Experience of Natural Light and Flash Light

Often people ask the author, "What aperture and shutter are you shooting with?" instead of asking how to distribute light. Of course, it is human nature to ask this question. In today's fully digital photography, it seems familiar with the operation of various dashboards on the camera, turning to the "correct" number, as if you can take a good picture, so shooting. Fans go crazy to memorize EXIF's diaphragm and shutter data, purchasing the same equipment as those in Daren and photographic books, as if they could shoot well in this way, but in fact they are not. To be honest, I don't know the exact "placard" in the photographic scene. In fact, the specific aperture value and shutter speed are not important in the photographic layout. It is important to balance the interaction between ambient light and flash. The factors affecting the use of light are shutter speed, aperture,..., flash output and lamp spacing. But how to balance the power of the flash and the light on the spot? Skilled photographers tend to think a lot of thinking in one action. It's not easy to discuss it independently, but the author still tries to explain it to all the readers. It is not a problem that the scene light is very dark, but it can reduce the interference to the flash. However, if there is a big difference in brightness between the scene light and the background, then the choice of supplementary light or photographic angle becomes very important. We usually light the background or mercerize people from the background to highlight the characters, so as not to hide in the dark, can not highlight.
AV+TTL flashing lights
Using flash to shoot in natural light, there is an exposure that can make the light of the flash merge with the background light. Golden dot. Generally speaking, using TTL flash mode, adjusting the exposure of the camera to Av (or A) aperture and presupposing automatic exposure, we can easily get this result. If you want to shoot outside, you may as well use flash. The reference value is obtained by using AV + TTL flash to trigger the spot light. This reference number is very useful for us. Usually the author will write it down and apply it to M mode.
Use all the light available at hand
There is no need to use flash during the day. This concept is deeply rooted in many photographers'minds, for the reason that there is plenty of light. Many people prefer to use reflectors during the day, rather than think about using flash to supplement the light. In some cases, photos taken with natural light are very poor, but many people still do not want to use flash to improve the light. Slice. It's not a correct idea to avoid problems and insist on not using flash because you are not good at using flash. Flash can be used to reduce the contrast between people and background. And in places where you can't use reflector, it's more necessary to use flash. I often hear many photographers complain about buying advanced flash for one year. In fact, using flash properly and correctly will only add points to the works. Flash as a lighting tool, but it is not just a light supplement tool, to understand the principle of flash trigger, first of all, to understand the lighting of natural light, in fact, flash distribution is also to use artificial light to simulate and recreate "natural light", that is, according to the principle of natural light to light distribution, excellent photography is not necessarily pure. It's only the scene ambient light or flash, usually the ingenious combination of flash and ambient light. Use natural light or specially arranged flash to highlight the atmosphere of the photographic scene. Flash can make up for the imperfect defect of natural light, that is, "artificial sun". The element of flash can be added to avoid pulling. High ISO hard spelling, improve the quality of photos, so that works more detailed. Playing with light is the basis of playing with photography. With light, there are shadows, which make the objects on the photo plane more three-dimensional. With light, the colors of all things are more vivid, and then the elegant surface will reflect a dazzling side. In the dim light environment at night, things that lose light suddenly become lifeless, and flash becomes the main tool to supplement light and illuminate at night. What's more, the reason why many people use reflectors is not that natural light has its shortcomings. Water, snow and wet asphalt roads are also natural reflective materials. Observing these natural phenomena, and using reflectors, flashes and other equipment to create the image they want, is not that what everyone pursues? Joe McNally, a well-known foreign photographer who worked for Time magazine and National Geographic magazine, also said, "All the light you can get at your hand is good light. Whether it's natural light or artificial light, Japanese master Yoshihiro Suzuki also said, "For professional photographers, flash is a necessary skill, just depending on how you use it." You have no reason not to learn to use flash. Compared with natural light, the quality of flash is much harder. Photographs taken with built-in flash are often underexposed and the light is stiff and unnatural, so many people think that flash is difficult to control. In fact, after the light control equipment such as no shadow mask or transmission umbrella to soften the light, you can get a variety of different effects. Although the illumination range and output of the flash are limited, it is still controllable. We can also control the flash in color temperature and intensity. The flash is not so uncertain.
