Giant, determined flower stretching towards the night sky on Vernon Street, Dublin 8
Images of flowers taken by photographer Craig Burrows using a relatively unknown process known as UVIVF (ultra violet induced visible fluorescence).
Burrows illuminates the flowers with a high intensity LED filtered to transmit only UV and infrared which the plants absorb, releasing visible light in the form of vivid colours not perceptible under normal viewing conditions.
