About this image

Time-lapse sequence showing the opening of a flower of a Glory Lily (Gloriosa superba). This clearly illustrates how the petals enlarge, flex upwards and change colour as the flower opens. This exposes the stamens and stigma so that butterfly pollinators can make contact with them. These images are part of an ongoing project on floral structure and pollination mechanisms, which Heather Angel is undertaking for the Royal Botanic Gardens, Kew. The images were captured using a Nikon D3 camera and 105mm macro lens with illumination from two SB900 electronic flash units. Separate exposures were later combined in an image editing program.
