Perspective is that thing that tends to make your brain freeze over. It’s either something you can just do, like colour mixing, or a subject so technical it brings you out in a cold sweat, a bit like dreaming you’re doing an A level maths exam with only a set of times-tables for help.
And that’s the trouble, there’s no way round the fact that perspective can only be explained with the use of lines and diagrams and a fundamental understanding of the vanishing point. Yes, it is a form of geometry.
Giovanni doesn’t shirk the task of getting to grips with the technicalities, but at least you know you’re in good hands and I hope that this will be enough to encourage you to persevere. The technical stuff is kept to a minimum and is concisely, but clearly, explained and there are plenty of his sensitive pencil drawings to show you how things work out in practice.
If this is something you’ve been putting off for longer than you care to admit, this might finally be your chance to nail it.
