Query: Not very useful. Portrait style is dated. Digital is not mentioned.

Time goes fast and before you even realize information, tips, secrets regarding graphic arts -including photography- can be obsolete. This book is good if read back in the '80s. The style for protraits is out of current trends (meaning what comsumers would buy). If you plan to do business in photography, this is NOT a book for you.Aperture priority in some photos are wrongly used. Example: the girls at the gate with a cute basket of flowers. That is probably a 5.6 aperture. The point of focus (sharpness) fell on the fence! instead of girls faces or flowers. If soft focused is the point, you still want the sharpest area on the subject and not on the surroundings.Composition in photos: too busy and dsitracting from subjetc in my opinion.Secrets? There are no secrets revealed in this book unless it is the very first photography book that gets to your hands for the very first time.
