Designing for Digital Reading

Reading is a complex human activity that has evolved, and co-evolved, with technology over thousands of years. Mass printing in the fifteenth century firmly established what we know as the modern book, with its physical format of covers and paper pages, and now-standard features such as page numbers, footnotes, and diagrams. Today, electronic documents are enabling paperless reading supported by eReading technologies such as Kindles and Nooks, yet a high proportion of users still opt to print on paper before reading. This persistent habit of «printing to read» is one sign of the shortcomings of digital documents – although the popularity of eReaders is one sign of the shortcomings of paper. How do we get the best of both worlds?
The physical properties of paper (for example, it is light, thin, and flexible) contribute to the ease with which physical documents are manipulated; but these properties have a completely different set of affordances to their digital equivalents. Paper can be folded, ripped, or scribbled on almost subconsciously – activities that require significant cognitive attention in their digital form, if they are even possible. The nearly subliminal interaction that comes from years of learned behavior with paper has been described as lightweight interaction, which is achieved when a person actively reads an article in a way that is so easy and unselfconscious that they are not apt to remember their actions later.
Reading is now in a period of rapid change, and digital text is fast becoming the predominant mode of reading. As a society, we are merely at the start of the journey of designing truly effective tools for handling digital text.
This book investigates the advantages of paper, how the affordances of paper can be realized in digital form, and what forms best support lightweight interaction for active reading. To understand how to design for the future, we review the ways reading technology and reader behavior have both changed and remained constant over hundreds of years. We explore the reasoning behind reader behavior and introduce and evaluate several user interface designs that implement these lightweight properties familiar from our everyday use of paper.
We start by looking back, reviewing the development of reading technology and the progress of research on reading over many years. Drawing key concepts from this review, we move forward to develop and test methods for creating new and more effective interactions for supporting digital reading. Finally, we lay down a set of lightweight attributes which can be used as evidence-based guidelines to improve the usability of future digital reading technologies. By the end of this book, then, we hope you will be equipped to critique the present state of digital reading, and to better design and evaluate new interaction styles and technologies.

Photoshop CS2 Raw: Using Adobe Camera Raw, Bridge, and Photoshop to Get the Most Out of Your Digital Camera
Автор: Aaland Mikkel
Год издания:
The RAW file format is the uncompressed data file captured by a digital camera's electronic sensor. When your camera saves an image in RAW format, settings like white balance, sharpening, contrast and saturation are not applied to the image but are saved instead in a separate header. Because RAW files remain virtually untouched by in-camera processing, they are essentially the digital equivalent to exposed but undeveloped film.
This makes RAW an increasingly popular format with amateur and professional digital photographers, because it affords greater flexibility and control during the editing process-if you know how to work with RAW files.
Most digital camera manufacturers supply their own software for converting RAW data, as do some third party vendors. Increasingly, however, the RAW converter of choice is a plug-in included in the latest version of Adobe Photoshop, the most popular and widely-used digital image editing tool in the world. Adobe Photoshop CS2 is emerging as the best place to edit RAW images, and the best way to master this new format is with Photoshop CS2 RAW.
An important book dedicated to working with RAW in Photoshop, this comprehensive guide features a unique design that helps readers grasp the subject through visual instruction and prompts. The entire RAW process is explored, from shooting to using the Adobe plug-in converter and new Bridge navigation software. The primary focus of Photoshop RAW is, as the title suggests, Photoshop editing technique: automating RAW workflow, correcting exposures, extending exposure range, manipulating grayscale and working with the new DNG (Digital Negative) open standard that Adobe supports.
Presented by photographer Mikkel Aaland, a pioneer of digital photography and author of eight books, including O"Reilly"s Photoshop for the Web and the award-winning Shooting Digital, Photoshop CS2 RAW investigates and instructs in an accessible visual style. Required reading for professionals and dedicated photo hobbyists alike.
