Any perspective exercises I can do?

[Colaffee]

I'm taking a life drawing class, and doing the 30 sec pose exercise on Posemaniacs at least 10 minutes a day, but I realized my perspective could use some work. So are there any exercises I could do to practice my perspective?

Perspective is technical, not intuitive or subjective.

You just have to learn the rules.

Pick up a book in the library or buy one at the bookstore.

I've been going through Vanishing Point, which if I recall was pretty cheap on Amazon. It explains all the rules and has exercises at the end of the chapters that you can follow along in kind of a step by step process as you learn the rules. I think it's helped me quite a bit so far, though I really do need to use the rules more often.

Perpsective! For Comic Book Artists by David Chelsea is pretty solid. The book is basically a series of lessons provided to a character within the narrative, so if you follow along at the same time you'll perform various exercises intended to pass on the basics.

As Symson says, perspective is a technical subject, with defined rules and applications. It's basically applied mathematics.
