Perspective is key
Perspective is one of the foundations of art that you should make an effort to study thoroughly. Incorrect perspective in an image – particularly environments designs – will result in your images lacking any sense of realism and authenticity. Let’s take a basic example. The edges of a cube form three sets of parallel lines: one vertical and two horizontal. Each set has its own vanishing point. Based on these three major sets of lines and the rules of convergence, there are three types of perspective. What distinguishes each type is simply your point of view. The subject matter doesn’t change, just your view of it and how the sets of parallel lines appear to converge.
