Wide Angle lens for canon bp-511a battery shooting Angle wide named, apply to shooting distance and range of nearly alike. Wide Angle lens can deliberately exaggerated prospects shows strong sense, both near and perspective.

Many people do canon nb-2l battery not agree with use wide Angle lens to film figures. Wide Angle lens when shooting the covers a wider range, is not easy to outstanding theme.

In natural light (sun) photography CANON NB-1L Battery, generally do not need to assist illume, because natural light to have enough brightness. But in some qian condition is different, such as in the strong sunlight shooting side light or backlight close range and features characters, or at the window filming activities in direct sunlight, and like the backlight in indoor natural light conditions such as larger scene shooting, or because of light and shade contrast is too big, or scenery for light not divide evenly, will need to fill light. Small flash is light and easy to control the amount of light, colour temperature is appropriate, can also with multiple lights flashing, is an ideal additional light source, if used well, help to make up for the deficiency of the natural light, and improve the quality of photos. canon lp-e10 battery

Practice proves, in natural light, can add with the flash control contrast, and can adjust the color temperature, at the ZaoXingGuang when use. In the light of the image, mixed intake is very exquisite also, soft, can produce a good visual effect. Now come first talk about flash and outdoor natural light to cooperate. Here's the natural light outdoor, including said direct sunlight and cloudy scattering light. In direct sunlight with the flash photography, supplement the purpose of is abate, lighting the light and shade contrast, scenery and make the shaded part shadow grain fully show. Level Therefore, only when the subject body in side light or backlight to need to add state with flash. In this case, because the flash is used as auxiliary lighting, so shall, subject to exposure to the sun of flash intensity of illumination must be controlled, not the leading role.

Now with the light photography as an example: in direct sunlight shooting side light exposure can face strong character, the light and shade contrast, subject, through the flash light supplement, general control in 1:3 to 1:4 is more appropriate. If using automatic flash light, the light and shade contrast to control the proportion is very simple, as long as the choice of the automatic aperture on flash level than camera, choose used in large aperture to the level 1 and a half can. 1 If flash on the class won't have, but also through the adjustment on the camera aperture and shutter speed exposure to solve the combination. If use hand controllers can be adjusted to flash, flash power device, or flash to be taken the distance from the body, or in light and yarn way, to control the amount of light flash: here are two points need to say that, if your camera is focal plane shutter. Can only use slow film, or on camera and a neutral grey filter, because of the focal plane shutter speed is usually synchronous flash 1/60 seconds or 1/125 SEC (at present more advanced camera 1/250 of a second), such as a fast film, in the strong sunlight does not apply.

In direct sunlight CaiSePian filming, such as add with flash, should pay attention to the change of the color temperature sun. Especially after sunrise and sunset before section of time shooting like, in order to keep the light tonal and atmosphere, must be in flash combined with lower color temperature of the filter. In YinYuTian scattering light next on people, often object for shooting pictures by light, contrast is very weak, dull and fundamental key, dreary gray flat photos. In this case. Available for ZaoXingGuang flash, with the flash set side light and backlight light effect, such as for increasing contrast, rich levels of purpose. Detailed practice has two kinds: one kind is the flash light, it, or on the side of the body was taken out side light, high effect; Or in dorsal high, hit the rim light effect. Exposure can face natural light shall prevail, the characters of flash power and distance to the camera aperture used more than 1 to level 1 and a half can. But to do that, need a long wire. Another kind is exactly as double lamp, can try a method of photography, only as light, one for a vice lamp, light a and light than can be according to need and decide. Different because exposure is natural light, vice lamp is the main task is a light, so the Lord in the determination of the power, vice light than camera aperture used less good level is, lest destroy the effect of natural light. canon camera batteries
