I consider this to be an excellent text covering a large spectrum of imaging in general - a good work and reference book but I have one reservation - the spiral plastic binding is too small and will not allow the book to open without damaging the holes where the binding is inserted - in order to turn a page without tearing the binding holes one must stand the book on its binding edge and then open to the desired page. I had to remove the existing spiral binding and have a larger one installed by a print shop.
