Here is a book that stands out. Well explained, visually attractive in presenting his subjects, he offers valuable learning course for beginners (very appropriate) and pleasant for experienced (which can take valuable advice). Sheets pages after pages are well explained, clear, objective, and ... that's where it's nice, subjective (with the personal opinion of the author). It reads like bun, and this is not just another book on the photo.
If you want to begin to increase in photo, then seriously, starting with this one! I'm doing photography for 30 years, I teach, and I dip into this book ultra relevant ideas.
