数码摄影之闪光灯应用技巧完全宝典（Digital photography flash application skills complete collection）

Foreword

Today, 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 technology

When 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 energy

storage 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.
