"Vitamin Ph" provides a third dose of visual stimulation and vital information, following on from the successes of Vitamin P and Vitamin D. Similar in concept, scope and structure, "Vitamin Ph" presents, in A to Z order, the work of 121 international artists. This up-to-the-minute survey focuses on global developments in art photography and the use of the medium by contemporary artists. 78 nominators worldwide have identified living artists who have made a fresh and innovative contribution to recent international photography. These selections will be accompanied by a 5000 word introductory text by TJ Demos, aiming to explore ideas relevant to contemporary photography with reference to the works included in the book. In addition, the work of each photographer/artist is introduced by a short commissioned text of approximately 500 words. All works reproduced in the book use photography as their primary medium or source material, whether or not they then develop into or merge with other media. Extending beyond the parameters of straight photography to encompass sculptural, painterly and filmic elements, "Vitamin Ph" explores the medium in an expanded sense. The artists represented have emerged, or re-emerged, in the last five years to create a distinctive body of new work. "Vitamin Ph" aims to contribute to international debates on contemporary photography whilst providing an accessible overview and concise reference book.
