This book ranks as one of the most disappointing photography guides I have ever reviewed. The photography advice is minimal, often misleading, and in many cases wrong. The author seems uncomfortable with digital photography, and implies that zoom lenses are inadequate - in fact today's zoom lenses are of very high quality and used by many, if not most, professionals. Hargan advocates the use of TIFF files, rather than JPEGs, and doesn't even mention RAW files, which are by far the best option for in-camera use. He also suggests that polarizing filters should always be used on cloudy days - another incorrect piece of advice. The author refers to modern (and highly accurate) camera metering systems as "complex gizmos" and "nonsense", and advocates spot metering "green grass in full sunshine" - what do you do at sunrise or sunset or on a cloudy day?
The photographs that are included in the book seem to have been added as an afterthought, and simply don't do justice to the magnificent Blue Ridge Parkway. Most of the images are snapshots, taken in harsh, bright sunshine in the middle of the day - the worst possible lighting for expressive landscape photography. Most of the photographs have overexposed highlights, washed out colors, and blocked shadows.
My advice - invest an extra $5 and purchase Nye Simmons' "Best of the Blue Ridge Parkway - The Ultimate Guide to the Parkway's Best Attractions" instead. This excellent book has twice as many pages (185 vs. 96), much more comprehensive photography advice, plus many more - and far better - photographs, taken in beautiful, expressive, lighting conditions.
