| Digital Camera Flash Using GuideCamera flash as the camera an indispensable tool in low light conditions to provide good fill light effect. Although noise control with the ability to upgrade the camera,sometimes we can choose to use high speed to overcome the problems caused
By: www.sales-battery.com Although flash can be very good in many cases fill light to complete the work (especially the power of powerful external flash), but most of the primary player or the flash arm's length. The reason, the main light is too strong light easy to bring great ratio and screen distortion. However, this distortion can be achieved through flash shooting techniques specific to reduce, first of all, I'll introduce three common flash method. First, all the most common way of direct-type flash. In the news, we often see journalists use the bend in the camera when the camera flash. Obviously, the flash lamp facing the photographer's head, white flash, the whole hall is flashed. The direct-style shooting in a manner that the maximum range of the flash to flash by using the glow, of course, can also produce the greatest light ratio, resulting in the shadow of the most obvious, and has to be taken by "instant blindness" effect ... ... Relative to the direct style, the more "moderate" for the vertical flash mode, simply put, is to stand up and shoot the flash! This method is implemented using the reflected light ceiling light, light can become more flexible, but relatively less dazzling. However, if the ceiling is too high from the ground, or flash your "hammer" is not big enough, this method is not suitable! Finally, we run the flash reflection. The flash mode is rather special, the first point the flash head behind the lens, using the camera behind the object (such as walls) to the flash of light reflection to obtain a second soft natural light. Can imagine, this received light flash than the vertical method to obtain a more gentle nature of light, and for you for the flash power requirements and more stringent environmental requirements. In order to reflect the intuitive features of the three flash mode, I fixed the camera in flight, using different ways to shoot. Similar to ensure that the final exposure, we used different levels of flash exposure compensation, and to elect three photos comparing similar light. The shadow of the flash, we can see that they are very intuitive different. One reflection caused by the flash of light so that shadows look very soft and natural, very close to the effect of natural light; and vertically from the shadows the flash is not too stiff, but the optical path of the reflected light from the top down has brought a very a long shadow. As for the direct flash to bring the edge of the clear strong shadow, has some lack of coordination of the whole picture. In detail, the flash is also reflective of the pictures taken with more highlights and shadow detail; and if the direct flash, the photos will look a bit "stunned", the color transition is not natural, than at high light exposure, dark death black. Imagine if the direct flash shot with beautiful women, who not only flash a headache, and this effect is bad enough. Three flash mode, it seems very easy to understand, it sounds too abstract, here, I listed three ways for the people the advantages and disadvantages. Advantages and disadvantages of direct-type flash: The best use of light source and looks farther, wider shot, shoot more light; In the same scene, the light source means full use of "low carbon" energy saving. Images taken over a great light, so there is loss of detail, shadow comparison stiff; Portraits when the xenon lamp direct eyes, ranging from dizziness, while in temporary blindness. Advantages and disadvantages of vertical flash: Using the soft reflected light ceiling, efficiency can still, with higher utility; Exposure under normal circumstances, direct-type flash mode than the natural color of the pictures taken, and more rich in detail; Basically put the light on the human eye damage. Compared to direct style, an increase of 0.7 to 1.0EV flash exposure compensation, costs of electricity but also nearly twice as many; By the use of environmental constraints, there must be a lower roof; Easy to produce a long shadow, such as the film has a head curtain girl, there may be a shadow over her face. Advantages and disadvantages of flash reflection Close to the fine details of natural light; Basically eliminate the shadow of the interference; Reflected light and soft, not to hurt the eyes. Light utilization is low, in many cases the maximum power directly to work in flash, very power; Highly vulnerable to use of the environment constraints. The content of the above lists all the most common pros and cons of the three flash modes, interested users can try. I believe you read the above techniques are simple to use flash, the flash has been for this common but it is quite a bit mysterious thing with a whole new understanding. Of course, then again, if you want the theory into practice, need to practice much more. 【 The Second Largest Battery Supplier On US Market 】 NIKON en-4 battery http://www.sales- CANON eos-300d Battery http://www.global- sony np-ft1 battery http://www.sales- # # # www.global-Battery.co.uk A excellent replacement batteries source: Save more than 30%!
