Many natural materials glow under ultraviolet light, revealing hidden colors and patterns that are invisible under normal illumination. This sub-gallery showcases the fluorescence of flowers, fungi, lichen, plants, cacti, and minerals, each responding to UV light in a unique way. The vivid glow of flowers and plants comes from naturally occurring compounds, while fungi and lichen display eerie luminescence under UV illumination. Fluorescent minerals, on the other hand, owe their glow to the way their crystal structures interact with ultraviolet light, producing strikingly intense colors. These images highlight the hidden beauty of fluorescence in the natural world, transforming familiar subjects into glowing, otherworldly forms.
