This is a guide to maximizing the color quality of your images using Photoshop. Published in 2004 by Amherst Media, known as a publisher of photography books. Title is: "Color Correction and Enhancement with Adobe Photoshop. 2004. Michelle Perkins.
It is one I used in learning how to digitally prepare and at times improve the output of my images (mostly all film, darkroom printing then digital printing). There are some places in the book where I have highlighted text. Short of that, pages are mint condition and the covers with just a few scratches and crimps on the edges of the dovers. Very few.
The book teaches what color modes are and channels, how to analyze black point, white point, neutrals, skin tones and other characteristics of your images. So a lot of special skills, especially too if you photograph people, weddings and do school photography. Also how to use levels, curves, color-correction tools and much much more. Great reference and teaching tool. It will improve your photogrpahs.
