(David Hockney) how does Hockney create his photo collages? what did he did? and what is he trying to achieve?

He creates his photo collages by taking polaroids of different sections of what he sees. He then puts them all together to express how the passing of time, facial expressions, and emotions can change in a matter of seconds. He is trying to achieve people's understanding of how all of these captures of moments change the perspective of space.

Explanation: David Hockney is a painter and photographer that creates photo collages by capturing what he sees into hundreds of polaroids which form the complete landscape altogether. His goal is to transmit how space is just an illusion and how time, facial expressions, and emotions can change and be captured into a single representation.
