Why do we often hear an artist lament, “People don’t understand my work because they don’t understand art?” It’s more likely that the artist doesn’t understand people, especially their physiology. It used to be that artists studied science and math in order to communicate more clearly. For decades now we’ve abandoned that approach in pursuit of self expression and manifestos hoping to redefine art. If that’s for you then have at it as there are no rules to art. There are, however, rules to human perception. If you want your work to speak for itself then you will benefit from understanding the grammar of visual literacy.
