Apple's mobile phone flashlight suddenly stopped working.

The sudden failure of Apple's mobile phone flashlight may be due to the high flash temperature, insufficient battery power and low or high equipment temperature.

If you shoot video for a long time with the flash on, or use the device in a very warm environment, you may see a message indicating that the flash has been disabled, the iPhone flash function will be disabled, and the flash switch button will turn gray. This message will continue to be displayed until the equipment temperature drops.

If the battery of the device is low and the device is hot or cold, the camera flash and flashlight may not work properly. When the device is charged and returned to a more normal temperature, these functions will work normally again. If the flashlight still cannot be used at this time, it is recommended to contact Apple's after-sales maintenance equipment.

Introduction to the use of flash lamp

Flash is a kind of light compensation equipment, which can ensure that clear and bright pictures can be taken in dim light. When shooting outdoors, the flash can also be used as an auxiliary light source to emphasize skin color. Special effects can also be arranged according to the photographer's requirements.

Many times we will find it on the shooting scene. The effect of the background is not ideal or not what we want at all. At this time, we can try to use flash to eliminate the background, because when shooting with flash, the shutter speed is high, and the background outside the projection range of flash will not be displayed because of insufficient exposure. Due to the flash lighting, the foreground is correctly exposed, thus highlighting the foreground and eliminating background interference.

Another common use of flash lamps is backlighting. In this case, the best way is to fill the light in the dark to reduce the contrast of the picture. Of course, you can also reduce the light in the bright part.
