THE MISSION
Light paint a flower with a UV torch for glowing plant photographs
Time needed One hour
Skill level Intermediate
Kit needed
• Tripod
• UV torch
• ZWB2 filter
• Safety glasses
Ultraviolet light can have a dramatic effect on flowers by revealing glowing colours and details unseen by the naked eye. Just outside the visible spectrum of light, UV causes phosphors in certain substances and surfaces to store up energy which is then released as light.
A phosphor is something that emits visible light when activated by UV radiation, like your white T-shirt and teeth under black lights at a disco.
But those sort of disco lights won’t cut it here. The problem is they produce a lot of visible light. They work great on things like T-shirts and glowing makeup because these surfaces have strong UV reflectance. But with flowers, the UV reflectance is much weaker. Instead, we need a more concentrated UV beam in the form of a UV torch.
