挑战单反的长焦数码王一一富士X-S1
挑战单反的长焦数码王一一富士X-S1作者：暂无来源：《摄影之友·影像视觉》 2012年第3期富士在发布X-S1数码相机的时候自信满满地挑战18-270mm“天涯镜”和中低端数码单反组合，它的性能果真如此强劲吗？撰文、摄影：王晶编辑：林曦2011年富士X系列数码相机在市场中广受好评，广大消费者用果断掏出钱包的实际行动给予X100和X10这两款X系列高端数码相机很高的评价。
而全新推出的富士X-S1使用了1200万有效像素的2/3英寸EXR CMOS传感器和最大光圈为2.8的24mm~624mm（35mm等效焦距）的超级镜头。
由于感光元件比APS-C画幅要小的原因，富士X-S1在624mm端可以拥有5.6的光圈。
从这两个指标上来看，富士X-S1的镜头配置足可以秒杀不少数码单反的套头了。
外观设计富士X-S1是一款全新类型的桥式数码相机，富士也坚持了X系列高端数码相机在日本制造的传统，让X-S1整体看上去拥有极高的品质。
纯金属打造的操作拨盘，厚实的橡胶涂层带来的极佳的操作手感令X-S1给人非常良好的第一印象。
从外观上看很多人会误认为富士X-S1是一台数码单反相机，类似数码单反的机身造型让这款相机握持起来更有手感。
富士X-S1配备了3英寸可翻转液晶屏，这块液晶屏拥有46万像素，可以在屏幕上轻松设置相机、确认曝光和浏览所拍摄的照片。
这块液晶屏有一个非常实用的“晴天模式”，能够在强烈阳光下看清液晶屏显示的内容。
富士X-S1的电子取景器为0.47英寸，具有高达144万像素的分辨率，可视角度达到了26度，这令我们在取景构图时更为舒适。
在电子取景器左侧拥有一个距离感应器，可以在眼睛靠近电子取景器时自动切换画面，而且使用电子取景器可以在使用长焦拍摄时提高相机的稳定性。
富士X-S1的按键布局和操作按钮和数码单反相机类似，机顶拍摄模式转盘和大多数数码单反一样拥有PSAM模式，参数设置拨轮、曝光补偿、驱动模式和自定义功能按钮可以快速调节相机的拍摄参数。

XDCAM为sony在2003年所推出的无影带式专业录影系统。
2003年10月开始发售SD系统商品，2006年4月开始发售HD系统。
XDCAM的首两代XDCAM及XDCAM HD，使用Professional Disc作储存媒体，媒体和Blu-ray Disc相似及同样可储存23 GB（PFD23，单面）或50 GB（PFD50，双面）数据。
第三代XDCAM EX，使用固态SxS记忆卡。
在2008年，JVC宣布和Sony结盟支援XDCAM EX格式。
XDCAM产品范围包括了摄影机和录影机，作为突发取代传统录影机的格式，容许XDCAM光碟可以应用在传统影带式的工作流程。
其录影机亦可作为随机存取磁盘机，以IEEE 1394及以太网等途径容易汇入录像到非线性编辑系统。
所以与过去使用影带的录影机系统比起来，进行非线性编辑更容易。
一.压缩方式XDCAM格式使用数种不同的压缩方式和储存格式。
虽然DVCAM及IMX独立型号有提供，很多标清XDCAM摄影机可简易切换IMX至DVCAM等格式。
IMX (MPEG IMX)IMX容许录影标清视讯，使用MPEG-2编码，位元率达30、40或50 Mbit/s。
MPEG IMX不使用暂时压缩，这可适合作剪接格式。
50 Mbit/s的品质在视觉上可和Digital Betacam比较，及常作电视制作用途，主要是电子新闻采集，因在实际上色彩分辨率（DigiBeta的10位元对IMX的8位元）和更低压缩比比Digital Betcam更好DVCAM (DV25)DVCAM使用标准DV编码，位元率高达25 Mbit/s，相容于大部分DV剪接系统。
XDCAM HD (XDCAM HD420, MPEG HD420)XDCAM HD支援多种品质模式。
HQ模式位元率可达35 Mbit/s，使用可变动位元率(VBR) MPEG-2长GOP式压缩。
可选的18 Mbit/s (VBR) 及25 Mbit/s (CBR)模式可增加录影时间，相对地减少视讯品质。

ZEISS XRM are specified on true spatial resolution, the most meaningful measurement of a microscope’s performance.Spatial resolution refers to the minimum separation at which you can resolve a feature pair with an imaging system. It is typically measured by imaging astandardized resolution target with progressively smaller line-space pairs. Spatial resolution accounts for critical characteristics such as X-ray source spot size, detector resolution, magnification geometry, and vibrational, electrical and thermal stability. Other terms such as “voxel,” “spot size,” "detail detectability," and “nominal resolution” do not provide you with an understanding of full system performance.› In Brief› The Advantages › The Applications › The System› Technology and Details › ServiceYour Insight into the Technology Behind ItAn Edge In ContrastYou require superior contrast capabilities to reveal details needed to visualize and quantify features. Xradia Versa deliver flexible, high contrast imaging for even your most challenging materials – low atomic number (low Z) materials, soft tissue, polymers, fossilized organisms encased in amber, and other materials of low contrast.Our comprehensive approach employs proprietary Enhanced Absorption ContrastDetectors that achieve superior contrast by maximizing collection of low energy photons while minimizing collection of contrast-reducing high energy photons. In addition, Tunable Propagation Phase Contrast measures the refraction of X-ray photons at material transitions to allow you to visualize features displaying little or no contrast during absorption imaging.Pear imaged with absorption contrast – no visibility of cell walls (left), and pear imaged with phase contrast, showing details ofcell walls in normal cells and stone cells (right).› In Brief› The Advantages› The Applications› The System› Technology and Details › ServiceTailored Precisely to Your Applications› The Advantages› The Applications› The System› Technology and Details› ServiceLarge flip chip (10x10x1 mm) imaged at high resolutionUnstained water in Ottawa sand, imaged in a 12.5 mm diameter aluminum tubeComposite material of polyurethane, EDPM, metal oxides and high melting explosiveMurine breast tissueZEISS Xradia 410 Versa at WorkNatural Resources Materials ResearchElectronicsLife Sciences125 µm5 mm0.7 mm1 mm› In Brief › The Advantages › The Applications › The System› Technology and Details › Service1211910768354Your Flexible Imaging Solution4 System Stability for Best Imaging • Granite base vibrational isolation • Thermal environment stabilization • Low noise detector• Proprietary stabilization mechanisms5 System Flexibility for Diverse Range of Sample Sizes• Variable scanning geometry • Tunable voxel sizes• Absorption contrast mode • Phase contrast mode• Wide Field Mode (WFM) for increased lateral tomography volume with 0.4X objective• Vertical Stitching for joining multiple tomographies vertically6 Autoloader Option• Maximize productivity by reducing user intervention • Programmable handling of up to 14 samples• Automated workflows for high volume, repetitive scanning7 Sample Stage• Ultra-high precision 8-degrees of freedom sample stage 15 kg sample mass capacity8 X-ray Filters • Single filter holder• Set of 12 filters included• Custom filters available by special order 9 In Situ and 4D Solutions• Resolution at a Distance (RaaD) enables superior in situ imaging • I ntegrated in situ recipe control for Deben stages • In situ interface kit option • Custom in situ flow interface kit by special order 10 Instrument Workstation• Power workstation with fast reconstruction • Single CUDA-based GPU • Multi-core CPU • 24” display monitor11 Software• Acquisition: Scout-and-Scan Control System • Reconstruction: XMReconstructor • Viewer: XM3DViewer• Compatible with wide range of 3D viewers and analysis software programs• ORS Visual SI for 3D visualization and analysis (optional)1 X-ray Microscope• ZEISS Xradia 410 Versa with Resolution at a Distance 2 Source Options• Light materials, closed reflection source (20 – 90 kV, maximum 8 W)• High energy, closed reflection source (40 – 150 kV, maximum 10 W)• High power, closed reflection source (40 – 150 kV, maximum 30 W)3 Contrast-optimized Detectors• Innovative dual-stage detector system with detector turret of multiple objectives at different magnifications with optimized scintillators for highest contrast• 2k x 2k pixel, noise suppressed charge-coupled detector› In Brief › The Advantages › The Applications › The System› Technology and Details › ServiceTechnical Specifications› In Brief› The Advantages› The Applications› The System› Technology and Details› ServiceBecause the ZEISS microscope system is one of your most important tools, we make sure it is always ready to perform.

索尼A7S科普性评测看S-Log
索尼A7S科普性评测看S-Log1曲线早已在专业产品中发挥作用前言：一台“不太正经”的相机，所以才有了这篇文章A7S的评测我们已经上线，详情请点击【全新CMOS极致高感索尼微单A7S详细评测】。
没错，高感无疑是它的绝对优势，但除去高感，1220万有效像素的全画幅CMOS相对于近2W的售价毫无亮点。
如果在网上搜索A7S，会发现大家谈论的焦点都是视频功能。
没错，索尼A7S给人的感觉更像是加错了天赋的微单，视频功能远强于拍照功能，所以一篇额外的视频功能解析会让您更好的了解这款产品。
曲线是A7S视频功能中最主要的优势，也是本篇评测的重点。
可以说曲线是一个隐藏在相机中，很少有人使用但可以改变视频色调、甚至提升画面质量的功能。
在专业视频领域，曲线早已发挥出不可替代的作用：让低成本的设备具备影视级的拍摄效果。
曲线对于普通摄影爱好者来说很陌生，但随着索尼在A7S中下放了专业摄像机的S-Log（曲线,细分名称S-Log2，以下简称S-Log）后我们老百姓也有机会接触到如此高大上的功能。
何为科普性评测？我不仅要测试A7S的视频效果到底好不好，还要告诉您到底什么是S-Log。
索尼ILCE-7S(单机) 产品综述|图片(501)|参数|报价|点评(24) ZOL商城价12480元专注数码服务到家去购买ZOL商城￥12480索尼A7S·S-Log是个相对新鲜的功能A7S三大主打优势：高感、超采样、S-Log，在测试高感以及超采样之前，笔者决定先对更陌生的S-Log进行测试，而且测试前我们必须先看一下使用S-Log拍出的效果。
左图为开启S-Log，右边为正常拍摄（A7S视频截图）开启S-Log后很明显画面变灰了，但有意思的是亮部细节和暗部细节都要优于没有使用S-Log所拍摄的。
也就是说开启S-Log以后可以大大提升画面宽容度，至于灰色的画面后期调整就OK了。
索尼F55拍摄的RAW格式视频截图“视频越灰越好”，这是一个90%正确的命题，另外10%涉及到很多算法问题笔者也无法解答。

索尼FDR-AX1 4K 手持摄像机说明书
Key FeaturesCapture 4K/60p video that far exceeds HD resolutionPlayback 4K content captured on the AX1 on a compatible 1 4K TV by simply connecting the two devices with supplied HDMI cable. Thanks to original Sony technology, Sony BRA VIA TVs especially bring out the full quality of 4K/60p recordings. Full HD monitors can also be used to enjoy this content by simply changing the menu HDMI output settings to 1920 x 1080.XA VC-S codec allows extended 4K/HD video recordingThe FDR-AX1 records 4K/HD movies in the XA VC-S format, which was developed for consumer usage based on the professional XA VC 4K/HD format. XA VC-S uses MPEG-4 A VC/H.264 Long GOP for video and linear PCM for audio compression, while saving files in an MP4 wrapper. The XA VC-S codec allows longer recording times within a given media capacity than XA VC, making 4K recording easier and more convenient.1/2.3” 8.3MP Exmor R ® CMOS image sensorSony’s unique Exmor R ® CMOS sensor is essential to the stunning image quality that the FDR-AX1 achieves. Its back-illuminated structure featuring wiring layers on the back of a photodiode (light receiving element) dramatically boosts low-light sensitivity for shooting better, more lifelike images even in dim lighting. Sony’s cutting-edge technology also makes the camera nimble at reading massive 4K data at 60 fps.Professional image processor for real-time 4K / 60 fps recordingAn extraordinary image processor, identical to those in 4K camcorders used by professionals, rapidly processes signals transmitted from the CMOS sensor and finalizes images. In processing the vast 4K data in real time at 60p, the processor achieves four times the resolution of the HD format. This processor not only features high-performance noise reduction technology for better image quality, it is also specifically tuned for the AX1 so it delivers image processing performance that accelerates the evolution of camcorders.Sony G-lens with 20X (31.5-630mm eq.) smooth servo zoomThe “G Lens” advances the Sony heritage of image processing innovation by redefining what an aspheric lens and special low-dispersion glass together can faithfully reproduce. Accordingly, the “G Lens” is specially tuned to capture qualities of definition and color that put these groundbreaking Handycam ® camcorders in a class of their own. In addition, the high-quality lens offers a broad zooming range from wide-angle to 20x optical zoom (31.5-630mm 35mm equivalent), enabling an amazing range of video expression.3 ND filters and 5 paint functions for expressive cinematic looksThe AX1 features three ND filters for adjusting the amount of light entering the image sensor from the lens. There are four filter settings: Off (Clear), ¼ filter, 1/16 filter and 1/64 filter. These filter settings give users the ability to adjust to light conditions, while maintaining desired shutter angle and aperture even on bright and sunny days. Six paint functions (white, offset white, gamma, detail, skin detail and matrix) can be combined and adjusted in the paint menu to create expressive movie styling and cinematic looks.Built-in mic w/2x additional Pro XLR jacks for external inputsIn addition to a high-performance internal microphone, the AX1 features two external XLR jacks for connecting external microphones that can also be used to record superior-quality balanced audio synchronized to the video. You can also mix audio from recordings made using the internal microphone and externally connected microphones, respectively.7x assignable buttons and 3x control rings (focus/iris/zoom)FDR-AX1Sony’s First 4K/60p Consumer Camcorder Tell your story in four times the resolution of Full HD with the 4K camera that’s made for everyone. Shoot with the breathtaking quality of XA VC-S 4K/60p and capture professional audio with XLR mic inputs. Even take direct, manual control with zoom, focus and iris rings, plus 7 assignable buttons. The groundbreaking power of 4K is ready to capture your imagination—experience it with Sony. Let the revolution begin.The AX1 was designed with two start/stop buttons (one on the side of the camera grip and another on the handle) for ease of use while shooting.The handle also features a zoom lever that enables convenient access while shooting from low angles.Seven assignable buttons can be programmed with functions that enable users to quickly access them without using menus. Assign functions to adjust to shooting conditions on the fly such as Marker, Zebra, Peaking, Focus Magnifier, Auto Exposure Level, Steadyshot, Color Bars, Rec Lamp [F], Rec Lamp [R].Two XQD card slots for high-speed 4K recording and playbackThe AX1 uses XQD media card for smooth, high-speed reading and writing of 4K video and features two XQD media slots.A relay recording feature makes it possible to lengthen recording by automatically switching between two or more media.The AX1 is compatible with following types of XQD media cards:XQD media card S-seriesXQD media card H-seriesXQD media card N-seriesView 4K 60P video on compatible BRA VIA® TVs w/supplied HDMI® cablePlayback 4K content captured on the FDR-AX1 on a 4K TV by simply connecting the two devices with supplied HDMI® cable.

ANALOG DEVICES AN-551 数据手册
a AN-551APPLICATION NOTE One Technology Way • P.O. Box 9106 • Norwood, MA 02062-9106 • 781/329-4700 • World Wide Web Site: Power Management of the ADV7172/ADV7173 Video EncoderINTRODUCTIONThis application note describes the different power op-erating modes of the ADV7172/ADV7173 and how the device should be configured or used in order to use power as efficiently as possible.THE THREE POWER OPERATING MODES AVAILABLE ON THE ADV7172/ADV7173The ADV7172/ADV7173 has three power operating modes:Normal Power Mode at 5 V or 3.3 VWhen all DACs are switched on, the current consumed is set by R SET1 for the large DACs (DAC A, B, C), R SET2 for the small DACs (DAC D, E, F) and V REF. See Tables I and II for the different current settings.Low Power ModeLow Power Mode is only available at an operating volt-age of 5 V. It only takes effect when the large DACs (A, B, C) are switched on. This facility will reduce the average current consumed by each large DAC (which is powered on) by approximately 40%.How Does Low Power Mode Work?Considering each DAC as a group of current sources, when any current source has a DAC code of zero (i.e., off), the DAC current is switched to ground and current is con-sumed unnecessarily. If the current source is then switched off instead of being switched to ground, the current consumed can be reduced by approximately 40%.Sleep ModeSleep Mode is available at 5 V and 3.3 V operation. The current consumed by the ADV7172/ADV7173 is typi-cally less than 20 µA. This mode can be used while powering up or while configuring the registers.Two M ode Registers allow control over Sleep M ode: Mode Register 2, “Sleep Mode Control” and Mode Reg-ister 6, “Power Up Sleep M ode.” In M ode Register 2, Sleep Mode is enabled when the according bit (MR27)“Sleep M ode Control” is set to Logic 1 and disabled when it is set to Logic 0.When enabled, the current consumption of the ADV7172/ADV7173 is typically less than 20 µA. If the de-vice is set to operate in Sleep Mode and if Sleep Mode is disabled in setting the according bit (MR27) to Logic 0,the device will come out of Sleep Mode and resume nor-mal operation.Also, if the device is set to operate in Sleep Mode and a reset is applied, the device will come out of Sleep Mode and resume normal operation. This mode will only oper-ate when Mode Register 6, “Power-Up Sleep Mode” is disabled (set to Logic 1), otherwise Sleep Mode is con-trolled by the PAL_NTSC and SCRESET/RTC pin.Note that the I2C interface still operates in Sleep Mode.Mode Register 6M R60 “Power-Up in Sleep M ode” allows the user to control powering up the device in Sleep Mode to facili-tate low power consumption before the I2C is initialized. The device will power up in Sleep Mode if the SCRESET/ RTC pin and the NTSC_PAL pin are tied high and the “Power-Up Sleep M ode” control (M R60) is set to En-abled (set to a Logic 0). This bit is always set to 0 after powering up or after applying a reset.When “Power-Up Sleep M ode” is disabled or set to a Logic 1, Sleep Mode control passes to Mode Register 2,“Sleep Mode Enable” control.THERE ARE SEVERAL METHODS TO REDUCE POWER CONSUMPTION OF THE ADV7172/ADV71731. Operating Voltage: 5 V Low Power Mode2. Operating Voltage:3.3 V3. Sleep Mode4. Turn Off Unused DACs5. External Buffering6. TV AutodetectOperating Voltage: 5 V Low Power ModeMode Register 1, Bit 6, “Low Power Mode Control” al-lows the Low Power Mode to be selected. Note, that Low Power Mode is only available at 5 V operation.Low Power Mode will reduce the average current con-sumed by each DAC by approximately 40%.In normal mode the current consumed is set by R SET1, R SET2 and V REF. In Low Power M ode this set current is reduced by approximately 40%. For each DAC the rela-tionship between R SET1/V REF and R SET2/V REF and the out-put current is unchanged by this.–2–AN-551Operating Voltage: 3.3 VIdeal or optimum performance is achieved when the de-vice is operated at 3.3 V and DAC A, B, C (large DACs) are set to an output current of:I OUT = 18 mAwhereR SET 1 = 300 ΩR SET 2 = 600 ΩR LOAD = 75 Ω (Single Terminated Load)Sleep ModeIs available at 5 V and 3.3 V operation.The current consumption of the ADV7172/ADV7173 is typically less than 20 µA.As mentioned before, this mode can be used while powering up the device or while configuring the regis-ters. See Sleep Mode section for details on how to oper-ate Sleep Mode.Turn Off Unused DACsIt is recommended that whenever a DAC is not used, it should be switched off.This is done in Mode Register 1, where each DAC can be individually powered off. Refer to Table I and Table II for further details.External BufferingExternal buffering is another way to reduce power con-sumption. Whereas DAC D, E, F (small DACs) always need buffering, buffering on DACs A, B, C is optional (when DAC D, E, F are not used). In the shown configura-tion the DACs A, B, C are running at 18 mA, which is half of their full current capability. This allows a reduction in power dissipation by 50% in the current that these DACs consume.600V CVBSGCHROMARB300Figure 1.Output DAC Buffering ConfigurationThe resistors are given the following values:R SET1 = 300 ΩR SET2 = 600 ΩR LOAD = 75 Ω Single TerminatedIt is further recommended to use this configuration at an operating voltage of 3.3 V. This allows optimum DAC performance and adds extra isolation on the video outputs.OUTPUT TOOUTPUT FILTER/TV MONITORINPUTFigure 2.Recommended DAC Output Buffer Using an Op AmpTV AutodetectThis feature allows the user to determine whether or not the DACs are correctly terminated. This facility is avail-able for DACs A, B, C since unconnected (not used)DACs increase power consumption.Mode Register 6 allows automatic detection of untermi-nated DACs:1.The “DAC Termination Mode” control allows to select between correct 75 Ω or 150 Ω termination.Note that double terminated 75 Ω becomes 37.5 Ω (i.e.,75 Ω on the DAC end and 75 Ω on the TV end) and 150 Ωbecomes 75 Ω. For this reason the Autodetect facility cannot operate if the large DACs are buffered, since buffering results in a fixed termination, regardless if cor-rectly or incorrectly terminated at the buffer output.Mode Register 6 “DAC Termination Mode” control (Bit 4) allows the user to select between two Autodetect Termination modes:1 × Mode = 75 Ω Termination (Single-Terminated)2 × Mode = 150 Ω Termination (Single-Terminated)Mode Register 6 “Comp Autodetect Mode” control (Bit 3) and “Luma Autodetect” control (Bit 2) allow the choice between two functions:Mode0Correct termination of the DAC is checked and indicated with the according Status bit set to “1” or when using the Evaluation Software, Mode Register 6 (Autodetect Status) a green button indicates correct termination.If not correctly terminated, the user has the choice to power down the DAC or not. This can be done by using Mode Register 1.AN-551Mode1Correct termination of the DAC is checked and indicated with the according Status bit set to “1” or when using the Evaluation Software, M ode Register 6 (Autodetect Status) a green button indicates correct termination.If not correctly terminated, the DAC is automatically powered down.Correct termination is checked at intervals of one frame to decide whether or not the DACs are to be powered down.SETTINGS FOR R SET1, R SET2, R LOADOperating Voltage: 5 V/Normal ModeThe values for R SET1 and R SET2 determine what current will be consumed by each DAC and, therefore, what power will be consumed.The current consumed is calculated as:I OUT = (V REF×K )/R SETV OUT = I OUT×R LOADV REF = 1.235 VK = 4.2146DAC A, B, C (Large DACs)R SET2 is used for the small DACs and has no effect on the output current of the large DACs.I OUT = 34.7 mA R SET1 = 150 ΩR LOAD = 75 Ω (Single-Terminated)I OUT = 5 mA R SET1 = 1041 ΩR LOAD = 262.5 Ω(Buffered, Scaled Output Load)See Table I and Table II for further details.DAC D, E, F (Small DACs)R SET1 is used for the large DACs and has no effect on the output current of the small DACs.I OUT = 8.66 mA R SET2 = 600 ΩR LOAD = 150 ΩI OUT = 5 mA R SET2 = 1041 ΩR LOAD = 262.5 Ω(Buffered, Scaled Output Load)See Table I and Table II for further detailsOperating Voltage: 3.3 V/Normal ModeThe same settings for R SET1 and R SET2 apply for 3.3 V op-eration as shown above for 5 V operation.3.3 V operation will reduce the power dissipation due tothe V × I = P formula, i.e., the current is unchanged whilethe voltage decreases from 5 V to 3.3 V.JUNCTION TEMPERATUREIt is important to keep in mind that at no time the maxi-mum junction temperature of 110°C should be exceeded:Junction Temperature = [V AA(Σ of

Cine EI模式原理解析与应用
Cine EI 模式原理解析与应用文/邯郸广播电视台 殷唯杰摘要 ：随着索尼新款摄像机型FX9V的推出，它的Cine EI模式重新成为业界热议的话题，与普通摄像机的拍摄模式不同，在此模式下，索尼运用S-log曲线技术和S-Gamut色域范围概念使高质量画面的拍摄成为可能。
本文将以FS7机型为例，从宽容度的概念入手，详细对比分析Cine EI模式下几种S-log曲线的技术特征和成像差别、各种S-Gamut色域值的记录范围、曝光指数的概念及其如何影响画面质量，在Cine EI模式下套Mlut如何正确控制曝光，以及实际应用中如何正确使用这一模式进行详细解析。
关键词 ：Cine EI；宽容度；S-log曲线；曝光指数基于优质的画面质感、亲民的价位和巨大的后期调色空间，现在越来越多的电视机构、媒体公司都在用索尼PXW系列的F55\F5\F7摄像机作为“主打机”，它们也被称为入门级电影机。
可以说，这些机型之所以广受追捧，正是基于其拥有的Cine EI模式，在这种模式下使得高品质、电影质感的图像拍摄成为可能，它被大量使用于纪录片、宣传片、微电影、高品质广告片乃至影视剧的拍摄。
近期随着新款机型FX9V的推出，索尼的Cine EI模式又重新回到讨论的焦点，虽然使用者芸芸，但真正懂得其中原理者寥寥，本文将以索尼的FS7为例对Cine EI模式工作原理和使用方式进行详细解析。
1. 详解Cine EI模式1.1 什么是Cine EI 模式索尼FS7为用户提供了两种拍摄模式，分别是自定义模式和Cine EI模式。
自定义模式主要用于即拍即用、不需要过多后期处理的普通拍摄，即我们经常使用的摄像机方式。
Cine EI模式又称电影风格摄像模式，它模拟胶片电影摄影机的工作方式，拍摄出看起来低对比度但具有更广色域和高宽容度伽马曲线的画面。
在此种模式下白平衡、亮度增益均无法调整，但可以调整曝光指数，它是拍摄高质量画面的基础。
使用此种模式拍摄分为两项工作，前期拍摄和后期调色，在前期拍摄中将包含丰富信息的画面记录下来，后期再通过增加对比度及饱和度等多种调色方式还原丰富色彩及层次的画面。
电视节目制作
第一章电视节目制作概述第一节电视节目制作手段一.实况直播实况直播就是在摄取图像、声音的同时就进行广播，它是将制作和广播这两个过程合二为一，或者说同步进行。
1.现场直播2.演播室直播实况直播的特点: 现场性和即时性强。
二.电视影片制作用电影摄影系统摄制，再转成电视的制作手段。
特点：图像质量高，无制式困扰，便于节目交换。
三.录像制作使用磁带、光盘、磁卡、硬盘、无线录制系统制作。
特点：节省开支，手段灵活。
第二节电视节目制作方式制作手段是指达到电视广播的目的而采用的总的方法措施。
制做方式实际是指使用录像手段，直播手段中的几种制作方式，着重于所使用的设备系统及有关的软件系统。
这些方式的特点是必需通过摄像机制作。
一.ENG方式ENG[Electronic News Gathering ] 即“电子新闻采集”，使用便携式的摄像、录像设备来采集电视新闻。
二.EFP方式EFP(Electronic Field Production)即“电子现场制作”,是对一整套适用于台外作业的电视设备的统称。
三.ESP方式ESP(Electronic Studio Production)即“电子演播室制作”，它主要是指演播室录像制作。
