KK: /ˈfoʊtəˌflʌd/
A type of electric lamp that gives off a strong, steady light, used mainly for photography.
The photographer used a photoflood to ensure the subject was well-lit during the shoot.
Photoflood → It is formed from "photo-" (from Greek "phōs", meaning light) and "flood" (from Old English "flōd", meaning a flowing or stream). The word "photoflood" refers to a strong burst of light, akin to a flood of light illuminating a scene.
Think of 'light' ('photo-') pouring in like a 'flood' — that's why photoflood means a burst of light.
