This document discusses different types of pictures including closed form, open form, scale, linear perspective, atmospheric perspective, lighting, and texture. Closed form shows the entire picture, while open form does not. Scale is demonstrated through trees lining up and fading in size. Linear perspective uses horizontal lines converging at a single point. Atmospheric perspective uses warm colors in front and cool in back. Lighting shows light increasing and shadows fading. Texture is shown through how light hits a textured surface like a wall.
