Since I teach perspective as part of the Drawing course I am always interested in finding new ways to explain the subject. The book - Sketching Perspective - by Ilga Leimanis starts in a way I found inviting. Her examples seem free and spontaneous. Her perspective examples seem approachable rather than technically intimidating as some complex technical perspective drawings. There is a chapter called Reconstructing Space from Memory or Imagination - interesting. It's a topic I’ve never seen addressed in a book about perspective. I thought it was a good book and covered the subject well.
Ilga is an urban sketcher, so perspective is central to her craft. She also, as is common with the genre, works quickly and loosely, so you won’t find architectural or measured drawings here, and hooray for that. What mainly sets this apart from other books on perspective is the way Ilga uses the technique in very fluid drawings that capture character as much as appearance. Only you can decide whether this works for you but, if it does, it should be rather successful.
Through a series of well-explained sections, Ilga shows you how to look at the subject before you and to break each area down so that you understand completely how to tackle perspective with speed and confidence in a range of materials.
