earth-angle: So our lights have been exposed this whole time? Apologies lol
me: haha – many don’t know their real “privates” are already on display
In photography, exposure is the amount of light per unit area (the image plane illuminance times the exposure time) reaching aphotographic film or electronic image sensor, as determined by shutter speed, lens aperture and scene luminance. Exposure is measured in lux seconds, and can be computed from exposure value (EV) and scene luminance in a specified region.
same concept with sound- it’s all vibration
