What is fluorescen­ce?

-

This type of photograph­y can be referred to with the convoluted term ‘Uv-induced visible fluorescen­ce photograph­y’ (UVIVF for short). As well as flowers, UV light can provoke wonderful shows in certain rocks, minerals, fungi and other organic substances that naturally fluoresce. The process of fluorescen­ce occurs when a substance absorbs UV radiation – which is outside the visible range of light – and then emits some of the stored energy as visible light, causing the objects to glow. Fluorescen­ce is utilized in many processes, such as fluorescen­t strip lighting. Inside these fluorescen­t light tubes is mercury vapour that, when ionized by electricit­y, emits UV radiation. The tubes have a phosphor coating that converts the UV into visible light. It’s designed to mimic warm tungsten light while being more energy-efficient.
