Theory And Practice Of Perspective

Leonardo da Vinci declared that the first lessons for all aspiring artists should involve perspective, and this authoritative guide assists artists at all levels in following the master's advice. Its scores of concise chapters cover a vast range of subjects, offering a comprehensive view of one of art's most difficult challenges: the accurate re-creation of natural perspective. Discussions of theory encompass definitions, both scientific and informal; the horizon and the points of sight and distance; and rules and conditions of perspective. The majority of the text examines the practice of perspective, featuring instruction on how to reproduce shape, distance, proportion, shade, shadow, reflection, and other aspects that endow two-dimensional works with lifelike qualities. More than 300 illustrations and diagrams make this an exceptionally clear and thorough treatment and an essential guide for students of art, architecture, and design.

It is much easier to understand and remember a thing when a reason is given for it, than when we are merely shown how to do it without being told why it is so done; for in the latter case, instead of being assisted by reason, our real help in all study, we have to rely upon memory or our power of imitation, and to do simply as we are told without thinking about it. The consequence is that at the very first difficulty we are left to flounder about in the dark, or to remain inactive till the master comes to our assistance.Now in this book it is proposed to enlist the reasoning faculty from the very first: to let one problem grow out of another and to be dependent on the foregoing, as in geometry, and so to explain each thing we do that there shall be no doubt in the mind as to the correctness of the proceeding. The student will thus gain the power of finding out any new problem for himself, and will therefore acquire a true knowledge of perspective.

Perspectives on Place provides an inspiring insight into the territory of landscape photography. Using a range of historic and contemporary examples, Alexander explores the rich and diverse history of landscape photography and the many ways in which contemporary photographers engage with the landscape and their surroundings.Bridging theory and practice, this book demonstrates how mastering a variety of different photographic techniques can help you communicate ideas, explore themes, and develop more abstract concepts. With practical guidance on everything from effective composition, to managing challenging lighting conditions and working with different lenses and formats, you’ll be able to build your own varied and creative portfolio.Each chapter concludes with discussion questions and an assignment, encouraging you to explore key concepts and apply different photographic techniques to your own practice. Richly illustrated with images from some of the world’s most influential photographers, Perspectives on Place will help you to explore the visual qualities of your images and represent your surroundings more meaningfully.

George Adolphus Storey Book First The Necessity of the Study of Perspective to Painters, Sculptors, and Architects LEONARDO DA VINCI tells us in his celebrated Treatise on Painting that the young artist should first of all learn perspective, that is to say, he should first of all learn that he has to depict on a flat surface objects which are in relief or distant one from the other; for this is the simple art of painting. Objects appear smaller at a distance than near to us, so by drawing them thus we give depth to our canvas. The outline of a ball is a mere flat circle, but with proper shading we make it appear round, and this is the perspective of light and shade. 'The next thing to be considered is the effect of the atmosphere and light. If two figures are in the same coloured dress, and are standing one behind the other, then they should be of slightly different tone, so as to separate them. And in like manner, according to the distance of the mountains in a landscape and the greater or less density of the air, so do we depict space between them, not only making them smaller in outline, but less distinct.' Sir Edwin Landseer used to say that in looking at a figure in a picture he liked to feel that he could walk round it, and this exactly expresses the impression that the true art of painting should make upon the spectator. There is another observation of Leonardo's that it is well I should here transcribe; he says: 'Many are desirous of learning to draw, and are very fond of it, who are notwithstanding void of a proper disposition for it. This may be known by their want of perseverance; like boys who draw everything in a hurry, never finishing or shadowing.' This shows they do not care for their work, and all instruction is thrown away upon them. At the present time there is too much of this 'everything in a hurry', and beginning in this way leads only to failure and disappointment. These observations apply equally to perspective as to drawing and painting. Unfortunately, this study is too often neglected by our painters, some of them even complacently confessing their ignorance of it; while the ordinary student either turns from it with distaste, or only endures going through it with a view to passing an examination, little thinking of what value it will be to him in working out his pictures. Whether the manner of teaching perspective is the cause of this dislike for it, I cannot say; but certainly most of our English books on the subject are anything but attractive. All the great masters of painting have also been masters of perspective, for they knew that without it, it would be impossible to carry out their grand compositions. In many cases they were even inspired by it in choosing their subjects. When one looks at those sunny interiors, those corridors and courtyards by De Hooghe, with their figures far off and near, one feels that their charm consists greatly in their perspective, as well as in their light and tone and colour...

Recent decades have seen a growing emphasis, in a number of professional contexts, on acknowledging and acting on the views of children. This trend was given added weight by the UN Convention on the Rights of the Child, ratified in 1990. Today, seeking the perspective of the child has become an essential process in all sorts of tasks, from framing new legislation to regulating professions. This book answers the fundamental question of what it is that constitutes a ‘child perspective’, and how this might differ from the perspectives of children themselves. The answers to such questions have important implications for building progressive and developmental adult-child relationships. However, theoretical and empirical treatments of child perspectives and children’s perspectives are very diverse and idiosyncratic, and the standard reference work has yet to be written. Thus, this work is an attempt to fill the gap in the literature by searching for and defining key formulations of potential child perspectives within parts of the so-called ‘new child paradigm’. This has been derived from childhood sociology, contextual-relational developmental psychology, interpretative humanistic psychology and developmental pedagogy. The highly experienced authors develop a comprehensive professional child perspective paradigm that integrates recent theory and empirical child research. With its clear presentation of underlying theories and suggested applications, this book illustrates a child-oriented understanding of specific relevance to both child-care and preschool educational practice.

This book undertakes a general framework within which to consider the complex nature of the writing task in English, both as a first, and as a second language. The volume explores varieties of writing, different purposes for learning to write extended text, and cross-cultural variation among second-language writers. The volume overviews textlinguistic research, explores process approaches to writing, discusses writing for professional purposes, and contrastive rhetoric. It proposes a model for text construction as well as a framework for a more general theory of writing. Later chapters, organised around seventy-five themes for writing instruction are devoted to the teaching of writing at the beginning, intermediate, and advanced levels. Writing assessment and other means for responding to writing are also discussed. William Grabe and Robert Kaplan summarise various theoretical strands that have been recently explored by applied linguists and other writing researchers, and draw these strands together into a coherent overview of the nature of written text. Finally they suggest methods for the teaching of writing consistent with the nature, processes and social context of writing.

This book focusses on the theory and application of ‘time perspective theory’. Time perspective can be an important factor in determining psychological well-being and the way we see our world and others around us. The unique contemporary nature of this theory’s evolution has spurred great interest over the last 20 years. The editors responded to this interest by bringing together contributors across a multitude of subjects and perspectives to facilitate an unprecedented discussion on the topic; covering areas such as financial health, psychotherapy across adulthood and old age, prenatal past, metacognition, community and change, fear of crime and intrinsic motivations. The interdisciplinary nature of this project makes it of interest to a wide cross-section of academics and practitioners including psychologist, social workers, criminologists and anyone who has or wishes to adopted time perspective theorization to assist them in their understanding.

The first book in the DARG series,Development as Theory and Practice provides the only student textbook which addresses broad contemporary perspectives and debates on development and development cooperation. It introduces the notions of development and what it means from different perspectives i.e. from the point of view of academics in the wake of the New World Order, regional specialists detached from the field, Third World students of development, and development practitioners. The second part of the book focuses on development aid and examines the changing relationship between donors and recipients, and the effects of these relationships on the wider communities in these countries, and current re-evaluations of aid in principle and practice. Development as Theory and Practice is an ideal course text for advanced undergraduate and postgraduate courses in development aid as part of degree programmes in Development Studies, Geography, Politics, Sociology and Anthropology. It will also be of interest to researchers and development practitioners and professionals.
