The human eye does not have obvious advantages in visual perception, and compared with other visually developed animals, our visual ability is limited by thinking and cognition, which can easily lead to wrong judgments. This is fully reflected in the visual works that Xiao Jiang has introduced to everyone. Some artists are adept at exploiting the imperfections of the human eye to create unique works, and this art form is known as trompe l'oeil art. British artist Lee Wagstaff is one of them. 
Lee Wagstaff was born in 1969 and is known for his drawings. However, in 2007 he began experimenting with trompe l'oeil portraits, which took his artistic career to new heights. These faces, which are used to make hallucinatory portraits, are very special because all the faces in the paintings are automatically generated by the computer, and there are no prototypes found in the real world. The first step in creating an illusion portrait is to use a computer to automatically create a portrait of an object. Next, the artist adds hidden patterns to the portrait work, which include geometric shapes such as circles, diamonds, and squares. Standing at the right distance, the viewer can see the hidden portrait of the person. When viewing these works on a mobile phone screen, people with good eyesight can only see geometric patterns, while some nearsighted friends can clearly see the entire portrait. 
In order to make the portrait more realistic, Lee Wagstaff also processed the portrait. He deliberately magnifies key areas such as the eyes, nose, and lips and uses shadows to further accentuate them. These portraits, hidden beneath the pattern, become more difficult to see the more closely you look for them, but instead the portrait becomes clear when the viewer squints. Not only do the eyes help us record and analyze patterns, but over time we gradually improve our ability to identify hidden portraits. The first time you ** these works, it takes some time to discover the hidden portraits; But wait until the second time, and the portrait will automatically appear. These trompe l'oeil portraits are so mysterious and playful that you can't help but want to spend time looking for hidden portraits. Lee Wagstaff's art not only challenges our visual perceptions, but also stimulates our curiosity and desire to explore. By appreciating these works, we can feel the unique charm and infinite possibilities of trompe l'oeil art.
