He helped establish the Holography Department of the Royal College of Art, which was the first of its kind in the world, before leaving to concentrate on creating his own holographic studio. In , he co-created the first official holographic portrait of the Queen. A decade later, in another first, he made a carat gold holographic portrait miniature — inventing a brand new portrait medium in the process. This describes a photograph of a light field, or interference pattern, rather than an image formed by a lens, which, when properly lit, results in a 3D image which can be seen by the naked eye.
When I conduct high-profile shoots in London or elsewhere, such as the recent shoot of Angelina Jolie in Hollywood, I hire a convenient studio and move my dedicated equipment and cameras to it. By comparison, when in France, I have the luxury of shooting at my leisure. The flowers for my new series were both grown and shot at my home in France. In other words, a sequence of photographs is taken from slightly different points of view around the subject or scene, to later be fed into a computer and made into an image that can be read as a 3D photograph.
The initial step is achieved in a number of ways, but my preference is to move a camera under computer control along a linear rail, taking a picture every 10mm or so, with the camera rotating so it keeps pointing towards the centre of the subject. A conventional camera sits upon a rotary stage, which is itself placed on top of a two-metre-long motorised linear rail. This enables the camera to be translated smoothly at high speed and with extreme accuracy under computer control.
This is particularly important for portraits. As soon as the image sequence has been shot, it is automatically downloaded to a computer hard drive and a 3D image is presented on a large format 3D TV for viewing. Once the sequence is processed the images are combined or interlaced, again using special software, to create one single image, which is printed. The resulting print is then laminated in register to the back of a matching lenticular lens to provide the finished 3D image.
There are many websites that describe this process in far more detail than I can do here, but the technique is not difficult to master and great results can be achieved. It is far less immediate and requires much greater planning. Certain parameters are fixed, such as the distance of the camera from the subject and thus the focal length of the lens used. This can sometimes limit the types of images shot and the medium used. And, as with traditional sculpture, you must first carefully consider the dimensionality of the subject. Instead, I have used the latest lenticular imaging techniques.
True holography is a highly complex and expensive process and, despite its fundamental ability to reproduce optical reality, it can be quite limited in other ways. Many practitioners of true holography have therefore, over recent years, gravitated towards lenticular imaging. Being a stereo-photographic process, it is far simpler and cheaper. While lenticular images cannot reproduce reality as effectively as true holograms, they are nonetheless very convincing if made correctly. Lenticular lenses can be purchased from a variety of companies.
A sequence of images can be shot with a simple turntable, which is equivalent to moving a camera around a subject. Simply place a camera on a tripod and rotate the subject, taking a picture every degree or so. Written by Gary Evans.

Samenvatting Holograms have been in the public eye for over a half-century, but their influences have deeper cultural roots. No other visual experience is quite like interacting with holograms; no other cultural product melds the technological sublime with magic and optimism in quite the same way.
Samenvatting
As holograms have evolved, they have left their audiences alternately fascinated, bemused, inspired or indifferent. From expressions of high science to countercultural art to consumer security, holograms have represented modernity, magic and materialism. Their most pervasive impact has been to galvanise hopeful technological dreams.
Engineers, artists, hippies and hobbyists have played with, and dreamed about, holograms. This book explores how holograms found a place in distinct cultural settings. It is aimed at readers attracted to pop culture, visual studies and cultural history, scholars concerned with media history, fine art and material studies and, most of all, cross-disciplinary audiences intrigued about how this ubiquitous but still-mysterious visual medium grew up in our midst and became entangled in our culture. This book explores the technical attractions and cultural uses of the hologram, how they were shaped by what came before them, and how they have matured to shape our notional futures.
Today, holograms are in our pockets as identity documents and in our minds as gaming fantasies and 'faux hologram' performers. Why aren't they more often in front of our eyes?
