========================
[Concept]
Belong to the photographic products, can play the role of fill light.
========================
Run out of principle
The reference indoor studio light
========================
[Role]
--------------------
1 [fill light]
Essentially change the laws and rules of pure natural light shooting can be done completely ignored the leading role of the sun, and can be more proactive and effective use and control the effects of sunlight.
--------------------
2 artificial 外拍 lights use, combined with the camera's shooting settings, you can create a strange location shooting of pure natural light can not reach the artistic effect.
Control of light intensity, angle, light quality and color can completely obey subjective performance intent of the photographer
But technically, the effect of control has its particularity.
========================
[Equipment configuration]
Often used in photography studio long lights produce illumination is far and outdoor sun can not be mentioned in the same breath, so almost no role in the location shooting.
2. The ideal 外拍 lighting equipment generally should choose flash is appropriate.
3 outdoor photo light varieties to choose from a lot of the general production studio flash manufacturers have produced.
4. 外拍 with a flash from the appearance and performance and studio of the same. Can also be used as indoor and studio lights with the same power, but relatively speaking slightly higher price than pure indoor lights.
Outdoor Flash and indoor lights essential difference is that the power attributes and power accessories. Unlike indoor lighting and DC power supply.
Buy Outdoor Flash also must be equipped with a the outer DC battery and DC wireless cited flash accessories.
Photographer using film cameras also need to configure the flash meter.
8. The dedicated outdoor Flash auxiliary accessories are many, lighthouse, diffusers, umbrellas, honeycomb, color film, light barrier, etc., needed to buy another.
Flash models are generally identified by power size, such as 300, 400 or 600, the greater the value, the greater the power.
The Power size can also be adjusted as required. The within budget permits, 外拍 recommended that as much as possible to select high-power lights.
10 addition, the quantity of the flash configuration is not necessary too, because outdoor solar may be utilized.
11 beginning when recommended by a single lamp used in conjunction with sunlight and reflectors future operating proficiency and need separate additions.

[Tips]
1. Exposure settings of the camera must be full manual (M file), any camera's automatic metering and automatic exposure program can not be induced in the amount of flash instant exposure.
Flash photographer principle must flash exposure characteristics have mastered.
Instant luminous flash duration is very short, usually less than a thousandth of a second. Camera control only control the amount of flash exposure and shutter speed and aperture, and sensitivity settings.
Shutter speed as long as, in any case change in a flash synchronization within the aperture and sensitivity settings unchanged, the same amount of flash exposure.
4, while the effect of the flash and the sun at the same time, because the sun is a continuous light source, the setting of the shutter speed is directly related to the amount of light of the sun.
Then, out of these two light sources, the exposure of particularity, to produce a flash 外拍 special control technology:
First set the aperture size to control the amount of flash exposure and adjust the shutter speed to control the amount of natural light exposure, after flash synchronization within.
Effective use of this particular technology, you can create a very special artistic effect.
We can put your subject in flash-based light source, the environment in the sun as the light source.
Select and fixed right main flash exposure aperture value, and then adjust the shutter speed in the shooting, At this time, the amount of exposure of the subject has been aperture fixed almost no change in the brightness of the environment can greatly pressure dark, and the subject is prominent, and environment separated.
5 when using flash 外拍, the subject should be selected environment pull a certain distance.
The main body and the environment at a different light irradiation range, to facilitate each independently control the respective exposure amount.
6. Different characteristics of flash and the light of the sun, the sun away from the earth, rays of sunlight to the ground objects have nearly parallel.
The flash is a point source, the point source lighting at different distances and the subject luminance on the existence of the inverse square relationship.
In other words, when the distance of the flash with your subject reduced to half of the original, in the case of flash output power constant, the brightness of the main body irradiation generated will be four times. Therefore, the photographer can effectively utilize distance regulator to control the brightness of the flash coverage.
In general, the flash closer to your subject, the more intense the light efficiency of its main performance; contrary, it is better integrated with the environment.
7. 外拍 dedicated flash can be equipped with a lot of light efficiency accessories, installation of soft mask allows light qualitative change very soft, light barrier, can use light more accurate.
Interpolation, can change the color of light with a different color film.
Outdoor photo light only as a fill light uses natural light conditions, can be directly produced in any position irradiation reflectors on the main fill light intensity controllable leeway can more freely adjust the position.
