What does the flash do on a camera?
The flash is a device that emits light momentarily. You can use the flash’s light to compensate for the lack of brightness when shooting in dimly lit situations like indoors or night scenes.

What causes artifacts in video?

Does flash on camera make you look worse?
Well it’s not camera flash. As you can see from photo 4, camera flash typically only makes things worse by creating brighter bright spots (called “hot spots”) that make the subject look sweaty or greasy without totally fixing the shadow problem. A sunny outdoor picture doesn’t set things right, either.
Is on camera flash bad?
Yes, there are ways that extremely bright lights can damage someone’s eyes. However, photography flashes, at least for the vast majority of people in the vast majority of circumstances, aren’t harmful. There is something called “flash blindness,” when the retina gets too much light and you can’t see clearly.
Do you need flash for outdoor photography?
Daytime Outdoors The majority of the time, shooting outdoors doesn’t require firing a flash, even in the shade, as the sun does most of the hard work for you. If you have a subject that you can move, try to get them to change their positioning so that the sun hits them from the side rather than from behind.
