Le marché de la photographie est éclaté en de nombreux segments aux fonctionnements très disparates. Cette diversité s’accompagne d’une grande variété dans les statuts et les modes de rémunération, les photographes pouvant être payés, selon les cas, en droits d’auteur, salaires, bénéfices industriels et commerciaux, bénéfices non commerciaux. La restructuration des marchés autour de nouveaux leaders (Getty, Corbis, Jupiter…), suite à la révolution numérique, a fragilisé les agences d’auteurs et réduit le pouvoir de négociation des |

photographes au sein de la filière. Elle s’est accompagnée du développement de nouvelles pratiques comme la vente de photographies libres de droits. Très rentables pour les diffuseurs, en termes de coûts de transaction comme en termes de prix d’achat, ces pratiques précarisent les photographes et sapent les fondements du droit d’auteur, tant dans son versant patrimonial que moral. Les revenus de la mode et de la publicité et le développement récent d’un marché des tirages photographiques, marchés au demeurant très sélectifs, ne suffisent pas à compenser l’érosion des revenus des photographes. La porosité croissante des marchés favorise en outre des arbitrages entre droits d’auteur et salaires, en raison de taux de cotisations sociales très inégaux, fragilisant les droits sociaux des photographes. Enfin, les revenus issus de la gestion collective demeurent embryonnaires malgré des perspectives de développement prometteuses. The photography market is split into a large number of segments, all with their own different manners of operating. This diversity goes along with a wide variety of statutes and methods of remuneration. Photographers can be paid royalties, wages, business returns or professional fees, as the case may be. The restructuring of the market under new leaders (Getty, Corbis, Jupiter, etc.) in the wake of the digital revolution has crippled the agencies and sapped the photographers’ negotiating power within the trade. It is… |

Sommario/riassunto |
|
The main objective of this book is to give a broad unified introduction to the study of dimension and recurrence in hyperbolic dynamics. It includes the discussion of the foundations, main results, and main techniques in the rich interplay of four main areas of research: hyperbolic dynamics, dimension theory, multifractal analysis, and quantitative recurrence. It also gives a panorama of several selected topics of current research interest. More than half of the material appears here for the first time in book form, describing many recent developments in the area such as topics on irregular sets, variational principles, applications to number theory, measures of maximal dimension, multifractal nonrigidity, and quantitative recurrence. All the results are included with detailed proofs, many of them simplified or rewritten on purpose for the book. The text is self-contained and directed to researchers as well as graduate students that wish to have a global view of the theory together with a working knowledge of its |

main techniques. It will also be useful as as basis for graduate courses in dimension theory of dynamical systems, multifractal analysis, and pointwise dimension and recurrence in hyperbolic dynamics. |
