线强度的。不过你也可以通过自己的设置来进行调整。在照片形成之后，系统会在处理之后为你保存为jpg的格式。Along with exposure controls, your Windows Phone is likely equipped with digital zoom feature to let you move in closer to your subject without worrying with your foot zoom. Digital zoom is accomplished by cropping an image down to a centered area with the same aspect ratio as the original. In a nutshell you are cropping to simulate an increase in magnification. The end result may pull you closer to your subject but in the process you sacrifice image quality. Optical zoom (e.g. your typical zoom lens), which isnt available, provides an mechanical increase in focal magnification without sacrificing image quality.在曝光的相关设置方面，我们的wp拥有数码变焦功能，不管你是走近还是远离物体，都会自动改变成清晰的状态。数码对焦是把物体影像按照原始的样子收入镜头中，然后通过计算发现应该以哪里为焦点，然后映射成对应大小的数码照片。这样的结果就是中心突出，但是会丢失细节。而传统的手动对焦就能做到不失细节，画面精美。One last basic element is the flash. Well, its actually a light. Traditional flashes send a pulse of light the instance the shutter on the camera is fully open. The light on your Windows Phone follows the same principle but lacks the reach and brightness of traditional flashes. The light on the Windows Phone also doubles as a focus assistant lamp. When lighting is low and your subject lacks the contrast to let the autofocus work, the lamp sheds enough light on the subject to attain proper focus.最后的基础知识是闪光灯。没错，这东西本质上就是一个灯。传统的闪光灯通过在快门打开的瞬间开启闪光灯来实现加亮，而现在我们的Windows Phone采用的也是相似的原理，不过不像传统闪光灯那样到处都能照到，也没有那么亮。WP上的闪光灯也能够辅助对焦。在光线不足的地方，或者被摄物体很模糊难以聚焦的场合，闪光灯就会开启，投下足量的光线帮你实现一次成功的定格。Im not a fan of the camera lights and prefer natural lighting. There is a sweet spot where these lights work work like a charm. Too close and your subject gets washed out, too far and things get underexposed. Finding that spot takes practice and when you do, the light can come in handy.我不是十足的闪光灯发烧友，我喜欢的还是自然光线。这两种光各有所长，而且和拍照距离也大有关系。你离被摄物体过远，那么曝光就会不足；距离太近，又会曝光过度。这之间有一个最佳距离，而这个距离需要多多尝试才能找到呢。Windows Phone Camera: Post Script on Digital ZoomWhile I have my reservations on the digital zoom feature on our Windows Phones, the HTC Titan II may have changed our minds a bit. In comparing the 16mp sensor of the Titan II to the 8mp sensor on the Nokia Lumia 900 with the digital zoom applied to its fullest, the image quality was rather impressive on the Titan II. 我以前对数码相机的拍照能力不以为意，但是HTC Titan II改变了我的想法。在对比了1600万像素的Titan II和诺基亚 Lumia 900 的800万像素之后，我震精了。There is more real estate on the 16mp sensor to accommodate the digital crops the zoom feature creates. Resulting in less quality loss to your images. Weve also noticed that the zoom on the Titan II is noticeably more smoother (feels more like an optical zoom) than what you find on any other Windows Phone. For example on the Samsung Focus S, the zoom seems choppy or jumpy as the zoom increases.在那1600万像素的镜头下，被摄物体完美无缺地出现在照片中。超强的镜头带来的近乎无损的拍摄，让Titan II的相片拥有比其他任何Windows Phone更真实、更平滑的效果。就拿三星的Focus S来对比的话，后者的照片在放大之后明显有阶变和锯齿。While the technology behind digital zoom has improved, Im still inclined to rely on my foot zoom than the zoom on my Windows Phone camera. However, if the Titan II is the sign of things to come, I may have to re-think that position.虽然相机背后的科技一直在进步，但是我还是倾向于手动调焦而不是相机自动调焦。不过，Titan II让我的想法有了变化，如果Titan II代表了未来的科技趋向，我会重新考虑我的选择的。Windows Phone Camera: Settings设置篇There are several controls at your disposal that will influence how an image is taken and processed. While these settings may vary from manufacturer to manufacturer, heres a listing of the more common settings and what they control.相机的设置项很多，这些设置项能够明显改变你的照片效果。虽然同一个设置项，对于不同厂家的相机的效果可能有所不同，但是大体上还是差不多符合下面的共通规律的。ISO Level: An image sensors ISO (International Standards Organization) determines how sensitive to light your sensor is. The lower the ISO the less sensitive the sensor is. For example, outdoors on a bright sunny day you may only need an ISO of 60 where indoors in lower light youd use an ISO of 200 or higher. Most Windows Phone cameras ISO settings are set to automatic but if your images are coming out dark, you may try manually raising the ISO. The downside to higher ISO levels is that they tend to produce more image noise or grain that results in poor image quality.高感度（ISO）：相机的ISO不是国际质量体系的意思，而是光照的高感度。说白了就是你的相机对光线是否敏感。这个数值越低，表示你的相机对光的敏感度越低。举例来说，在阳光充足的户外，你的ISO设成60就差不多了，而在室内则需要200才行（如果臭袜子挂满窗户，那么可能还要更高译者马驴哥注）。很多机友的ISO都设为“automatic（自动）”，但是如果你发现这样拍出来的相片亮度不理想，那么你就可能需要手动调节ISO数值了。不过，还有一点值得注意的是，高ISO值意味着更多的噪点，影响画面质量。So to get the best images possible, you can manually lower your ISO for cleaner shots (especially useful on Nokias phones). But remember, this is only good for still objects as the exposure time will be longer resulting in blur if not held steady. If indoors with low-light, aim for ISO 200 or 400 if you can steady the camera. Bonus tip: use the tap-to-focus feature to snap that photo instead of the physical shutter button.所以，为了获得最佳的拍摄效果，一般来说都是把ISO放在比较低的水平上，而诺基亚的相机更是应该这样做。不过值得注意的是，这样做的代价是快门时间变长，如果是静物那还不错，但是动态物体或者你喜欢情不自禁地哆嗦，那就完蛋了。室内的话，设成200或者400还是比较合适的。小提示：最好使用点击画面的触摸对焦而不是物理按键快门哦。White Balance: Different types of light produce varying shades of white. Warmer light often produces an orange or brownish tint while cooler lights results in blue tints. A cameras white balance simply balances the different light sources to produce whiter whites. Most Windows Phone cameras will be defaulted to an automatic white balance with options to select a white balance based on particular lighting conditions such as florescent, incandescent, daylight, cloudy, etc.白平衡（White Balance）:不同类型的光下，所产生的“白色”这个概念是不一样的。暖色调环境下往往偏橙色或者棕色，而冷色调的则偏向于蓝色。相机的白平衡功能可以让相机知道什么是“白”。绝大多数WP的相机采用自动白平衡的方法，当然也可以自己选择白平衡，以适应特殊光线的环境，比如荧光、白炽灯光、日光、阴天等等。Sharpness, Saturation, Contrast, etc.: These settings tell your camera how much of that particular processing aspect you want applied to an image. For example, if you have Saturation set to high the image processor will raise the color saturation levels as it processes your image. You can used these settings to increase or decrease the amount of these processes are applied to your photos for effect or to compensate for harsh lighting, bright colors, etc.清晰度（Sharpness）, 饱和度（Saturation）, 对比度（Contrast）, 等：这些设置项可以告诉你的宝贝相机你到底想要什么特色的图片。比如说，如果你把饱和度设得很高，那么相机在处理图片的时候就会把颜色弄得异常鲜艳。您可以通过合理地设定这些项目来在恶劣环境下依然能拍出优秀的照片，哪怕光线很差，或是眼前模糊，都不要紧。测光方式（Metering）: This is how youre camera measures the light and adjust the shutter speed, aperture and ISO (when set to auto) to achieve proper exposure. There are various metering modes that include spot metering (meters on a specific spot thats usually the center of your viewfinder or your focal point), center weighted (concentrates the metering to the collective area in the center of your viewfinder), matrix or multi-zone (meters several points in the viewfinder and combines the results for a collective reading).测光方式（Metering）：这是调整相机计算光线强度、快门速度、光圈和ISO（自动模式）的项目。测光方式有点测光（一般是以中心为测光位置，也可以是手指点击的对焦点），中心测光（顾名思义），多点测光或者混合测光（基于多点的计算方法）。EV or Exposure Compensation: This setting allows you to manipulate the exposure settings your metering determines will produce proper exposure. The compensation or EV adds or subtracts from this exposure settings. For example if your subject is back lit you may compensate for greater exposure by using a positive EV number (the greater the number the more exposure compensation). If youre compensation for a lot of glare, you would use a negative EV number to lessen the exposure.曝光补偿（EV或者Exposure Compensation）：这个设置项可以帮助你把曝光掌握得更好。给予你所设置的数目，补偿自动加减曝光程度。举例来说，你想拍一个背后有光的“背光物体”，你就需要调节成高补偿模式，使用一个正数，数目越大补偿越强。而如果物体正对着你的面是受光面，那么就该用负数的曝光补偿了。In addition to the basic exposure settings, some Windows Phones have additional settings that influence how your camera performs. In addition, there are third party apps now available that will help you in a similar fashion.对于缺省的曝光设定来说，有些Windows Phone的很多设置都能影响相机的表现。顺便说一下，有些第三方软件也能帮到你。Panoramic Imaging: Panoramas are wide angle views often composed of several images stitched or pieced together. HTC provides a simple, straightforward panoramic feature with their cameras. For the others, you have third party apps such as Auto Panorama that will allow you to take several landscape images and stitch them together to create that panoramic image. The key to taking good panoramas is simple, keep your camera steady and on a constant plane. A tripod is a great tool in helping you take better panoramas.全景拍摄（Panoramic Imaging）：全景拍摄是宽角度拍摄，一般是多幅画面组合成的一张图片。HTC提供了简单的全景功能，而其他的也可以通过像Auto Panorama这样的软件进行自动拼接来实现全景拍摄。想拍好全景并不难，只要你端稳了相机，在一个平面上运动就行。要是有三脚架那就非常简单了。Burst Mode: Burst mode tells your Windows Phone camera to shoot a series of frames or photos quickly. The HTC Windows Phones have this setting built in to allow you to shoot five frames in burst mode. Burst Mode can help capture action shots or help capture impromptu expressions. Say your son acting goofy, doesnt think you can take the picture fast enough and you want to capture as many blackmail photos as possible. If your Windows Phone lacks a burst mode, check out Turbo Camera as an alternative.连拍模式（Burst Mode）：连拍模式就是相机快速而连续地拍摄好几张图片。HTC的Windows Phone可以实现五连拍。连拍模式最适合抓拍一闪即逝的表情或者场景（类似于地毯式轰炸的思路哈译者）。设想你的儿子的可爱表情你超级想拍下来，但是手机没有连拍功能，那你就一张一张地碰运气去吧。所以，如果你有类似的需求，连拍模式这个功能还是值得考虑的。Image Stabilization: While fairly new to Windows Phone cameras, image stabilization has been around for years. With most stand alone cameras, you have small motors that hold the lens or image sensor still when slight movements occur. This reduces the chance of images being blurred by camera movement when slower shutter speeds are used. With your Windows Phone camera, the image stabilization simply raises the ISO to allow for a faster shutter speed to reduce any blurring caused by slight movement of your Windows Phone as you take the picture. The downside is that because you are raising the ISO, you may see more image noise or grain when you use the image stabilization.防抖功能（Image Stabilization）：这个功能已经出现了不短的时间了，但是在Windows Phone上还是新添加的功能。开启之后，内部的小电机就能够自动维持镜头和传感器不受微小晃动的干扰。在低速摄像的时候，这个功能可以有效地防止照片变模糊。在Windows Phone上，开启这个功能就是稍微提升ISO来加快快门速度，减少抖动的影响。缺点和提升ISO的缺点一样，就是会有较多的噪点啦。Red-eye reduction: Red eye is caused by light reflecting off the back of your pupil when a flash is used. Red-eye reduction sends a small pulse of light towards your subject to acclimate their eyes to the brighter light and then the full discharge of the flash occurs.消除红眼（Red-eye reduction）:“红眼”一般是指在人物摄影时，当闪光灯照射到人眼的时候，瞳孔放大而产生的视网膜泛红现象。红眼消除功能则是先用一个弱光来使被摄者的眼睛适应闪光，然后开启正式的闪光灯，这样就能消除红眼了。Macro: On your Windows Phone camera, macro is simply close up focusing. It is not a traditional macro setting (recording the subject at life size magnification) but will get you closer to your subject to record finer detail. Your macro setting is great for flowers, coins, and other small objects. The challenge with macro is making sure enough light gets to your subject because of the close distances. Set to macro, your Windows Phone camera will focus about six to ten inches away from your subject. Your Windows Phone can easily cast a shadow over your subject at those distances.微距拍摄（Macro）：微距拍摄就是很近距离的拍摄。使用微距可以让你离被摄物体很近，把握更多细节。使用微距拍摄可以更好地拍摄花朵、硬币或者其他小东西。不过，想拍好微距必须要充足的光，不然会很糟糕。开启微距模式，你的相机就会自动在6到10英尺（换算后是0.1524米到0.254米译者马驴哥）的范围寻找焦点。不过，小心别让你的相机挡住光了哦。Geo-tagging: One nice feature with your Windows Phone camera is that it can tap into your Windows Phones location services to geo-tag your pictures. Geo-tagging simply adds your GPS coordinated to your images EXIF file. This is a nice tool to remember where you took the picture and with Windows Phone apps such as Image Map, you can pin these locations to a NAVTEQ map. 地理位置（Geo-tagging）：就是在相片信息中添加地理位置。相片有EXIF用来记录相关数据，用地理位置记录功能就能够很好地帮你记住这张相片是在哪里拍摄的了。The downside to geo-tagging your pictures is that if you keep this information on any uploaded photos, with the right software, everyone can see the location. If you prefer to keep your locations private, you can go into your Windows Phone settings under Applications and Pictures + Camera and turn off the option to keep location information on uploaded pictures. Now you can share your pictures while keeping your locations private.相片的地理位置是所有人都可见的。如果你不想让别人知道，那么你可以在Windows Phone的设置里边把它关上。具体方法是，设置-应用程序-图片和相机，关闭地理位置信息。这样就万事大吉了。Smile Detection and Face Detection: Heres a couple of interesting settings that Ive only seen on the HTC Titan II. When turned on Smile Detection will identify your subjects face and when they smile, the camera will take the picture. Face Detection will detect any faces in your photo and adjust the focus to make sure the faces are dialed in just right.微笑快门以及脸部识别（Smile Detection and Face Detection）：这个功能只在HTC Titan II里边出现了。相机可以智能识别被摄物体的微笑，然后在合适的时机拍摄。脸部识别能够让对焦更有效。Windows Phone Camera: Scenes and Effects场景与特效Most Windows Phones will have settings for scenes and effects. Scenes are basically a collection of programmed settings or modes designed to tackle a particular photographic scene. For example, the HTC Titan II has eighteen scene choices ranging from portraits to nighttime to food. In my experience, most Windows Phone cameras will have enough scenes to cover the basics; portrait, landscapes, macro, sports, night, etc.大部分WP都有场景和特效方面的设定。有的也叫做拍摄效果。拍摄场景选项是基于以往经验，对于特殊场合的标准设定方法做了一个综合，来自动帮你拍出好的照片。举个例子，HTC Titan II拥有8个不同的场景选项，从人像摄影到夜晚拍照甚至食品拍摄都行。据我所了解，绝大部分的Windows Phone都有以下场景：人像、全景、macro、运动、夜景等。In addition, to illustrate how the camera software has developed, the Titan II has an Intelligent Auto setting that considers the variables detected by the camera (lighting, distance to subject, focus shifts, etc.) and automatically selects the best scene for that particular picture. Other cameras will have an auto setting under the scenes settings but the Intelligent Auto seems more refined. Such features help take the guess work out using your camera.值得一提的是，像Titan II这样的手机，已经拥有了自动智能设定的功能，可以通过相机的光线、距离、对焦等等自动选择最合适的环境选项。其他的手机就要手动设置了。对比来说，这个功能在拍出好照片方面还是很重要的。Effects are a collection of filters and image processing effects that can be applied to a photograph while the cameras processor is processing the image. For example, the Lumia 900 has five effects that can be applied to images that includes normal, black & white, sepia, negative, and solarized. If youre looking for an old time feel to your picture you may choose the sepia effect. If you like gray scale images, then black and white might be your cup of tea.特效则是滤镜和照片处理效果的集合。比如说，诺基亚 Lumia 900 有五种特效，包括正常、黑白、深色、反色、过度曝光（是这样翻译吗？好奇怪译者马驴哥）。如果你想要拍出老照片的效果，那就选择“老照片”特效吧。要是你想拍出素描一样的图片，那么黑白特效就是专门为你准备的了。Camera effects are a great way to add a bit of creativity and uniqueness to your photographs. If your Windows Phone lacks enough effects to your l
