The Digiflash is made to exacting GOSSEN calibration standards for high precision measure-ments. The trendy styling and logical func-tioning make it easy and comfortable to operate. Key features:•Incident and reflected light meas. mode •Measuring of ambient and flash light •µP controlled•Digital LCD read-out in the display in 1/3 stop increments•Contrast readout in 1/3 EV steps •Storage of the measuring results •Indication of all suitable combinations of shutter speeds and f-stops•Signal "range over" or "range under"•Automatic battery check•Countdown timer for long exposures •Function Watch/Alarm clock •Measuring temperatures1The functioning of the Digiflash 1.1Preparation and self-testBatteryThe Digiflash is powered by a 3 V Lithium battery, type CR 2032. When the battery is running low, BAT appears in the display.–The battery should be replaced as soon as possible. When BAT is shown alone in the display, the battery will need to be replaced before further measurements are possible.–To replace the battery, pull out the battery compartment located under the eyelet for the carrying cord.–Remove the old battery and insert the new one. Observe the "+" and "–" polarity!–Close the battery compartment Attention! The Digiflash is provided with a battery memory of 10 seconds. If the battery is removed briefly or replaced only within those ten seconds, the values stored in memory will be maintained. Otherwise changing the battery or pressing one of the buttons will cancel all the individually stored values.Self-TestAfter the new battery has been inserted, the microcomputer will carry out a self-test. Every display segment appears in the display panel. The self-test takes 10 sec-onds. It can be interrupted before by press-ing any button.After the self-test, the standard settings willbe shown as set by the factory.Standard settingsISO100/21°COR0ambient EV8 t1/125flash EV121.2Incident light and reflected light Incident light methodFor the incident mode, the diffusor is to be shifted to the left and placed in front of the measuring aperture. Taking measurements using the incident light mode in particular produces in most cases perfectly exposed shots. In this mode, the DF measures from the subject towards the camera. This guar-antees that the tone quality of the picture is equivalent to that of the subject. This is es-pecially important for very bright or dark subjects. Even under very difficult lighting conditions, as e.g. with subjects which have a lot of contrast, the incident light mode is a more reliable way of producing well ex-posed pictures.Reflected light methodFor the reflected mode, the diffuser must be shifted to the right. Care must be taken, that the light sensor is entirely free.The measurement is taken from the position of the camera towards the subject. In this method, only the light reflected from the subject is detected by the meter. Therefore, the measuring values always depend on the reflection capacity of the subject. As a result of this, bright subjects are reproduced darker and therefore not properly exposed. Consequently, this mode is conveniently used, when the suject does not show too high contrasts between bright and dark areas.1.3Duration of read-out in displayThe Digiflash will always display the last function used. The meter does not automatically switch off, as the power consumption is extremely low.2Functions of the Digiflash Press the function button for selecting the individual functions of the Digiflash.Each time the button is pushed, the next function will be activated.The display panel will show the functions in the following sequence:•Ambient light•Flash light•Timer•Watch•Alarm clock•TemperatureThe next function will only be activated after the Function button has been released. When the Function button is kept pressed down for more than two seconds, the settings of that function are displayed and can be adjusted as desired.2.1Setting the film speed–Select the function "Exposure ambient light" and hold down the function button until the OK-signal sounds. The display will show ISO, blinking.–Use the measuring key M to select the desired film speed.When holding the key M pressed down, the film speed will automatically beincreased. When getting close to thedesired ISO value, release the key Mand set the desired film speed by pushing the key in individual steps.Each time you push the key, the filmspeed is increased by a 1/3 stop.–Confirm the speed you selected by pushing the Function button until the OK-signal sounds and the Digiflash re-turns to the function "Exposure ambient light". The film speed is shown in the up-per right corner of the display.If the film speed is changed, the measure-ment read-out stored in the memory will be immediately converted to the new ISO settings.The film speed selected will stay storedin memory until it is changed in the way described above.The film speed selected will be valid both for ambient and flash light.2.2Exposure measuring ambient light –Use the Function button to select the function …Exposure measuring ambient light“.–The measurement is taken by briefly pressing down the measuring key M.2.2.1Read-out of the values measured The EV value measured will appear in the display. The values will be indicated in1/3 - stop increments by one dot, the 2/3 - stop increments by two dots.–Transfer that EV value from the display to the setting window in the calculator rings and place it precisely under the red indi-cator line.–All the suitable combinations of aperture (f-stops) - t (shutter speeds) can now be seen at the upper part of the circular scales (see previous example).2.3Flash measurement2.3.1Setting the sync speed(measuring time)–Press the function button for selecting the function …flash measurement“. A small stroke in front of the sync time will appear in the display to signal …flash metering“.–Keep the function button pressed down until the ok signal sounds. The display will now show the sync speed blinking.–Use the measuring key to input the desi-red sync speed, in the range of 1 sec to1/500 sec. and confirm by pressing the function button.2.3.2Measuring–Push the measuring key.The Digiflash is ready to measure for30sec, as long as …F“in the display is on.–Trigger the flash.–Transfer the value measured from the display to the window in the printed sca-les above and set it precisely under the red indicator line.–Read the f/stop in the upper part of the scale opposite the sync speed you had preselected (for 1/90 read between 1/60 and 1/125).2.3.3Fill-in FlashesYou will find the right combination in two steps:First you take a reading of the background in the function …ambient light“. Transfer the EV value from the display to the setting win-dow above. Then set the corresponding combined shutter speed and f/stop to your camera, while taking care that the shutter speed must be equal to the flash sync speed.In the second step, you determine the fill-in flash by measuring the flash in the incident mode. From the shadow area of the subject you direct the Digiflash towards the came-ra in such a way that the meter will only re-ceive the fill-in flash and the stray light, but definitely not the main light source.The resulting EV value should be lower by 1to 2 stops than the EV value for the ambi-ent light. If not, adjust the power of the flash unit or change the distance to get the desi-red EV value.2.4Taking a measurementoutside the measuring rangeThe Digiflash will not produce any useable readings outside its measuring range:in the display Eu (too dark) or E n (too bright) will appear. 2.5Contrast measurements–Use the Function button to select the function "Exposure ambient light".–Keep the measuring key M pressed down and the meter will switch over to contrast measurement. Continue holding downthe key to measure various other areas in the subject. In the display, the difference between the individual results of theadditional measurements and the firstmeasuring value will be indicated in EV.A new metering will be made approx.2times a second.After you have released the measuring key M, the value of the first exposure measure-ment will reappear.2.6Setting correction valuesIn order to deliberately change the exposure of your photos, you may adjust the factory calibration.–Remove the battery from the Digiflash and press one of the buttons (battery memory will be deactivated). Put the bat-tery back in the compartment. The meter will then make the self-test.–During this test, keep the measuring key and also the function button pressed down until the accoustic signal sounds. Release the key to enter the CORRECTION function.Use the measuring key M to enter or change the correction value.Press the function button again and hold it down until the OK signal sounds to return the meter to the normal measuring func-tions.The EV in the display will blink to remind you that the standard factory calibration has been changed. Input of the correction in1/3-stops in the range of ± 3 EV.For cancelling the correction value, remove the battery from the compartment and then put it back again.In case of over-exposure a positive correction, in case of under-exposurea negative correction value should be set.2.7Function TIMERA timer function is provided in the Digiflash, useful for long exposure or other timings ranging from one second to thirty minutes.–Use the function button to select the function TIMER and hold it down until the OK-signal sounds. The display shows the last value used. The read-out will show the "minutes" and will flash to allow the countdown timer to be adjusted.–Use the key M to enter the desired time in minutes.–Confirm by pushing the function button. The read-out "seconds" in the display will flash. –Enter the "seconds" of the desired length of time. Confirm by pressing and holding the function button until the OK-signal will sound. The timer will now be in the Start/ Stop function.–Push the key M to start the timer.The display will show the remaining time of the count-down. In addition to that,during the last 10 seconds of the count-down, interrupted signals can be heard.At the end of the set time, a continuedsignal will sound.–To pause the count-down, push the measuring key; pressing it again will restart the count-down.The timer will work in the background so that you can use other measurements.2.8Watch/Alarm clockWATCH – Setting the time–Use the function button to select the function WATCH and hold the key down until the OK-signal will sound.12/24 will flash.–With the function button select either 12hours (AM/PM) – 24hour display.–Confirm with the function button.The read-out "hours" will flash.–Use the key M to set the hours and confirm with the function button.The read-out "minutes" in the display will flash.–Use the key M for setting the minutes. To confirm settings hold down the function button until the OK-signal is heard. ALARM CLOCK–Use function button to enter the function "ALARM CLOCK" and hold it presseddown until the OK-signal will sound.The time of the alarm clock is set in the same way as the watch.–Hold the function button until the OK-signal sounds.–The alarm is activated or deactivated with the measuring button.–When the alarm is activated it is shown in the display with a bell symbol.–When the alarm is sounded it will soundeach second for 1 min. It can be stopped by pressing either the measuring key orthe function button.2.9Measuring temperatures–Use the function button to select the function TEMPERATURE and hold the button pressed down until the OK-signal sounds. To change between °C or °F read-outs, press and hold the function button until the display changes.The Digiflash will indicate the actual ambi-ent temperature. The temperature probe is incorporated in the meter housing.As a result, the temperature measurement may be affected if you are holding the meter in your hand. If you attach the Digiflash with the clip to your camera, these errors can be avoided.2.9.1Min./Max. temperaturesWhen repeatedly pressing the measuring key, the minimum (Lo) and maximum (Hi) temperature values will be indicated. The minimum and maximum values indicated are those that have been measured since the last cancellation operation.The min. and max. temperature values stored in memory can be cancelled by pressing the measuring key until the OK-signal sounds. The temp. measurements are repeated automatically every two min. providing always the actual values. These min. and max. temp. values will make it pos-sible for you to check, whether your films may have been exposed to excessive high temperatures and have been damaged.3Service and repairsIn the event that your Digiflash is not work-ing to your complete satisfaction, please send it to:GOSSEN Foto- und Lichtmeßtechnik GmbH Thomas-Mann-Str. 16-20D - 90471 Nürnbergor to the GOSSEN agency in your country.4Technical dataExposure meterMeasuring modes Ambient lightFlash light (non cord)Incident light methodReflected lightmethodContrast measurem.

测光表介绍和使用(为摄影棚准备)
测光表介绍和使用(为摄影棚准备)测光表是一种用来测量光的强度的仪器。
在摄影中测光表被用来确定适当的曝光时间。
在胶片感光度和快门速度已知的情况下测光表给出获得最佳曝光的光圈值。
测光表也被用来做照明来控制照明的亮度，或者被用作手持的仪器来确保光强符合一定的要求。
测光表-作用现代相机中的测光系统已经十分发达，为什么许多摄影家还要使用手持的、离开相机而独立的测光表呢？因为：1、中片幅以上的相机很少有性能完善的测光系统，较大片幅的相机大都没有测光系统。
2、比起相机内测光系统来，手持测光表可以有更灵敏、更精确的测光性能，例如可以测量到一档光圈的1/10，对于弱光更加灵敏。
测量角度也可以达到很小，例如1度，这也是常见的具有“点测光功能”的相机达不到的。
3、在有些场合，如风光、静物、产品、模特摄影中，移动相机去测光很不方便，而把相机留在三脚架上，手持测光表去测量、思考、判断要从容得多。
4、相机内测光系统只能测量反射光，而手持测光表还可以具有测量入射光和闪光的功能。
测光表-使用方法测光表是用来测量被摄体的反射光的亮度或光源照度的一种仪器。
根据感光片的感光度与摄影者创作意图的需要，用它来测量光线的亮度，确定光圈、快门速度的曝光组合。
常见测光表的使用大体上有五种方法：1、机位测光法机位测光法是在景物亮度分布较均匀的情况下，测光表同位于照相机取景方向对被摄体进行测光，所获得的亮度值是景物反射光的平均光值，依据这个亮度值来确定曝光，能较好地表现整个画面的影调。
此法常用于拍摄远景或全景风光片。
采用机位测光法，应注意景物亮度的分布，使测量范围内的景物明暗有适当的比例。
测光表的感应窗对应着主体物，避开(或少包括)亮度很亮的天空或反光很强的水面，否则测光表指数偏高，而实际曝光偏低，容易造成底片曝光不足。
在拍摄逆光景物时，要防止阳光直接射向测光表，不然也会因测光不准而造成曝光不足。
即使阳光没有直接射向测光表，也应按逆光景物的反差及暗部面积大小，酌情增加半级到一级曝光量。

测光表的使用方法
测光表的使用方法测光表的使用方法摄影学习资料 2010-02-24 23:59:54 阅读844 评论0 字号：大中小订阅本文引用自艺耕《【摄影】测光表的使用方法》引用艺耕的【摄影】测光表的使用方法有经验的摄影师在拍摄照片时可较准确地估计出自然光条件下的曝光时间，即使有些出入，只要曝光量在胶片的宽容度范围内，也能冲洗出合格的照片。
而对于追求高画质的摄影者来说，估计曝光难以满足准确曝光的需求。
对于大多数摄影者往往很难准确估计变幻莫测的自然光，尤其是照明情况特殊时，如一天的早晨和傍晚、夜间、室内、灯光下等。
因此，这时就需要使用测光表来确定被摄体准确的曝光量。
一、测光表的分类与特点测光表是用于准确测定被摄体所需曝光量的仪器。
根据其是自成一体还是与相机结合在一起分为手持测光表和机内测光表两类。
①手持测光表：自成一体，测光时需要手持进行测量。
手持测光表根据其测量光源的不同分为普通测光表（测量自然光和白炽灯等持续发光光源的亮度，图一A）和闪光测光表（测量闪光灯等瞬间发光光源的亮度，图一B）。
此外，手持测光表根据测光方式不同又分为入射式测光表和反射式测光表。
前者是测量投射光的照度，后者是测量被摄对象反射光的亮度。
现在设计的测光表兼有测量反射光和入射光两种功能。
其测光部位有一乳白罩，不加乳白罩时，测反射光亮度，加乳白罩后测入射光照度。
闪光测光表：有两种类型，一种是有一导线与闪灯连接，按动按钮后可触发闪光灯，同时测定闪光亮度，并将曝光组合值定格在液晶屏上。
另一种是没有导线与闪灯连接，使用时先打开测光表，然后手动触发闪光，便可测定闪光灯亮度及曝光EV 值。
现在的新式手持式测光表将测持续光源与测闪光光源亮度的功能合二为一，同一只测光表，既能测持续光源亮度，又能测闪光光源亮度。
②机内测光表：这是将测光表设计在相机内部的一种形式。
由于测光表设置在相机内，就免去了单独携带测光表的麻烦，而且可在取景同时进行测光，大大提高了测光效率。

测光表说明书
左到右：1、保护套2上、安装架安装在机器上的样子3、主机4、测光棒1、测光窗？推测的，测光时手挡住有反应2、红外接收窗？共有四个正面两个，上面还有两个，好像是闪灯红外触发的接收器3、指示灯？没亮过，不知道是干嘛的4、power 电源？反正关机状态按它无法开机，开机时无法关机。
按了一通必须和“+”“-”键配合使用5、ISO 这个理解，是设定胶片感光度，可设置范围是3-4000，配合“+”“-”键使用6、7 - + + - 设定参数使用，配合其它功能键8、ON 开机9、ANALYSE analyse 分析？分析？10、MEAN mean ？不懂11、MULTI multi 多点？12 侧按键上摸索了好像是清除13 侧按键下测光键14 闪光同步插口测闪灯时接收触发信号的接口15、外接测光棒接口16、调节空好像是微调参数用的17、电池仓装9V叠层电池18、锁定扳手19、安装的关键是图中所示的安装架18锁定扳手对面的安装卡19注意看后架侧面的安装槽，安装槽的上端有一扩大到空位，松开锁定即可插入，插入槽内后滑入下端然后锁定即可。
这时可把测光表侧面的槽位对准安装架的卡口滑入，为方便拍摄，是手持机器拍的示意图。
测光后背和fcm的配合1、安装孔，2、测光棒锁紧扳手（松开位置），3、测光棒（工作位置），4、测光表（装在前组上，与测光后组安装孔相同高度）；试装了一下，感觉测光后背的安装孔应不是设计安装测光表的，因为安装在1的位置时会出现使用问题：1、安装孔的位置太高，测光表将挡住2测光棒锁紧扳手的操作，无法松开；2、测光棒的安装架因测光后背的凸起，将无法调节角度；3、测光棒测光工作位置较高时将与测光表发生碰撞；最终感觉最合适的位置应该是在前组上。
ANALYSE 这个在外部光线OK 的情况下，也就是机器同时测到外部背景光和闪光的时候，如果按ANALYSE 会依次显示总量，环境光的量，闪光的量。
对于分析环境光的影响有用。
如何在摄影中使用测光表
如何在摄影中使用测光表摄影艺术家调色板中的关键工具之一是测光表。
这个必不可少的项目为您提供准确的照明信息，以便您可以正确设置曝光（可能是+1.5档曝光过度或-2档曝光不足；这都是必须严格控制的创意选择，以获得艺术性和您正在寻求的审美品质）。
由于您想精确测量特定场景的亮度，因此您需要了解如何正确地进行测量。
相机内的计算机仪表可以并且将会在各种照明情况下（黑色过多或白色过多）被欺骗。
手持测光表将缓解与相机测光相关的问题，并让您更好地控制曝光。
1、什么是手持式照度计？手持式光度计是一种通过对光强度作出反应的光电池来测量入射光（或环境光）和反射光（与相机的内置仪表测量的光类型相同的光）的设备.您所做的就是设置ISO（在某些情况下还设置快门速度），然后您会获得光圈值或英尺烛光（在某些旧型号中）的读数，以便您可以调整相机以获得精确和理想的曝光。
2、这个怎么运作手持式测光表与相机中的TTL测光表或点测光表的工作方式不同，尽管两种类型的测光表都测量反射光。
HHLM可以测量落在物体上的光（入射光）或从物体反射的光。
HHLM的视野非常窄（有时只有1度），这将使您能够获得最准确的光读数。
即使将TTL测光表设置为Spot （3到5度之间），您也无法在TTL测光表上获得那么窄的读数。
在某些类型的HHLM上，按住按钮将提供连续曝光，因此您可以看到光线如何从一个地方变化到另一个地方-即使在几英寸内。
在工作室中设想复杂的灯光方案时，您可能需要如此准确，3、如何使用手持式照度计手持式测光表上有两个附件，一个是平盘，另一个是半球。
平盘用于读取反射光。
为此，您只需将圆盘滑入并将计量单元直接朝向您想要读数的物体。
半球用于测量入射光。
您将测光单元上的半球滑动并将测光表放在拍摄对象的前面，这样光线就会像照在拍摄对象上一样落在球体上。
如果可以，请确保半球指向相机镜头……这样您就可以更好地了解相机的图像传感器将要记录的内容，而不仅仅是一般的光线读数。

These precision components eliminate the need for daily internal self-calibration to compensate for drift when less-precise components are used. Autozeroing also becomes unnecessary because the ampli-fier offsets are ultra-stable. The 8588A achieves an exceptional 8.5-digit resolution reading in one second, two times shorter than the next best in class, which amounts to considerable productivity improvements.The 8588A is easy and intui-tive to use.

第五节 校准你的测光表
第五节校准你的测光表象我这样的摄影师都趋向于相信，越昂贵的相机就会越精确。
有时候我觉得我们应该信任Nikon，相信他们已经把F5相机的ISO值刻在了正确的位置上，以使每一张照片都能使用精确的ISO设置。
因为只有当ISO值设置正确时，从测光表才能得正确的测光读数，无论是相机内置的TTL测光表，还是最昂贵的手持式测光表。
大多数新型号的相机，尤其是最近5年里推出的相机，都可以提供非常精确的ISO设置，一般误差在标记值的1/3挡范围以内。
然而，比较旧的型号的相机可能会有不同的误差范围，有时候误差可能会有一挡或两挡之多。
无论你的相机有多新，我都建议你使用你的测光表来校准一下ISO设置，以便确定ISO值能被设置到正确的位置。
首先，挑选一个你认为是中等色调的被摄物体，它必须没有非常浅或非常深色的区域。
（请记住：“中等色调”意味着介于深和浅色之间的中间色调：中间绿色、中间蓝色、中间褐色、中间红色等等。
不要去问其他人，你选择的被摄物是否是中间色调的。
因为你们的标准是毫不相关的，他拍他的照片，你拍你的。
）不要使用灰卡进行这个测试。
灰卡是为室内使用而设计的，当在户外使用时，会产生比较亮的反光而使测光表读数偏大。
事实上，我只建议把灰卡作为视觉的参考。
找一个与你在野外摄影时的拍摄对象相近的被摄物作为测试对象就可以了。
在整个测试过程中，不要改变光照条件。
如果一定需要的话，你也可以在室内用灯光照明进行测试，但我强烈建议你等到一个多云的晴天，在户外自然光照的条件下进行这个测试。
毕竟，那是你进行摄影的真实条件。
把你的相机架在三脚架上，并调整镜头焦距，使镜头里尽可能只看到你选择的被摄物体，而没有其他多余的东西，并锁定三脚架和云台。
可以使用任何镜头进行测试，因为我们只想测试相机内置测光表，而不是镜头。
在相机里装一个中等速度的反转片（不能使用负片进行这个测试），并把机身测光表的ISO值设置为对应的读数。
不要使用胶卷上的DX速度标记，而是手动设置ISO值。
