Poetry. A slim volume of minimalist verse that takes the reader on an exploration of unfamiliar terrain with the senses heightened. It is quiet and sensitive; one perceives and feels every drop, shadow and ray of light. The mood is enhanced by black and white graphics produced by three French artists--Sibylle Baltzer, Nelly Buret and Caroline Francois- Rubino--and one Greek -- Dimitris Souliotis. "THE DARK BRIGHTNESS represents a turn in John Taylor's writing. Known for his short prose evoking his childhood in Des Moines and his adult life in France, where he has long lived, Taylor is now writing short, meditative, almost 'pre-Socratic' poems arranged into sequences and focused on existential issues: a man's relationship to language (and foreign language), to nature, to his personal past, and to his future death. At the heart of this volume, with these various themes, is an attempt to reproduce essential moments when something--a phenomenon in the outer world, or a thought, an emotion, a sensation--comes into being, emerges into visibility, into awareness, something that was previously within a darkness, or was perhaps itself the darkness." --Jeremy Alden

"The effects of pure red and low color temperature white flood lighting upon completely dark adapted visual thresholds have been determined. The red light was adjusted to brightness levels which pilots have been found to use as the minimal, normal, and maximal levels for night flying. For each brightness level of the red light, a brightness was found for the low color temperature white light at which aircraft instruments were equally legible under the two lighting systems. Both a simulated instrument panel and a pure white panel were used as viewing panels. Six subjects were tested under each lighting condition. A higher brightness proved necessary with the low color temperature white light than with the pure red light in order to attain equal legibility of instruments. Both lighting systems at all brightness levels caused small increases in visual thresholds above the completely dark adapted state. When the simulated instrument panel was illuminated at the normal brightness level, thresholds after viewing low color temperature white light were 0.15 log micro-microlamberts above thresholds after viewing pure red light. This value defines the approximate sacrifice in dark adaptation which would be made if white lights, operated at low voltage, were substituted for red lights in flood lighting aircraft instruments. The white lighting would also be more visible to dark adapted enemy observers. However, the white lighting system would make colors in the cockpit appear more natural, which would facilitate such tasks as map reading. When operated at normal voltage, the white lighting system could also provide high intensity illumination for special purposes such as thunderstorm flying, very high altitude daytime flight, and simulated instrument flying with the amber hood and blue goggles."--Abstract.

This volume deals with the visual perception of lightness, brightness, and transparency of surfaces, both under minimal laboratory conditions and in complex images typical of everyday life. Each chapter analyzes the challenging problem of how a pattern of light intensities on the retina is transformed into the visual experience of varying shades of grey, transparent surfaces, and light and shadow. One important theme which unifies the group of contributions is the recognition that the perception of surface lightness is rooted fundamentally in the encoding of relative intensities of light within the retinal image, not intensities per se. A second important unifying theme is an appreciation of the multiple dimensions of the visual experience of lightness, brightness, and transparency -- people do not perceive the lightness of surfaces by discarding information concerning the light illuminating those surfaces; rather, they perceive a pattern of illumination projected onto a pattern of surface greys. The long-fascinating problems of surface lightness and color perception have become very active topics recently as a resurging interest within the visual perception community has coincided with an increasing appreciation of the centrality of these problems by the emerging machine vision community. The best of recent psychophysical work on lightness perception, as presented in this volume, will be of great interest to both of these communities. This book also marks a synthesis of old and new. A traditional, strongly Gestalt, approach that had fallen into neglect is updated in the light of new quantitative systematic methods and important later discoveries, such as the disappearance of stabilized retinal images. The book draws on such diverse approaches as Gestalt and ecological psychology, threshold psychophysics, and computational vision, advancing our understanding of the interrelations among surface color, illumination, perceived depth, shading, and transparency.
