The problem of taking pictures About the flash, why is it dark?

If you turn off the flash, it will be much brighter.

This is because when you turn on the flash, the camera will use the flash as the main light source, and the camera will use a higher shutter speed to expose. But the flash light has no effect on the distant background at all, so the distant scenery is dark.

If the flash is turned off, the camera photometry finds that the light is very dark, and the camera will use the maximum aperture and slow speed for automatic exposure. At this time, as long as the camera is stabilized, the background will be much brighter.

If the flash is turned on, the illumination of the flash will be greatly attenuated with the increase of the irradiation distance, and the photos taken are unnatural, while the photos taken with living light have natural light. When the scene is dark, you can set the ISO of the digital camera to a high point (considering that high ISO has more noise, it is not recommended to set it to the highest value, and the imaging quality of high ISO is much better than that of small digital SLR). On the other hand, use a tripod whenever possible, if not.
