Eli5: Why does a camera have to flash and time it perfectly when it takes a picture? Can’t the light just stay on?
In: 4956
The light is extremely bright. The battery of a camera can’t output that much power and have to charge up a capacitor over time and then release the energy all at once. The lightbulb could also burn out of it was powered continuously. Maybe today we can have more powerful lights with LEDs, but they would take up too much space and not fit in the camera body.
