Answer: I think Rupert may use an illustrative or reportage approach, but I don't know Rupert.
Explanation: "Approach" is used so vaguely and there are many different meanings to approach in photography.
• Illustrative – (In terms of subject matter, illustrative photography is difficult to define. It could centre on still life as easily as people or landscape. Jerry Uelsman sums it stating that illustrative work is photographing objects for "what else they are." In this category, photographers use whatever subjects necessary in ways that strongly illustrate a concept. This approach to photography has become popular in almost every aspect of applied art. Initially editorial work was the most common arena for illustrative work as the images had no other purpose than to illustrate the written editorial. However, it has become progressively popular in advertising, annual reports and all forms of non-media assignments such as CD covers as designers and art directors find new ways of utilizing the power of the illustrated photograph.
• Reportage – (Reportage or Photojournalism is associated to creating images in order to tell a news story of a real life event. Photojournalism is distinguished from other closely related areas of photography like documentary photography, street photography or celebrity photography by three qualities. - 1. Timeliness — the images have meaning in the context of a published chronological record of events. - 2. Objectivity — the situation implied by the images is a fair and accurate representation of the events they depict. 3. Narrative — the images combine with other news elements, to inform and give insight to the viewer or reader.
• Metaphoric - Metaphor is defined as the substitution of one idea or object with another, used to assist expression or understanding. - Examples - Manuel Alvarez Bravo
