As AI continues to evolve and affect life in myriad ways, we speak to Hong Kong artists who use machine learning to create art that retraces what it means to be human

Hong Kong digital artist Victor Wong Wang-tat, who practises traditional ink art as a hobby, was proud to show his work to his fellow practitioners at one of Hong Kong Ink Painting Society’s gatherings. A sturdy mountain, made up of steady, and powerful brushstrokes, sits in the centre of the rice paper; the changing black and grey gradation of the ink lines standing in stark contrast to the blank white space to create an ethereal landscape as if clouds are floating above the valleys. Wong recalls the Ink Painting Society chairman’s immediate puzzlement: “This painting shows the level of experience and skill that a senior painter has, but strangely the artist seems to paint far more steadily than most of us older artists are capable of now.”

The older man was astounded to learn that the painting had been created by AI Gemini, Hong Kong’s first AI robotic arm to specialise in ink art, designed by Wong. This revelation led fellow Ink Painting Society members to question which ink art masters’ works Wong had fed to AI Gemini’s machine learning system, and whether the resulting piece should be considered art.

Wong isn’t the only artist facing questions from AI sceptics. Since the considerable rise in the adoption of AI around the world in the last five years, apps such as Tensorflow and Stable Diffusion—open-source AI platforms that collect artworks and images that exist online to create a database from which new works can be generated— have accumulated a solid fanbase who want to create sophisticated works in the style of famous artists with a few prompts and one click of a button. But such creations can lead to infringement—art can be uploaded without the artist’s permission or knowledge—an inundation of disinformation, and the possibility that artists will be left jobless.

At the time of writing, Hong Kong hadn’t seen any lawsuits concerning AI-generated art, according to Weiken Yau, a partner at law firm Haldanes who regularly advises on publishing and digital licensing agreements. That doesn’t mean cases won’t come about. The updated Copyright Ordinance, which Yau says would likely be the ordinance for monitoring AI art in Hong Kong, took effect on May 1 this year to “strengthen copyright protection in the digital environment”, according to the government’s news website. While there are still grey areas in the interpretation of AI art, its ownership and the liability of involved parties, Yau says it all comes down to “comparing whether the AI work created is strikingly similar to works owned by others. No exemption or allowance is granted to the users using the AI tools.” He thinks that ultimately, AI app users will bear the primary responsibility for ensuring that art generated by AI isn’t a material reproduction of artwork owned by someone else. “Otherwise, my advice would probably be that the person should seek to get a licence from the rightful owner, or [ensure] they qualify under any of the statutory exemptions that are already in place.” These include satire, parody, caricature and pastiche, commenting on current events, quotation, education and other purposes that fall within the fair dealing exception.

Wong and his robotic arm may be able dodge the copyright infringement issue as his purpose isn’t to generate images by imitating existing artworks or ink art masters. “In the history of any art, apprentices go to galleries to copy the style of a master to learn their techniques, so imitating a style isn’t something new,” he says. “I don’t want my AI to reproduce ink art paintings based on existing styles but to learn how to produce ink art. I want to blend AI with ink art as a modern means to present and preserve ink artists’ spirit and creative process.”

He learnt that ink artists travel to mountainous areas to observe the landscape, then paint it from memory. Named after Wong’s zodiac sign, AI Gemini was designed to imitate this creative process. This is how it works: Wong wrote a unique algorithm for AI Gemini for image generation. He physically moved the robot arm to make it take ink from the inkwell, and draw lines of different weights and brushstrokes. All those motions were translated into data understood by AI Gemini. Instead of keywords, AI Gemini uses timestamps—date, time and year—and weather conditions— temperature, humidity and rainfall—taken at the moment of creation as the parameters to represent the geographical conditions for generating an imagined 3D mountain image, which Wong calls the “mindscape”, to be stored in AI Gemini’s central system. This process is similar to a human artist looking at a view and imprinting the sight of the mountain into the mind. For example, if AI Gemini is creating a piece on a rainy day, the numerical value of the volume of rain entered into Wong’s algorithm will instruct AI Gemini to adjust the amount of water to dilute the ink for a washed-out effect on the mountain.

Based on what AI Gemini learns as to what constitutes aesthetic proportions in ink art paintings, AI Gemini’s program selects a part of the imaginary mountain, uniquely created each time, to be laid down in the actual artwork. The robot arm then gets to work; it applies different amounts of force, painting methods and proportions of water to create a painting with varying colour gradations, shadows effects, depth and textures Each of the paintings is unique and no existing paintings are copied. “The best way to ensure that AI doesn’t mimic Xu Bei Hong, Lui Shou Kwan or Zhang Da Qian is to not feed it with any existing ink artworks at all,” Wong says.

Wong, who has an engineering background, sees a similarity between humans and AI. “If you look at emotions from a scientific perspective, they are your body’s reactions to external stimuli created by hormonal changes. For example, if I paint on a rainy day after getting stuck in traffic, my frustration will impact the way I paint,” he explains. Wong sees AI as one way of emulating emotions, as AI Gemini also “creates” differently based on changing external conditions. “I don’t dismiss painting ink art in the traditional way, but I believe AI is a new possible way to do it—and may be the way to pass on this Chinese tradition in the future,” he says.

While local new media artist Henry Chu, the creative director of design studio Pill & Pillow, may not share Wong’s pioneering view of AI, his work also focuses on exploring ways of using AI in his artistic practice instead of seeing it as a tool to generate another digital image. Last year, Chu was invited by Bank of China (BOC) to collaborate with former Miss Hong Kong Grace Chan to create three AI artworks—Quadtree of Dawn, Quadtree of Summer and Quadtree of South—that represent the bank’s vision for the city’s future.

Chan first explored and keyed in different prompts based on the bank’s themes, which allowed the program to produce a first draft, which Chu then adjusted manually to refine details which AI hadn’t perfected; Chu estimates that AI created 90 per cent of the visuals. The remaining 10 per cent consisted of manual adjustments as well designing a frame for each piece of AI-generated artwork with similar colours or images that fit their respective themes.

A “creative technologist” who uses programming to design websites and digital advertising for his clients, Chu sees the benefit of AI in visual design. He observes that the design and advertising industries in Hong Kong have been using AI for years, as it is a useful tool that saves time in visualising design concepts, which can then be modified accordingly to create real products such as furniture. “Midjourney and Stable Diffusion aren’t new, but they used to be only accessible by a small group of people,” he says. “Then six months ago, much like the sudden hype for cryptocurrency and NFTs in 2017, AI became available to a wider population of people. Those who hadn’t had access thought it was magic.”

He thinks the BOC project is “a very good demonstration of how AI is going to be in the near future: it can handle the things that you don’t want to do while you focus on the things that you enjoy spending time on.” For instance, AI helped visualise the more abstract ideas which Chu otherwise would have had to hire an artist to sketch, which would have been more expensive and taken longer.

Still, Chu is aware of how quickly AI can learn. He points to the well-known, well-mocked example of human hands. In February, AI programs produced hands with bulbous palms, too many fingers and overly elongated wrists; within a month, Midjourney had released software capable of churning out flawless hands. “I always try to be creative with how I incorporate AI in my art,” he says. “The technology itself is not important; it’s how I use the technology that is.”

Chris Cheung Hon-him, creative director of Hong Kong art tech studio Xcept, adds, “While an AI user now may be able to realise a visual just as an artist can, what differentiates the two is how the artist is supposed to have deeper thoughts in the creative process, and messages to convey through the work.”

Cheung’s team explored AI’s questionable nature in an art installation in May at Freespace, West Kowloon. Sentient Mirror is an installation of four mirrors, which served as a companion piece to Canto-pop singer Ivana Wong’s Pink Canvas Exhibition Concert, which examined Hong Kong’s labelling culture. The mirrors—which generated images themed around sci-fi, western classical heroes, mythic heroes from Asian cultures and food— were linked to a computer keyboard on which visitors could type words they had been labelled with or heard of as labels. When visitors walked up to the mirrors, the app would generate an image by analysing their appearance and matching them with prompts, which could have been keyed in by any visitors and were stored into the system to be applied to anyone who approached the mirrors. Some of the images that appeared included a cyborg accompanied by words like “wine loving”; a princess clutching handbags to show the visitor was “materialistic”; and someone dramatically being turned into a personified pizza which reflected them as food-loving.

Cheung observes that “so far in Hong Kong, people use AI for fun and don’t see the results as artwork. It’s not new for artists in Hong Kong to use AI to visualise their concepts in the creative process. But some of them don’t claim that AI-generated content as their own work.” He is worried, however, that AI may discourage creativity. “While AI relies on existing human creations now, we don’t know if it will have the ability to think and create on its own in the future,” he says. “My concern is that if artists aren’t aware that they can be replaced by AI [and only use it to generate works without thought], they will not produce original ideas anymore. The important thing is to reflect on what position we take as humans and how we should learn and evolve as AI evolves.

But it’s not all doom and gloom. “When photography was invented in 1826, painters thought the camera would replace the recording function of paintings. But did that stop them from lifting a brush?” asks Wong. “As a digital artist, I still paint ink art as a hobby. It helps me express my emotions. Paintings have an aesthetic and craftsmanship value that AI art can never replace.”
