Overview of photography and perspective

As an applied technology, photography was born and grew up in modern times, and its rapid development can be said to be changing with each passing day. Especially after digital intervention in photography, the technical means of photography has become more diversified and marginalized. Many theories and norms of photography technology, once regarded as the golden rule, have gradually faded or even faded out of the photography world. And those technical categories that are directly related to human vision are inseparable from the final visual effect of the image and will not change because of the changes in the previous image capture and materialization methods. Perspective is a typical example. Whether using traditional photochemical technology to obtain images, using digital microelectronics technology to obtain images, or even using computer programming technology to design and make images, once the images become photos or pictures, we can't get rid of the perspective principle of human perception. For this reason, when photography technology is fully developed, the research on the principle and application of photographic perspective has not been lost, but has become more in-depth, subtle and creative.

This book is such a work that should meet the needs of the high-tech photography era. It can be said that no matter what kind of camera you have in your hand and what kind of post-production means you use to get photos, you will find wise guidance in this book quickly and satisfactorily on the issues of framing perspective, optimizing images and optimal composition.

In addition to the precise principle explanation, this book also highlights the combination of perspective law and shooting practice, and consciously emphasizes various special norms of fine photography. It should be said that this practice is of special significance to the present situation of photography industry in China. For half a century, China's photography, whether it is the dominant news photography or the most popular portrait photography in photo studios, is still extensive from the technical level. The creative concept, design pursuit and even all the operation methods of photos are limited to meet the general needs, and the quality is poor. However, in the market economy environment, especially in the increasingly obvious globalization background after China's entry into WTO, this extensive technology has completely failed to meet the needs of economic and cultural development and must be eliminated. This requires the timely introduction and popularization of new fine photography technical specifications. This book should be said to be a step ahead, and it has gained a lot in this respect.

In particular, there is a chapter in the book that introduces the moving axis and perspective of large cameras. This is the scientific research achievement that several authors have devoted themselves to for many years. In order to make this achievement realize social benefits as soon as possible, they unreservedly dedicated their research experience to their photography colleagues. Large-scale professional cameras are an indispensable infrastructure for high-precision, large-format, complex and creative fine photography, especially commercial advertising photography, which has gradually become popular in China. But how to give full play to the inherent potential of this special camera is still unclear to many people. I believe that the publication of this book will definitely save beginners or colleagues in the industry a lot of time to re-explore, and soon reach a handy and comfortable position.

In the field of photography, perspective is both a starting point and a conclusion point. It is the embodiment of natural laws and the creative world of human beings. This book is not limited to lens and shooting, but also absorbs other technical methods and their different effects on perspective, such as Chinese painting-style scattered perspective, color perspective, tone perspective and so on, and makes an enlightening exposition.
