Above: Growing Concerns 11 by Almudena Romero
London based artist Almudena Romero makes art using chlorophyll printing. Chlorophyll printing uses natural pigment changes occurring in reaction to natural sunlight. See more from the artist via Art the Science:
To make a chlorophyll print one need to let a leaf receive an extraordinary amount of sunlight so it changes some of its pigments from green to yellow. Most leaves have a variety of pigments that can absorb and release energy from a wide range of wavelengths. These are the chlorophyll, carotenoid, and anthocyanin pigments.
Chlorophyll pigments, the green ones, absorb UV and visible light and reflect back green light. These are the main pigments active in photosynthesis and they can convert light energy into chemical energy. However, they do not help to release any excess, so if the plant receives too much sunlight, only carotenoid pigments can intervene.
