I have been checking out the Drawing section of our library and have come across some wondrous books. Drawing is such an important part of any art and getting the perspective right is one of the hardest things to achieve. The Drawing section has several books that deal with this subject from the extremely complex to the simpler versions on this difficult subject. There is a book called ‘Perspective & the Projection of Shadows & Reflection (D/16) it was used to prepare art students for that important ART EXAMINATION. Very complex but if you want to know why distant subjects are grey or how atmosphere affects the colours etc. check this book out. There are also a number of other books that deal with a variety of subject matter from buildings (D/54), boats (D/5), cats (D/59), flowers (D/61) and all manner of other things. There are a number of books dealing with each subject matter, some are very detailed while others point you in the right direction. Of course if you are into Life Drawing or Portraiture they have their own sections in the library. I hope you find that special book.
