This book is a good one......I guess. The reason why I am not sure is that I have had this book for over a year now and I still havent managed to read it completely. Everytime I start reading it, it loses my interest after the third chapter. The authour would have been happier writing poetry about the LAB colour space. He keeps ranting on and on and on about the LAB colour space but when it comes to actually teaching you something new he does it in less than half the pages of the book. It gets to the point where the reader just goes - Ok, LAB is THE colour space to work in, now would you please stop telling me that after every other paragraph? Too much uselss information and very less practical knowledge.
