The Art of Perspective - book review
How do you get perspective on your art? Step back from it, go vist galleries to see other work, stand on your head and squint one eye?
If anyone can do that last one, I’d love to see it - it would make a great marketing photo. I can just imagine an artist in a painting smock, standing on their head, with a brush stuck out the side of their mouth, squinting at an abstract piece of art on an easel…. 
Anyway this book won’t tell you how to gain perspective about your work, but it will tell you how to put perspective IN it. The aim of perspective is to create the illusion of three dimensions in a two dimensional surface, or basically to make it look real.
The Art of Perspective by Phil Metzgar is, as it claims, the ultimate guide for artists in every medium. It was well written - I could sit down and just read it instead of trying to drag the main points from it while my eyelids were getting heavier and heavier. (I have gotten “art” books before that would have been better prescriptions for insomniacs.) I learned quite a bit that I’ll be able to apply to my relief sculpting.
The book has two main sections. The first, on natural perspective, covers the more intuitive parts of making something look dimensional, such as making objects in the distance lighter and bluer, and not having the same amount of detail in both the foreground and background since our eyes will only focus sharply on one area. It was very interesting. There were alot of “Duh, why didn’t I think of that?” or “Hmm, that makes sense,” moments while reading, but the nice part of it all was that it DID make sense and I think I’ll be able to apply the concepts.
The section on linear perspective was a bit more involved, but would be very useful if you ever want to do buildings, roads, etc. It covers horizon lines and drawing by the rules. Even if you never draw out all your marking lines, it helps to know the concepts so you can apply them intuitively.
