Many people may think that the camera built-in flash is a more "chicken rib" function, its supplementary light effect is general, the light is straight and unnatural, and the range is relatively limited, so it is difficult to form a wonderful picture.

But if you only think of the flash as a make-up device, you may miss out on a lot of other interesting ways to play.

1. The disadvantages of the built-in flash in order to make good use of the flash, we first need to understand the shortcomings of the camera's built-in flash:

First, the light is too hard, second, the angle is single, and third, it is not convenient to control the brightness.

Well, in view of the above characteristics, we can use some tips to improve them, such as excellent light and brightness problems, we can cover them properly with translucent objects, such as a layer of white plastic bags, to soften the light.

Aiming at the problem of single angle, some of the built-in flash can adjust the angle appropriately, but it is also limited, so we can cover it with our hands or various objects when shooting, or find a reflector to be placed in front of the flash to have a different effect.

The effects of the above techniques are relatively limited, and it is difficult to compare with professional external flash, but it is also worth a try in case of emergency, which may form a more interesting picture.

It is also important to note that the closer the subject is to the flash, the brighter the subject is, and the greater the contrast with the background. If you want a more uniform light and shadow effect, you can make the subject closer to the background behind, or a little further away from the camera.

If the subject is too far from the background, the contrast between the light and shade of the picture will be larger. The function of the stop picture flash is not only to fill the light, it can also help the picture freeze and keep the main body of the picture clear.

Especially for the moving subject, using the flash to freeze the frame can not only achieve the effect of locking the moment, but also highlight the main body in the picture, but also highlight the details, but the disadvantage is that it does not support continuous shooting, so the photographer needs to have precise control over the shooting rhythm.

Sometimes we see some photographers turn on the flash during the day, which may be using its freeze function.

3. Back curtain synchronization when it comes to the stop function of flash, then we have to mention the interesting technique of "back curtain synchronization".

There are front curtain and rear curtain in the camera. After their respective work is finished, the photo is taken. When the shutter speed is fast, they are almost synchronized.

When the shutter speed is relatively slow, their working time will be obviously different. after opening the rear curtain synchronously, when shooting a moving object, the front curtain falls first, but the rear curtain has not yet dropped, and when the shutter is finally released, the rear curtain falls and triggers the flash at the same time, so that it can not only record the trajectory of the object, but also lock the last clear moment, and get an effect similar to this:

To put it simply, the use of this technique can not only record the motion trajectory like long exposure, but also capture a clear moment like ordinary photography, and put it in the same photo, for some dance, sports themes, very practical.

Set the camera to file B, find the menu-flash setting-built-in flash setting-select the rear curtain synchronization function to shoot moving objects continuously (Canon camera setting steps, if there is an external flash, you can also continue to set it on the flash). Release the shutter to trigger the flash to achieve this effect.
