Fill light and flash
The information comes from:Internet Posted on:2021-06-08
Flash, as the name suggests, can only flash for a moment.
At present, the mainstream flash is xenon lamp, which is widely used in all kinds of cameras, as well as independent professional flash. Xenon flash is not widely used in mobile phones. Once it is used, it is bound to be a selling point for hype. It's not hard to find out if you pay a little attention to it.
The others are led fill lights. In principle, there is no LED flash, because there is no need to make the LED light source in the form of instant light, and there are also technical difficulties.
Led fill light can be continuously illuminated for a period of time, because it doesn't need to be on for a long time when taking pictures, which is generally about 1 second. Some businesses also call it "flash" (in fact, the lighting time of xenon flash is less than 1 / 60).
From the brightness point of view, the brightness of LED fill light for mobile phone is similar to that of micro LED flashlight on the market. Generally, it can illuminate the scenery within 3 meters. If the shooting quality is guaranteed, it is better not to exceed 2 meters. And xenon lamp camera mobile phone can usually use about 5 meters.
Double LED lamp, which means one more bulb, is more or less brighter, but it still can't be compared with xenon lamp.
But led light also has its own advantages, that is, it can continue to illuminate like a flashlight, and it can also play a role in shooting video. Xenon lights are useless for video.
