数码摄影之闪光灯应用技巧完全宝典（Digital photography flash complete collection of application skills）ForewordToday, digital camera A new force suddenly rises. greatly change our way of photography, beyond imagination powerful enough to inspire each user shooting desire, as a game player, how to make full use of the advantages of digital camera, to enhance the quality of the photos? The author believes that the equipment itself is just one aspect, more important is the shooting skills, reasonable and correct use of optical and photographic knowledge mining equipment, their potential, while the digital camera is just one of the most easy to use, can not do the cost of test equipment. Photography techniques can be broad and profound, not in two words or three clear, this article from the flash point of view, especially for the digital camera, to explain the practice of digital photography, also hope to display slight skill before an expert, the right to do something!Basics of flash technologyWhen it comes to flash, you may find it easy to use it at night. This is only part of it, in fact, the flash is an auxiliary tool use is very extensive, it is a photographic light source, when shooting, natural light environment (sunlight) or artificial light (light) is insufficient when the flash is made up of motor source of this problem. Despite the many kinds of types of flash, this paper refers to the single most common, various cameras have built-in flash one million times, it through the energystorage capacitor and the coil, in an instant release and a pressure sensor, a pulse excited inert gas source, thereby obtaining the instantaneous power of strong.Because the flash effect time is very short, generally speaking, the camera's shutter speed has been unable to adjust the flux effect, but for most digital cameras, the response speed of light without film, so don't even need to adjust the luminous flux, the light is not enough in the occasion, as long as the choice of the automatic entry into the flash mode or camera mode, then the shutter speed will automatically speed up to a relatively short value.This usually does not matter, but when the ambient light is sufficient, a flash is accidentally enabled during close shooting, and overexposure occurs. On the other hand, if the ambient light is very dark, an excessive shutter speed will make the flash dark beyond the effective range.To understand the characteristics of different reflective surface can better use the flash, because different objects have different reflection of light scattering ability, which is equivalent to a flash point light source, if the object is, or near the glass, marble, circuit board such as flat and smooth surface in the picture will be formed one of the highlights, the overall effect of failure. The way to avoid the glare is to change the lens angle, from side to side, so that the reflection of the flash is reflected from the other side without reflecting back.Standard version of flash technology - built in flashtechniquesReasonably set up and pay attention to checking the flash mode of digital cameraAll types of digital cameras, usually built with flash, and many models can also be connected to flash, so the digital camera will have a flash mode settings,Usually includes at least 3 basic modes: automatic, flash, flash, and most of the camera plus 1-2 special modes: "redeye, slow" one or all in the mode of operation, there is usually one of the keys can be controlled, with a few models of menu selection patterns and carefully check before use. In addition, the digital camera has a sleep mode, when from sleep wake up or shut down again after the boot, the flash mode may change, different models have different default mode, can not remember the last good state, some models will occur even after flash switch the "Browse / shooting" status the change of one of the problems most often make is to press the shutter after suddenly found the wrong way to flash again, so we must pay attention to check before shooting.Need to consider the occasion of using flashThe following general occasions is to use flash, unless there is behind the "disabled" said that the scene in 1, otherwise don't hesitate no light or dim light when shooting objects lack of brightness, such as night night portrait2 backlight, backlight shooting, shooting object andbackground luminance contrast time. For example, when the sun shines from behind the person, without a flash, the person will be very dark.3 when there are luminous objects and non luminous objects at the same time, for example, the TV screen, if you do not use flash, you can only see the screen picture, while the TV shell is black.4 when the brightness of the object is uneven in different parts of the object, the brightness of the object can be uniform by using flash.Do not use flash occasionsThe following situations should normally be considered to turn off the flash1 beyond the range of the flash and can not enter the effective range by adjusting the distance. During the day is generally not more than2 meters, at night do not exceed3 meters, to have good results, or else do not use the same, there will be no ideal results, some cameras flash more powerful exception, refer to its instructions bar.2 in the dark place, if the subject is the background of large area lighting occasions, such as you go to the underwater world, through the tunnel when shooting underwater world, such as the color of the musical fountain, with a flash but when solved by pitch-dark, exposure compensation.It doesn't work to use flash in such a wide range of fountainsNo flash, increase the exposure time to achieve the desired effect3 objects near, for example, within 15 cm or less, usually do not use flash, otherwise the brightness of the object surface is not uniform, and some parts may be overexposed.4 when there is an obstacle between the flash and the object, for example, when the shot is near, the lens may completely block the light of the flash and lose its function.To avoid possible flash, red eye: very simple, almost all of the cameras have red eye flash mode, note that the speed of time this mode will be extended, to hold the camera, or use three tripod.Avoid exposure, uneven, or a big bright spotWhen the object surface is light, flash light reflection will leave a big bright spot in the picture, undermine the overall effect, such as shot glass window objects, wrapped a layer of plastic film, and the objects in the film computer boards, will also have a strong reflection, it is best to remove film film, reflection can be far away from the object (the camera zoom lens to adjust the screen size), the most important thing is to transform the camera angle, side shooting, can make the spot reflection to the outside of the screen (Figure).A large bright spot appears in the center of the circuit boardThere's no point on the sideUse flash as auxiliary light sourceThe flash is not only used at night, but at any time, as long as the light and shade contrast of the different parts of the object is too large, the flash can be properly compensated by flash. (as in Fig.)Without flash, the object is bright and black belowThe use of flash assistance lighting, the whole is brightNight portrait with a light background: correct use of slow sync flash modeThe use of flash, shutter speed will be accelerated, but if the background is pretty lights, it will seem so underexposed, now many digital cameras have slow sync flash mode in this mode, the shutter speed is not open because the flash becomes fast, light may flash two times, keep the shutter open during the first open the shutter, or for a longer period of time after the flash flash, or for a period of time, no matter what kind of treatment method, the principle is the same, namely the theme and background are the proper exposure light, attention should be paid to the exposure time, must hold the camera, or with three tripod. And remind the subject to maintain posture don't move in before and after the bright flashing light in the seconds or image will shake hands with mobile or object and virtual ghost. In addition, when a light background is dark, often needto increase the exposure compensation, because the subject is the closer the flash under the action may be too bright, advised to properly reduce the flash intensity, prevent excessive exposure, reduce the strength of the concrete methods to flash back.Using standard flash mode, the subject is bright and the background is not clearUsing slow sync flashes, both the subject and background are photographedPay attention to effective distanceGeneral camera flash power is relatively weak, so the range is limited. When the day light, strong, backlighting film effective distance of only 1-2 meters, the night is long, but the digital camera flash range generally less than 3-5 meters.An object with a phosphor screenFor example, monitors, televisions, etc., the screen is luminous, and the frame shell does not emit light, so you need to use a flash to shoot intact and bright. However, because of the reflection of the screen glass, it is best to side to shoot (left, right, upper and lower angles can be),In order to avoid a major bright spot in the middle.(Fig. 3/4)Without flash, the screen is bright, and the black borderAfter use, all clearIn addition, due to the screen refresh rate, and scan rate of digital camera will beat, causing a slow rolling dark, the solution is to reduce the shutter speed (such as slow sync mode), sometimes it repeated the experiment several times before they got satisfactory results (Figure)Camera and display refresh frequency difference caused by rolling dark areaReduce the shutter speed to get the normal pictureIn the use of flash in the waterThe water absorption of light is more serious, so the underwater photography light is very poor, only in the underwater flash range to reach half its effective distance, to avoid the problem of insufficient exposure. In addition, if you are shooting across the glass to the water body, the flash should be close to the glass wall, or light is reflected, but because the camera more often than the location of the flash is prominent, so in the actual operation is hard to realize, this is probably the only external flash in order to solve the problem, or simply without flash and by extension the exposure time to shoot.How to adjust the brightness, flashThe maximum brightness of the flash is generally determined byits own characteristics, it is impossible to increase, but to reduce the intensity or can, method is to use gauze or transparent paper cover, generally a layer of gauze can be reduced to 50%, the 2 layer can be reduced to about 1/4. In actual combat, often do not have such conditions to find a gauze, then the easiest way is to use a finger directly blocking flash! Note, don't stand in the central part of the flash, but from the edge to the central block, the fingers to close, this method is very effective.Keep clean, pay attention to the lensWhen night flash, we must pay special attention to the lens is clean, it is believed that many friends think. The digital camera has a generally protective glass, which if there is dust, during the day may have little effect, but in the evening when the use of flash, will cause obvious spot. Beijing wind, I have a shot at night suddenly found a suspicious spot picture. (Figure 13) look carefully, there are a large number of white spots in the picture.Thought it was a light, and later realized that the possible lens is dirty, wipe clean and take it all normal, but a lot of photos but need to delete remake to spend extra time to clean the importance of visible camera.The additional external flash flash techniques -- the use ofWhy do you want to use external flash? The reason is because the flash camera position, built-in properties are fixed, not to provide more features and flexible setup, such as the abovementioned, in order to avoid the central flash highlights, had to side angles, if must center position picture of how to do? If the shooting object area too, do not even light up?...Only an external flash can give you more control.In the current mainstream digital camera, and not all can be external synchronous flash, you must first understand your machine is supported, and what support interface, if has the ability of words, very lucky, you can use it skillfully to further improve the photography skill!Use indirect flashWhat is said above is direct flash, that is, the flash directly targets the object, while in many other cases it is more advantageous to use indirect flash. The so-called indirect flash flash exposure is to the ceiling or wall or umbrella, using their diffuse uniform irradiation target, this photo shoot, the light will be more gentle, even without a trace of flash! Only external flash lights can do this easily. In the use of indirect flash, on the one hand, the power of the flash should be strong enough, in addition, the ceiling or wall should be dominated by white, otherwise the effect will not be good!Use special continuous flash to achieve special effectsIf the flash supports a continuous burst of light, the B or T gates of the camera (not all digital cameras have these features) have some special effects. For example, a moving object can take a series of tracks. For larger scenes, flash can not even lightup when the camera with B T or, in one or more flash times from different angles by irradiation, the photo will be the overall brightness will be smooth and soft, and even flash caused even the shadow of it is very difficult to see. These two techniques are difficult and have some limitations.。
摄影技术基础：闪光灯用光技巧
摄影技术基础：闪光灯用光技巧展开全文①机位直接闪光将闪光灯直接装在相机上闪光，使用方便，但光质较硬也较平，且主体离背景（如墙）较近时，易产生令人讨厌的阴影。
②侧位直接闪光也叫离机闪光。
用闪光同步线，将闪光灯拉离相机，从斜侧面，稍高的角度向主体打光，可克服平光效果，产生立体感。
也可使阴影状况得到改善。
③反射闪光利用闪光灯头可以向上翘或左右转动的功能，室内拍摄时，朝天花板或边上的墙面打光，利用反射光照明被摄主体。
这时光质比较柔和，且无阴影，由天花板反射闪光，还可以使主体前后其他物体的亮度与主体亮度比较接近，不至于出现机位直射时的近景一片白，远景一片黑的现象。
当然，反射闪光时的曝光计算公式也有所改变，具体为：光圈=闪光指数×0.7÷（入射距离+反射距离），或者不乘0.7而开大一级光圈。
反射闪光④直接漫射闪光将闪光灯头蒙上两层纱布或用柔光纸挡住，可以形成直接漫射闪光。
这种闪光只能改变光质，而不能改变光位。
阴影减弱，但不能完全消除。
一般需加大1～2级曝光，若用自动挡，可选用光圈较大的挡位，且最远射程会缩短。
⑤慢门同步闪光慢门同步闪光是用1/4秒或1/2秒以下的快门速度闪光拍摄。
用慢门同步闪光拍摄夜间人物，既可照亮人物，又可留下较完美的夜间背景景色。
用慢门闪光，还可使运动的主体产生虚影效果。
若闪光灯与相机完全脱离，在快门即将关闭时人工激发闪光，还可以在运动物体的身后拉出虚影，产生后帘同步闪光的效果，不过应选较深色的背景或在较黑的环境下使用，并用三脚架固定相机。
⑥闪光作辅光在室外侧光或逆光下拍摄，可用闪光灯作辅光提高暗部亮度。
一般快门速度取同步速度，并据此算出顺光时的光圈值，按该光圈值收小一挡作为闪光辅光时的亮度挡，用指数除以该值，即可获得闪光灯辅光时离主体的灯距了。
如果要改善光质，可在闪光灯前加三层纱，并按开大两挡光圈重新计算闪光指数（即原指数×0.5），再进一步获取灯距，确定灯的位置。
如何正确使用单反相机的闪光灯
如何正确使用单反相机的闪光灯随着科技的不断进步，单反相机已经成为许多摄影爱好者的首选。
而在摄影中，闪光灯作为一种重要的辅助工具，能够帮助我们在不同的光线条件下获得更好的拍摄效果。
然而，如何正确使用单反相机的闪光灯却是许多人头疼的问题。
在本文中，我将分享一些关于如何正确使用单反相机的闪光灯的经验和技巧。
首先，我们需要了解闪光灯的工作原理。
闪光灯通过释放强光来照亮被摄对象，以补充或改善现有的光线条件。
然而，过度使用闪光灯可能会导致照片过曝或反光过强的问题。
因此，在使用闪光灯时，我们需要根据不同的拍摄场景和需求来调整闪光灯的亮度和角度。
其次，了解闪光灯的曝光补偿功能是非常重要的。
曝光补偿功能可以帮助我们在使用闪光灯时调整照片的亮度。
在大多数单反相机中，曝光补偿功能通常以“EV”（曝光值）的形式呈现，可以在相机菜单中进行调整。
通过增加或减少曝光补偿值，我们可以在不同的光线条件下获得更好的曝光效果。
此外，闪光灯的角度也是需要注意的。
通常情况下，直接将闪光灯对准被摄对象可能会导致照片出现硬质的阴影和不自然的光线效果。
因此，我们可以通过使用闪光灯反射板或软盒来扩散光线，以获得更柔和和自然的照片效果。
此外，可以尝试将闪光灯调整到不同的角度，以改变光线的照射方式，从而创造出不同的拍摄效果。
另外，了解闪光灯的同步速度也是非常重要的。
同步速度是指相机快门和闪光灯之间的配合速度。
如果快门速度超过了闪光灯的同步速度，可能会导致照片出现黑色阴影。
因此，在使用闪光灯时，我们需要根据相机的同步速度来调整快门速度，以确保照片的曝光均匀和准确。
此外，了解闪光灯的色温也是非常重要的。
不同的闪光灯可能具有不同的色温，这可能会导致照片出现色彩失真的问题。
因此，在使用闪光灯时，我们可以通过使用色温滤镜或白平衡设置来调整照片的色彩平衡，以获得更准确和自然的色彩效果。
最后，我们还需要根据实际拍摄需求来选择合适的闪光灯模式。
大多数单反相机都提供了自动、手动和TTL（通过镜头测光）等不同的闪光灯模式。
闪光灯的应用和技巧
闪光灯的应用和技巧闪光灯是摄影中常用的辅助光源，广泛应用于各类摄影场景中。
它能够提供照亮被摄体的光线，有效消除或缓解拍摄过程中的阴影和暗部问题。
除了提供照明作用外，闪光灯还可以用于创造特殊的光影效果和解决特殊拍摄需求。
以下将介绍闪光灯的应用和一些技巧。
闪光灯的主要应用场景有以下几种：1.室内摄影：在室内拍摄中，光线通常不够充足，此时使用闪光灯可以提供足够的光线，使照片更加明亮和清晰。
2.夜景摄影：在夜晚拍摄中，闪光灯可以帮助提供前景的照明，使被摄体与背景光线更加平衡。
3.逆光拍摄：在逆光条件下，使用闪光灯可以解决前景过暗的问题，使照片更加均衡。
4.高速拍摄：在拍摄高速运动物体时，闪光灯可以提供高速短暂的光线，冻结运动物体，得到清晰的照片。
下面是一些使用闪光灯的技巧：1光线角度的选择：闪光灯的角度会直接影响照片的效果。
垂直于摄像头的角度会产生较强的阴影效果，而将闪光灯的角度稍微倾斜，能够使阴影变得柔和，效果更加自然。
2使用闪光灯柔光罩：闪光灯柔光罩可以帮助扩散光线，使其更加柔和。
柔光罩能够减少光线的硬度，产生柔和的光晕效果，适用于人像和室内摄影。
3调整闪光强度：闪光灯的强度可以通过调整闪光灯的功率来控制。
适当调整闪光灯的强度，可以避免过曝或曝光不足的问题。
4使用闪光灯补光：在一些情况下，摄影场景的光线可能不够充足，此时可以使用闪光灯作为主要光源，提供足够的光线。
5自动对焦辅助功能：闪光灯在自动对焦辅助功能中也起到了重要的作用。
在低光环境中，闪光灯能够辅助相机进行自动对焦，提高对焦的准确性。
6多闪光灯配置：用多个闪光灯组合配置，可以创造出更丰富多样的光影效果。
通过控制不同闪光灯的强度和角度，可以制造出更具层次感的照片。
7线光效果：在黑暗环境中，通过闪光灯的闪烁效果可以创造出有趣的线光效果。
可以使用一道线光或交叉线光来增强照片的视觉冲击力。
8色温调节：在拍摄时，如果闪光灯的色温与环境光不一致，会导致照片的色彩失真。
数码相机闪光灯有什么使用技巧
数码相机闪光灯有什么使用技巧摄影的艺术是光影的艺术，光与影组成了摄影最基本的元素，但是自然光并不是完美的，它井不能出现在每一个需要照射的地方，我们可以通过使用闪光灯便更自如控制拍摄现场的光线，通过组合闪光灯和自然光，创作更靓丽优秀的人像作品。
下面是小编为大家精心推荐闪光灯的一些使用技巧，希望能够对您有所帮助。
闪光灯使用技巧自动闪光通常，傻瓜相机(使用胶卷)与数码相机在不做任何设定变动的时候，闪光灯模式都预设在“自动闪光”模式下。
此时，相机会自动判断拍摄场景的光线是否充足。
如果不足，就会自动在拍摄时打开闪光灯进行闪光，以弥补光线。
我们大部分的拍摄，“自动闪光”模式都足以应付。
消除红眼“红眼”现象在拍摄人像照片(尤其是比较近的距离、环境较阴暗)时常会发生。
这是由于眼睛视网膜反射闪光而引起的。
如果你不想让拍摄出来的人或动物的眼睛出现“红眼”，可以利用数码相机的“消除红眼”模式先让闪光灯快速闪烁一次或数次，使人的瞳孔适应之后，再进行主要的闪光与拍摄。
关闭闪光(强制不闪光)顾名思义，就是强迫数码相机关闭闪光灯。
不管拍摄环境的光线条件如何，都不准闪光。
此功能最适宜于静止使用闪光灯的地方进行拍摄。
如笔者就曾经利用此功能在峨眉山万年寺拍摄金佛、在故宫拍摄“龙珠”。
此外，借助此功能在黄昏或弱光环境更能营造出自然的拍摄气氛。
强制闪光也就是“关闭闪光”的相反，即不管在明亮或弱光的环境中，都开启闪光灯进行闪光。
通常用在对背对光源的人物进行拍摄。
因为拍摄人物时，如果主体处于背光位置(如拍摄一间光线黑暗的房屋中的人物，主体背对着明亮的窗户)，主体的正面就会处于阴影中看不清楚。
此时可借助此功能，在闪光灯的有效覆盖范围内拍摄到主体受光均匀的照片。
慢速同步闪光在光线昏暗的环境下拍照时，如果使用闪光灯加较高的快门速度进行拍摄，很容易造成前景主体太亮，甚至是白晃晃的一片，而背景却依旧灰暗，无法辨别细节。
而“慢速闪光同步”会延迟数码相机的快门释放速度，以闪光灯照明前景，配合慢速快门(如1/5秒)为弱光背景曝光。

This method is very effective.Note that the lens is kept cleanWhen using flash at night, pay special attention to the cleanliness of the lens, which is believed to be unexpected by many friends. In front of the lens of digital cameras, there is usually a piece of protective glass. If there is dust on it, it may not affect much during the day, but when the flash is used at night, it will cause obvious spot. Beijing sandstorm big, I once in the evening shooting, suddenly found the picture has suspicious spots. (Figure 13) look carefully,There is a lot of white dot in this picture.Thought it was a light, and later realized that the possible lens is dirty, wipe clean and take it all normal, but a lot of photos but need to delete remake to spend extra time to clean the importance of visible camera.Additional skills for flash - use of an external flashWhy use an external flash? The reason is because the flash camera position, built-in properties are fixed, not to providemore features and flexible setup, such as the above mentioned, in order to avoid the central flash highlights, had to side angles, if must center position picture of how to do? What if the area of the object is too large to be even illuminated?...

In the use of indirect flash, on the one hand, the power of the flash should be strong enough, in addition, the ceiling or wall should be dominated by white, otherwise the effect will not be good!Use special continuous flash to achieve special effectsIf the flash supports a continuous burst of light, the B or T gates of the camera (not all digital cameras have these features) have some special effects. For example, a moving object can take a series of tracks. For larger scenes, flash can not even lightup when the camera with B T or, in one or more flash times from different angles by irradiation, the photo will be the overall brightness will be smooth and soft, and even flash caused even the shadow of it is very difficult to see. These two techniques are difficult and have some limitations.。
单反相机闪光灯使用技巧
单反相机闪光灯使用技巧单反相机闪光灯是摄影中常用的一个拍摄技巧。
它可以为照片提供光线，改善照片质量。
在使用单反相机闪光灯时，有一些技巧可以帮助我们拍摄出更好的照片。
首先，我们应该选择合适的闪光灯模式。
常见的闪光灯模式有手动模式、自动模式和 TTL 模式。
在手动模式下，我们需要手动调整闪光灯的强度和角度。
在自动模式和 TTL 模式下，闪光灯会根据当前环境光线的亮度自动调整强度。
其次，我们应该注意闪光灯的角度。
闪光灯可以从不同的角度照射光线，改变光线的亮度和方向。
通常来说，闪光灯要避免直射人物或物体，以免照片中产生剧烈的阴影。
我们可以将闪光灯朝天花板或白墙上反射光线，使光线更柔和均匀。
另外，使用闪光灯时要注意光线的色温。
闪光灯的色温一般为5500K，而自然光的色温则根据时间和天气的不同而有所变化。
为了保持照片的色彩准确，我们可以调整相机的白平衡设置，或者使用闪光灯的色温滤光片来匹配环境光线。
此外，我们还可以改变闪光灯的强度和闪光灯的运动模式。
调整闪光灯的强度可以改变照片的明暗度，根据实际需要进行调整。
闪光灯的运动模式可以选择常亮模式或者快闪模式。
在拍摄运动场景时，快闪模式可以冻结运动的瞬间，拍摄更清晰的照片。
最后，我们还应该注意闪光灯的使用范围。
不同的闪光灯根据功率和设计有不同的使用范围。
一般来说，闪光灯的使用距离为其最大功率的1/4到1/16倍。
超出这个范围，照片可能会有光线不足或过度曝光的问题。
总之，单反相机闪光灯是摄影中不可或缺的一个工具。
通过选择合适的闪光灯模式、调整角度和强度、注意光线色温和使用范围，我们可以拍摄出更好的照片。
无论是人像摄影、风景摄影还是运动摄影，闪光灯都可以提高照片的质量，让照片更加生动、精彩。
数码摄影之闪光灯应用技巧完全宝典
数码摄影之闪光灯应用技巧完全宝典Company number：【WTUT-WT88Y-W8BBGB-BWYTT-19998】● 前言如今，数码相机的异军突起大大地改变了我们的摄影方式，超出想象的强大功能足以激发每一个使用者的拍摄欲望，作为一个玩家，如何充分利用数码相机的优势，提高拍摄效果笔者认为，器材本身只是一个方面，更重要的则是拍摄技巧，即合理、正确地运用光学和摄影知识，挖掘器材本身的潜力，而数码相机则恰恰是一个最易于上手，可无成本做试验的器材。
摄影技法博大精深，非三言两语能道得清楚，本文单从闪光灯的角度，特别针对数码相机的特点，为大家讲解一下数码摄影之法门，班门弄斧之处还望斧正，权做抛砖引玉吧！● 闪光灯技术之基础篇说到闪光灯，诸位可能觉得很简单--晚上拍照时用呗。
这只说对了一部分，其实闪光灯是一个用途非常广泛的辅助工具，它是摄影光源的一种，当拍摄时，周围环境的自然光源(日光)或人工光源(灯光等)不足的时候，闪光灯就成了弥补这一不足的机动光源。
抛开种类繁多的各种类型的闪光灯不说，本文单指最通用的，各种相机都内置了的那种万次闪光灯，它通过电容和线圈储存能量，在瞬间释放并感应出高压，激发惰性气体发出脉冲光源，从而获得极强的瞬时功率。
由于闪光灯作用时间很短，一般的说，相机的快门速度已经无法起到调节光通量的作用，而对于多数数码相机来说，由于对光线的响应速度没有胶片快，因此甚至不需要去调整光通量，在光线不足的场合，只要选择了闪光模式或相机自动进入该模式，则快门速度会自动加快到一个比较短的值。
这通常不会出什么问题，但在环境光线充足的情况下，近距离拍摄时不慎启用了闪光灯则曝光过度的情形也会出现。
而另一方面，如果环境光线很暗，则过高的快门速度将使得闪光灯照有效范围外的景物漆黑一片。
了解不同物体表面的反光特性可以更好地使用闪光灯，由于不同物体对光存在不同的反射、散射能力，而闪光灯相当于一个点光源，如果被摄物体是、或附近有玻璃、大理石、电路板等一类平整、光滑的表面则在照片上会形成一个亮点，破坏整体效果。
闪光灯摄影实战技巧
闪光灯摄影实战技巧闪光灯摄影实战技巧其实在闪光拍摄中，你有很多事情可以做。
这里所介绍的几条闪光拍摄技巧既实用又易于掌握。
掌握了这几个技巧，可以说能够在很大意义上改善闪光摄影的拍摄质量。
下面一起来学习一下吧！除了离机闪光需要热靴闪光连线、pc接口闪光连线或是同步闪光引闪器之外，其他几条并不需要任何额外附加设备。
这样,不论是使用单反相机的外接闪光灯系统进行拍摄，还是使用便携式相机的内置闪光灯拍摄，你都可以拍摄出优秀的闪光摄影作品。
一.巧用内置闪光灯袖珍式相机、便携式相机和中低端单反相机通常都配备有内置闪光灯，可以在拍摄中通过闪光来补充光线，以达到光线的平衡。
通常人们会认为这种闪光灯可有可无，在正式的拍摄中不会发挥太大的作用。
但实际上如果灵活使用内置闪光灯，同时将其内在的潜力充分发挥出来，完全可以获得意想不到的拍摄效果。
需要注意的是，在使用内置闪光灯时，尤其是在镜头前安装有遮光罩的情况下，要避免因遮光罩、镜头镜筒遮挡闪光灯光线而出现黑影的现象。
使用内置闪光灯拍摄使用的光线是直接闪光，也就是说闪光光线是直接从闪光灯到达被摄对象。
使用内置闪光灯时，你需要做的只是将闪光灯设置在闪光补光拍摄模式，或是弹起闪光灯直接进行拍摄就可以了。
使用安装在闪光灯热靴上的外置闪光灯的拍摄光线一部分也是直接闪光。
你首先要做的是准确调整闪光灯灯头方向，使闪光光线正好落在拍摄对象上，其次要设置闪光灯的闪光模式，最终实现准确闪光。
如果要对拍摄效果进行精确控制，你就需要使用具有和支持TTL功能的闪光灯和相机系统。
二.反射闪光反射闪光相比直接闪光在人像摄影上可以取得更为柔和的光线效果，你可以通过天花板或是白色的墙壁作为反光板来完成反光。
来自于反射体的反光要比直接打到被摄体上的光线柔和得多，这种光线可以使人物造型更具立体感，画面更为生动。
另外，在具有两个人或三个人的纵深画面拍摄中，反射闪光要比直接闪光更能使被拍摄对象取得好的照明效果。
另外，反射闪光同时也能够有效防止红眼现象的出现。
相机闪光灯的使用技巧
相机闪光灯的使用技巧如果没有了光，那摄影就没有存在的意义了。
大自然中充满着各种光线，对照片的层次、色调、气氛都有着关键的影响。
但当光线不足时，人造光源就要派上用场，热靴闪光灯因携带方便并且色温接近自然光，是利用最多的人造光源。
下面是小编为大家精心推荐闪光灯的一些使用技巧，希望能够对您有所帮助。
闪光灯使用技巧白天户外人像补光——闪光灯作为补光室外拍摄人像进行逆光拍摄，主体与背景的反差很大，如果顾及主体进行曝光，那么背景必然曝光过度，而正常还原了背景，主体又曝光不足，这时就需要用闪光灯进行补光来平衡。
如下图某学院风格女装拍摄，当时拍摄环境是下午四点半的阳光下，人物逆光，脸部偏暗，拍摄这张照片时，先对环境测光，测光数据是光圈F5.6，快门是1/160，测光完成后，把相机切换到M档，设定好光圈快门，打开闪光灯，TTL模式，减1.5档输出，最终拍摄完成的图片，人物脸部曝光正常，环境氛围也得到了较好的体现。
逆光在女生的头发和衣帽周围勾勒出一圈温暖的线条，与背景隔离开来，同时也突出了人物主体，正面闪光灯补光。
拍摄构图时，注意用拍摄对象稍微挡住部分太阳的主体，以免眩光太厉害。
如若是在直射日光下拍摄侧光人物，主体人物明暗反差过大，导致拍摄出现阴阳脸的状况，这对拍摄柔美女性人像来说，可能是一个非常难以接受的画面效果，这时也需要通过闪光灯对人物的暗部进行补光曝光，可以面部强光为准，其明暗反差，通过闪光灯补光，一般控制在1：3到1：4比较合适。
拍摄步骤：(1)先针对背景来做测光。
然后切换至M模式，将光圈、快门值设定在方才的测光结果，需要注意快门必须是在闪光灯的同步快门范围内。
(2)使用TTL闪光灯或自动闪光灯对准拍摄主体进行补光。
注意事项：逆光摄影时，为了丰富画面层次和获得良好的色彩还原，需用闪光灯作补光。
一般来说，用作补光时不需要闪光灯发挥强功率照明，而要注意控制闪光亮度，避免补光过度。
一般可设定到相当于正常曝光不足两档左右。
数码摄影中闪光灯的使用技巧
数码相机已经逐渐普及，许多用户都开始使用数码相机拍摄旅游或家庭照片。
这次小手为大家介绍一些摄影中的常识，希望能帮助读者更好地理解摄影技术，掌握摄影技巧，拍摄出让朋友惊讶的照片。
光是摄影艺术中不可缺少的物质条件，它能给摄影艺术带来绚丽多彩的画面，从一定意义上来讲，摄影的基础就是光。
好的光线能使物体具有层次，让画面变得饱满，但是很多时候仅有现场的光线是不够的，我们还需要用到一些辅助光源，闪光灯就是其中的一种。
闪光灯所发出的光线与自然界中的光线不同，自然光线是连续不断的，而闪光灯是在曝光瞬间释放出来的强烈光线，因此使用闪光灯时更需要掌握一定的技巧。
以下是笔者在实际使用中总结出来一些心得体会，希望能和大家共同探讨。
一、微距拍摄要减光现在的数码相机一般都有内置闪光灯，使用内置闪光灯时要注意相机与被摄对象之间的距离。
距离太近会导致曝光过度，而距离太远会使得光线分布不均匀，导致曝光不足。
用户最好查阅数码相机的使用手册，了解内置闪光灯的使用范围，在这个范围内使用一般都能起到很好的效果。
利用数码相机进行微距拍摄，由于距离拍摄物很近，此时使用内置闪光灯只会导致曝光过度，所以需要进行减光处理。
减光就是减少闪光的输出强度，你可以在数码相机中进行调节，但这样还是不够的，光线依然很强。
你可以用手遮住闪光灯，注意手指要靠紧，这在一定程度上可以减少光线强度。
在实际使用中发现，简单的利用餐巾纸这一类柔软的纸张遮挡也能起到很好的效果，让光线变得柔和。
二、改变闪光的角度很多人在使用闪光灯进行拍摄时，习惯性地将闪光灯与被摄物体平行，以便让光线变得均匀。
但是在拍摄具有反光性的物体时，例如玻璃、各种电脑板卡时，会在物体上产生亮斑，破坏画面的和谐。
这个时候应适当改变数码相机的拍摄角度，从侧面进行拍摄，这样就能避免产生亮斑。
三、主体与背景反差大时适当补光不要以为只有在光线较暗的情况下才需要使用闪光灯，有时在光线充足的情况下，也必须使用闪光灯进行补光。
