00:00Hidden deep in southwest China, this sacred site offers a window into the past.
00:09The rock carvings of Tazou are a stunning example of Chinese cave art,
00:14but perhaps the most important thing about these statues here
00:17is what they tell us about the life and belief in China more than a thousand years ago.
00:21I'll discover how advanced digital technology and AI are safeguarding these relics.
00:30In Europe, we'll also see what's being done to restore a Dutch national treasure.
00:35Welcome to Crossing Cultures. Join us as we explore the very best traditions of both China and Europe.
00:53The Tazou rock carvings are one of the finest examples of Chinese cave temple art.
01:00Dating from the 9th to the 13th centuries, more than 10,000 figures chart the evolution of religious belief and artistic expression.
01:10In Yuanjue cave, twelve bodhisattvas advance towards perfect enlightenment.
01:15They are safeguarded by an ingenious stone drainage system that has protected the grotto for centuries.
01:22I heard that in Yuanjue cave is an important project of research.
01:27This project is designed to build a human body of human beings and artificial intelligence system.
01:33This project is designed to build a human body and artificial intelligence system.
01:34The 3-way病害標柱 is not only a 3-way可视化,
01:39but it is also from the平面 to the立体 of a human technology.
01:43Do you have any difficulties in the field of the field?
01:48You can see that the building of the field of the field has a lot of protective and protective structures.
01:53The protective structures are used to make a shield and a square.
02:00This is a huge challenge for our data collection.
02:04It's a big challenge.
02:34When you look at the recovery method,
02:37you can use AI and a large model
02:41to make a more convenient image of this method.
02:49Such technological advances allow researchers
02:52to capture and study the site with precision,
02:54while also making the carvings accessible
02:57to a worldwide audience.
03:01From the ancient rock art here in Chongqing,
03:03let's head to Europe to discover the latest effort
03:06to restore a Dutch masterpiece, Paul has more.
03:16Bikes, bridges, cafes, canals.
03:19Amsterdam conjures up so many things.
03:23But if there's one place that truly captures
03:25its cultural heart, it's here, the Rijksmuseum.
03:29A temple to the Dutch Golden Age,
03:31and one painting still reigns supreme,
03:34Rembrandt's Night Watch.
03:36The Night Watch is Rembrandt's most ambitious painting.
03:40He painted it at the pinnacle of his career,
03:43and it's special because it's also a deeply humane painting.
03:48Since 2019, a major restoration in full view of the public
03:52has been taking place.
03:53Right now, conservators like Esther are delicately removing
03:57the old varnish from the imposing canvas.
04:02Esther, why are you removing the varnish?
04:04We are removing the varnish from the Night Watch
04:06because it's a very yellow layer.
04:08It has aged over time.
04:10It's 50 years old.
04:11And it's also a bit greyish because it doesn't saturate
04:15the paint layers as well as it should.
04:17And how complex is a restoration like this?
04:20What are the main challenges you face?
04:22The painting is very big, which is a challenge in and of itself.
04:25The project itself is very big.
04:27We're doing a lot of research,
04:28and that makes everything exponentially bigger and more complex.
04:34Every move Esther makes is supported by the museum's science team,
04:38who examine the masterpiece in microscopic detail.
04:46The research we do with our team is really to understand
04:49the composition and condition of the night watch,
04:52and this information helps conservators' stories
04:55to make decisions in their treatment.
04:58So we have technology where we really scan through the painting,
05:01we do imaging, but we also take tiny samples
05:04to really dive into the paint to really understand
05:06what has happened over these 400 years.
05:12The night watch is really an icon for the Netherlands,
05:16and this restoration we're doing for the future,
05:19and future generations will see a night watch
05:22which will be much clearer, easier to read, but also have more depth.
05:27The contrast between light and dark, for which Rembrandt is so famous,
05:31will be more apparent.
05:32So that's why we decided that this is the time to restore it.
05:36400 years have taken their toll.
05:39Previous restorations, exposure to the elements,
05:42and a violent attack of all left scars.
05:45So what's the painting's condition today?
05:49The condition of the painting is, I would love to say, good,
05:52but if you're looking under the microscope,
05:54you can see that it's a damaged paint surface, which is not strange.
05:58I mean, it is 400 years old, but, yeah, it's compromised.
06:03As for restoring one of the world's greatest paintings
06:06in front of the public, that was never in doubt.
06:09The night watch, it's, in a sense, world heritage,
06:12and it belongs to everyone.
06:14And we felt that the public has the right
06:16to see what we're doing to the painting.
06:20The Rijksmuseum has also moved much of its vast collection online,
06:25another innovative way in which it engages its audience.
06:30The public changes, and you have to keep changing
06:33and finding new ways of presentation.
06:37So I think it's incredibly important for a museum
06:40to keep on moving, to keep on changing,
06:44and to keep on showing this fantastic art, which is timeless.
06:56To bring Dazu's ancient heritage to life,
06:58an 8K panoramic dome now allows visitors
07:02to study the carvings in stunning detail.
07:04The Rijksmuseum is called the world,
07:07the largest mystery in the world of the centuries,
07:08the world of the centuries.
07:09It represents the highest level of an 18-19 century
07:12where the world of the centuries
07:13is the greatest mystery in the centuries.
07:15It is using the digitizedRED technology
07:18to show the art of the centuries
07:19or above the centuries,
07:20and it has been organized,
07:22and it is designed to look good at the part
07:24of the whole of the 15th century.
07:26And it also shows a role in 19-20 years
07:28that has also earned the service
07:29of the representation in the 19th century as well.
07:32from the past to the present the latest technology aims to ensure stories once etched in stone
07:41continue to resonate so there you have it some innovative and inspiring ways in which
07:48china and europe are working to display and preserve a heritage for now that's all from
07:53me here in chongqing until the next time thanks for watching
