The technique of showing an item or human body in a picture so as to create the illusion of projection or extension in space is known as foreshortening.
It’s a technique for rendering a specific object or figure in a photograph in great detail.
In perspective, foreshortening is a method that creates the sense of an item retreating dramatically into the distant or background. The illusion is generated by the object being shorter than it actually is, giving it the appearance of being compressed. It’s a great method to give paintings and drawings more depth and dimension.
Everything drawn in perspective is subject to foreshortening. Buildings, landscapes, still life objects, and figures are all examples of this.
