Participatory IT Design: Designing for Business and Workplace Realities
by Keld Bodker Finn Kensing Jesper SimonsenThe goal of participatory IT design is to set sensible, general, and workable guidelines for the introduction of new information technology systems into an organization. Reflecting the latest systems-development research, this book encourages a business- oriented and socially sensitive approach that takes into consideration the specific organizational context as well as first-hand knowledge of users' work practices and allows all stakeholders--users, management, and staff--to participate in the process. Participatory IT Designis a guide to the theory and practice of this process that can be used as a reference work by IT professionals and as a textbook for classes in information technology at introductory through advanced levels. Drawing on the work of a ten-year research program in which the authors worked with Danish and American companies, the book offers a framework for carrying out IT design projects as well as case studies that stand as examples of the process. The method presented in Participatory IT Design--known as the MUST method, after a Danish acronym for theories and methods of initial analysis and design activities--was developed and tested in thirteen industrial design projects for companies and organizations that included an American airline, a multinational pharmaceutical company, a national broadcasting corporation, a multinational software house, and American and Danish universities. The first part of the book introduces the concepts and guidelines on which the method is based, while the second and third parts are designed as a practical toolbox for utilizing the MUST method. Part II describes the four phases of a design project--initiation, in-line analysis, in-depth analysis, and innovation. Part III explains the method's sixteen techniques and related representation tools, offering first an overview and then specific descriptions of each in separate sections.

Photoshop Blending Modes Cookbook
by John BeardsworthLayer blending modes have been part of Photoshop for years, but because they're not easy to understand at first glance, this immensely useful feature tends to get overlooked. Photoshop Blending Modes Cookbook for Digital Photographers is the only recipe-format book that covers blending modes specifically for digital photographers. The book covers: Changing hue, saturation, luminosity, and color Correcting basic color shifts Repairing highlights Sharpening or softening focus Adjusting lighting for subtle or dramatic effects Controlling contrast Creating surface effects and textures Adding interest to landscapes and urban scenes Enhancing portraits of children and adults Simulating graphics arts techiques and much more.

There are over 20 blending modes in Photoshop CS2, which range from those which darken and lighten images (such as Darken, Multiply, Lighten, and Screen) to modes that increase contrast (such as Overlay and Hard Light) and adjust color (such as Hue, Color. Luminosity, and Saturation). In addition to covering each blending mode in detail, John Beardsworth, a London-based photographer and author, takes the reader through a whole collection of recipes that demonstrate how to use blending modes alone or in combination to fix problem photos, add subtle effects, and create dramatic images that are truly unique. With clear, step-by-step instructions, real-world projects, an easy-to-follow format, and hundreds of full-color examples, Photoshop Blending Modes Cookbook for Digital Photographers is shows you how to use blending modes to achieve a wide range of image adjustments and special effects-without having to first learn everything there is to know about Photoshop.
Photoshop Filter Effects Encyclopedia
by Roger PringAdobe Photoshop has become the tool of choice for professional photographers, designers, and amateur enthusiasts. But it's a complex application with many features-and scant information on how to use them to best advantage. A case in point: there are 100 built-in filters in Photoshop, designed to enable the user to easily make subtle or dramatic image adjustments, and there is very little online help available with the application, and no printed manual. Users can spend hours trying to use filters effectively-an inefficient and often frustrating way to work. In Photoshop Filter Effects Encyclopedia , author and educator Roger Pring explains and decodes the settings of every filter that Photoshop CS2 has to offer, from Artistic filters such as Colored Pencil, Cutout, and Watercolor to Stylize filters like Bevel, Emboss, and Extrude. And, unlike many reference books that give you a lot of information you'll never need, it is filled with easy-to-follow, step-by-step, practical recipes for creating truly amazing effects, such as: Creating selective focus Simulating motion blur Adding special lens and filter effects Working with tone and color Creating dramatic solarized and posterized images Working with artificial lighting Simulating textures Creating multi-layered images and photomontages Reproducing graphic arts effects and much more. The best part is that you don't have to be a Photoshop expert to create sophisticated, professional-looking results-the recipes take the guesswork out of the process, so you can work quickly and efficiently. Packed with hundreds of full-color photographs, clearly written instructions, and practical tips, this book is the ultimate, no-nonsense Photoshop CS2 Filters reference for creative photographers, designers, and artists.

A Practical Guide to Security Assessments
by Sudhanshu KairabThe modern dependence upon information technology and the corresponding information security regulations and requirements force companies to evaluate the security of their core business processes, mission critical data, and supporting IT environment. Combine this with a slowdown in IT spending resulting in justifications of every purchase, and security professionals are forced to scramble to find comprehensive and effective ways to assess their environment in order to discover and prioritize vulnerabilities, and to develop cost-effective solutions that show benefit to the business.

In addition to the methodology, the book includes an Appendix that contains questionnaires that can be modified and used to conduct security assessments. This guide is for security professionals who can immediately apply the methodology on the job, and also benefits management who can use the methodology to better understand information security and identify areas for improvement.
