Real World Photoshop 7 is an ultimate digital dark room technique book for Photoshop 7 users. The largest part of the book is dedicated to dark room techniques, but a good part of the book covers such things as getting the best scans, creating effects, saving for the web, making half-tones, etc.
They cover lots of issues that help me understand WHY I might want to do something a certain way. Such as, the differences between RGB, CMYK and LAB color. When I bring a digital photo into Photoshop, I almost always feel a need to adjust it, fix the levels, etc. Fooling with the levels usually causes a color shift. To avoid that, they explain how to change the mode from RGB to LAB color, and then apply the levels command to the L (luminance) channel, leaving the color untouched. I can change the mode back to RGB afterwards, if I want.
In discussing color correction, they talk about fixing the neutrals so the rest will follow and explain that in Photoshop's RGB mode, it automatically calculates the amount of CMYK to produce neutrals, but in CMYK mode, you have to manually fill in the percentages. The section on color correction is incredible.
They discuss printing from Photoshop 7, the issue of different file formats and which to use when; the Rule of 16; which settings take precedence over others, and much more.
The book is well laid out, with an easy to follow structure. Several light bulbs spontaneously illuminated for me while reading this book. This book is useful to new Photoshop users and for seasoned photographers who have past experience with Photoshop but like to keep a reference of new features.
