Juxtaposition
According to Wikipedia, Juxtaposition is defined as "the stimulation of creativity in problem solving, design or other creative pursuit by confronting two unrelated objects or concepts, usually on the goal or problem to be solved on the one hand and a randomly selected object or concept on the other. Similar to oxymoron".
Basically, it can be simplified to one word "using 2 objects to show contrast". We can often see juxtaposition in photographs, drawings or paintings to show the huge difference between 2 same object but with contrast personality. For example a very old man facing a young boy with the age gap of 72 years between them to convey the message the flow of time.
Nowadays, many artists use juxtaposition to satirize the politicians or the government policy. It uses a sarcastic way to portray the corrupted policy of the government.
Here is some example of photographs or artworks that used juxtaposition to portray a messgae to the audience.
