Photographer Robert Llewellyn applies a highly-sophisticated photographic technique — which he combines with the most advanced camera equipment — when capturing his wildlife images.
When photographing flowers and seeds, Bob combines his knowledge of engineering and contemporary technology to create images in full focus with an alternative method using innovative digital camera technology that provides for an unlimited depth of field. He mounts small sections of live samples below a vertically-mounted, motorized camera. In travelling just an eighth of an inch the camera captures two dozen frames, which the computer then assembles into a composite picture of the sharpest areas of each image. Every bud, flower, and leaf is photographed up to 50 times at various distances. The final work is a composite of the sharpest areas of each picture, resolved by software and computer. The resulting photographs have a "hyper-real clarity" which circumvents the limitations of the magnifying camera lens.
"To make the image sharp from top to bottom, I used a technique called "focus stacking". I would put the seeds on a glowing light table and do a series of photographs at different focus points from top to bottom, overlapping the sharp parts. I then loaded the images into stacking software, which rendered one image that was perfectly sharp." — Robert Llewellyn
Bob uses a Canon 5DS R for most of his work, and a Canon 5D Mark IV high-speed camera for photographing wildlife. He deploys over a dozen different lenses, from a 2,000mm to a 10x microscopic lens. To capture wide landscapes, he takes multiple panoramic images with a 14mm lens, then "stitches" the shots together into a single panorama.
