Secrets of exposure revealed, with a bonus color checker card included Exposure is the number one topic that digital photographers want to know about. This full-color book fits in your camera bag and provides all the information you need on this very important aspect of digital photography. Exposure involves combining ISO, aperture, and shutter speed in different variations to accomplish your vision of the perfect image. Exposure Digital Field Guide takes you through the complex techniques of good exposure, taking you from hobbyist to serious amateur photographer. Explains how to adjust shutter speed and aperture to control the amount of light hitting the camera's light sensor Teaches you how to «see the light» for the perfect exposure Helps you gain confidence as you move from automatic controls into manipulating the elements of exposure for specific results Packed with stunning full-color photographs to illustrate what you can achieve Provides suggested settings for various shooting situations and subjects Includes a tear-out color checker card to help you maintain true color Fits in your camera bag for ready reference in the field Exposure Digital Field Guide helps you master one of the most complex and intricate elements of digital photography.

Nowadays approximately 6 billion people use a mobile phone and they now take a central position within our daily lives. The 1990s saw a tremendous increase in the use of wireless systems and the democratization of this means of communication. To allow the communication of millions of phones, computers and, more recently, tablets to be connected, millions of access points and base station antennas have been extensively deployed. Small cells and the Internet of Things with the billions of connected objects will reinforce this trend. This growing use of wireless communications has been accompanied by a perception of risk to the public from exposure to radio frequency (RF) electromagnetic field (EMF). To address this concern, biomedical research has been conducted. It has also been important to develop and improve dosimetry methods and protocols that could be used to evaluate EMF exposure and check compliance with health limits. To achieve this, much effort has was made in the 1990s and 2000s. Experimental and numerical methods, including statistical methods, have been developed. This book provides an overview and description of the basic and advanced methods that have been developed for human RF exposure assessment. It covers experimental, numerical, deterministic and stochastic methods.

Everyone, whether they like it or not, is exposed to electromagnetic fields, most of the time, at very low levels. In this case, they are inconsequential, but they can cause adverse health effects when they become intense enough. This topic is complex and sensitive. Covering frequencies from 0 Hz to 300 GHz, Human Exposure to Electromagnetic Fields provides an overview of this vast topic. After a reminder of the concepts of electromagnetic fields, the author presents some examples of sources of radiation in daily life and in the industrial or medical sectors. The biophysical and biological effects of these fields on the human body are detailed and the exposure limits are recalled. The exposure assessment and the implementation of the appropriate regulation within companies are also covered. Technically and practically, this book is aimed at people with a scientific background, risk prevention actors, health physicians, especially occupational doctors, and equipment designers.
