Lady's Slipper

In Britain, the exotic-looking Lady's Slipper orchid grows in the wild only at a handful of limestone grassland sites in north-west England. I photographed this flower just as the early morning sun began to catch it. Using a 300mm lens with extension tubes enabled close control of depth of field. A wide aperture gives a pleasingly diffuse background and to get the flower sharp I made five images with identical compositions but different points of focus. I combined the five shots using focus stacking software to give a finished image that has good depth of field for the flower but retains an out of focus background.
