How does the flash on the camera work?

Answer 1

The flash contains three basic parts.

First is something that produces light. Today that's almost always a flashtube, but there have been bulbs containing little pieces of magnesium foil and pans of a flammable powder called "flash powder." Underwater photographers still use flashbulbs because you can get ones that put out far more light than flashtubes are capable of.

Second is a source of power. Flashes can be powered by batteries or AC power.

And third is a capacitor. This is a component that can store electricity and discharge it all extremely quickly.

Because this needs to be semi-short let's just assume you have a battery-operated flash with a flashtube in it.

When you turn the flash on, you'll hear a little buzzing sound as the flash's power source charges the capacitor. It will store the charge until it is needed.

When your camera tells the flash to work, it will dump all the electricity in the capacitor into the flashtube. A big arc will happen inside the tube, which is filled with Xenon gas. When Xenon is exposed to this arc, it will get excited and give off a lot of light.

After this happens, the flash will recharge the capacitor and wait for you to take another flash picture.

Answer 2

Transformer uses low battery voltage to charge a capacitor, which stores a charge that reaches thousands of volts. When discharged across the terminals of the rare gas filled tube, the energy is converted to light energy whose color temperature is close to daylight (5200 K). NEVER attempt to repair your own flash. Those who have received the brunt of the discharge have been knocked right off their chair.

The first cameras used gun powder to make a flash. Then in the 1950-1960's, cameras used a flash bulb that had fine magnesium wire that burned very brightly when an electric charge was sent through it. Sometimes the bulb would explode.

Answer 3

On a disposibal camera, just don't touch it for at least 10 minutes. On a regular camera, (one you charge) there should be a menu, and look for either flash, or a lightning bolt maybe. I hope I helped!! :))

Answer 4

The flash memory is what holds the photos. A digital camera does not use film and has to have some other place to store the photos. Since the picture is digital, then it needs to be stored on some sort of memory.

Answer 5

It's an ordinary lightbulb, that is powered when the shutter button is pressed.

Answer 6

The flash on a Olympus camera is an external flash unit. It can be used in a auto fashion just like the built in flashes on regular point and shoot camera's.
