2. The use of reflex to shoot, generally professionals use SLR cameras to create, and the aperture and speed are set manually according to the photographer's experience, rather than measured by the camera.
Therefore, there is no metering, overexposure or underexposure in both cases.

The working time of the flash is extremely short, generally only a few thousandths of a second, which is much faster than the shutter speed, so the shutter speed has little effect on the flash. Usually 60 a second is needed to ensure adequate sharpness, image stabilization, and background light equalization.
The metering system is still the camera's, and when the camera finds that the light on the object is bright enough, it notifies the flash to stop flashing. In fact, it is to control the duration of the flash to control**. Shutter speed has little effect.
2. Reflective photography is actually the same as appeal, regardless of direct flashing or reflective flashing, as long as the brightness of the surface of the object reaches the standard value that the camera thinks, it will notify the flashing light to stop working. The advantage of this is that after the secondary diffuse reflection, the light source will be much softer and will not leave a stiff shadow. Of course, in this case, the flash will be greatly lost, and the corresponding flash distance will be greatly shortened, and it is generally only used in places with limited space.
If a hall that is too empty reflects the light through the roof, it is often insufficient due to the power of the flash.

2. When the light ratio is very large, such as when shooting a portrait, there is a strong light behind the portrait, and at this time, it can also be artificially forced to flash to reduce the light ratio between the portrait and the background light, so as to obtain a more balanced exposure. Of course, it doesn't mean that turning on the flash will always get the right exposure;
3. If the shutter speed is greater than the synchronization speed of the flash, there will be black streaks on the ** due to the incomplete release of the shutter;
4. Using the maximum synchronization speed specified by the flash, you can get a fully lit **, and you can also ensure the shutter speed;
5. Use a slower shutter speed to shoot, and the light in the environment will also affect the light effect of the picture, and the light effect of ** is more natural.
