Starting Electronics, Third Edition Starting Electronics, Third Edition

Год издания: 

This book originated as a collection of feature articles, previously published as magazine articles. They were chosen for publication in book form not only because they were so popular with readers in their original magazine appearances but also because they are so relevant in the field of introductory electronics — a subject area in which it is evermore difficult to find information of a technical, knowledgeable, yet understandable nature. This book is exactly that. Since its original publication, I have added significant new material to make sure it is all still highly relevant and up-to-date.

Photoshop CS2 Raw: Using Adobe Camera Raw, Bridge, and Photoshop to Get the Most Out of Your Digital Camera 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.
