This is a list of some of the books that have been the most influential to my design thinking process, I'll keep adding more over time.
Drawing
Dawing is the most fundamental tool we need to understand and master in order to depict our ideas. Knowing how to draw is more than picture-making, it's a method of construction
Rendering / Painting
Painting & rendering will further help us define and depict our ideas to be able to communicate them in the most complete and unambiguous way
Design Thinking
Once we have the skills to depict and communicate visuals, we need to understand what is the effect of our design decisions on people and what those design decisions should be to accomplish a particular goal
Spatial Design
If you are interested in environmental design, it is really important to understand how we perceive and interact with space in 3 dimensions and not just through the camera
Psychology & Cognition
Underneath all of this, as visual designers, we need to understand de fundamentals of how the human brain perceives and interprets information.
