Common golden thistle, Scolymus hispanicus, flower. Above photographed with daylight and bellow showing fluorescent colours when photographed under ultraviolet light with a Baader-U Filter. This filter enables imaging in the deep UV spectral region. Some flowers have patterns that are only visible under ultraviolet light. Those surprising patterns can only be seen by the insects. While pollinating insects can see these patterns perfectly to find the nectar and pollen, the human eye cannot without some help of special photography. Portugal

Ce filtre permet une imagerie dans la région spectrale UV profonde. Certaines fleurs ont des motifs qui ne sont visibles que sous une lumière ultraviolette. Ces motifs surprenants ne peuvent être vus que par les insectes. Alors que les insectes pollinisateurs peuvent parfaitement voir ces motifs pour trouver le nectar et le pollen, l’œil humain ne peut pas faire appel à des photographies spéciales.
