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.
