In the 90s, and up until cell phone cameras were a big thing, I remember some family members having cameras with rather large flash modules on top and it would make a weird noise once the flash goes off after taking a picture. Some smaller flash capable cameras would make the sound also.
In: Technology
Back in the day, cameras needed extra light to take pictures when it was dark. Those things on top were flash units. They worked like bright flashlights, but instead of turning on instantly, they needed a moment to charge up. When you took a picture, they released all their energy in a bright burst of light. That “weird noise” you heard was the sound of the flash charging up and then releasing all its energy.
