** has long become an indispensable way to record daily life.
But since 1839, the French physicist Daguerre invented the world's first camera, to now, it has been less than 200 years. Before the invention of the camera, painting was undoubtedly the most commonly used means of recording major events and portraits.
The painter Rembrandt is undoubtedly the most enthusiastic painter to paint portraits of himself - an average of two per year, leaving more than 100 self-portraits of different styles in his lifetime, so he is affectionately regarded as the earliest "**madman" by the art world.
In fact, Rembrandt is not most famous for **, but for his original style of light and shadow portraiture.
Before Rembrandt, almost all paintings were "photographed" – the light was flushed flat on the face, and there was little contrast between light and dark. Rembrandt, on the other hand, innovatively adjusted the direction of light, making the characters in the portrait more like being illuminated by the side light, so that the faces of the people in the painting have a change of light and shade, light and shadow, and the characters become three-dimensional and vivid.
The dull style of ID photos suddenly has a more aesthetic artistic style.
The culmination of this style is the world-famous painting "Night Watch" on a par with Leonardo da Vinci's "Mona Lisa".
"Night Watch" is a "group photo", a group portrait of that era, just like today's group photo, the position, posture, and even the light and shadow of the face are all regular, similar to the current group photo.
Rembrandt, on the other hand, made each character have his own personality by highlighting the images and expressions of individual figures, and using light effects with strong chiaroscuro.
In 2020, the Rijksmuseum in Amsterdam spent £3 million to digitally scan the famous painting to produce a 44.8 billion pixel ultra-high-definition digital version of Night Watch, allowing more people to feel the shock of the painting in front of mobile phones and computer screens.
Rembrandt is good at using light to shape the body, precise triangular three-dimensional light, outlining the facial contours of the characters, so that the rest of the part is hidden in the light and darkness, making the picture rich and dramatic, and giving full play to the charm of light and shadow.
This revolutionary lighting technique, known as the "Rembrandt light", is still widely used in painting, videography and photography, and is regarded by many professionals as the "top beauty technique" for portrait shooting.
For example, the hit "Flowers" some time ago made extensive use of "Rembrandt light", which made the protagonists beautiful to a new height.
Under the half-bright and half-dark lighting, the proprietress Li Li played by Xin Zhilei has more three-dimensional facial features and a more angular face, which is three-dimensional and deep like an oil painting, adding a different style.
In contrast, Xin Zhilei in the commercial, under the flat light, her face is more round and full, although the makeup is still exquisite, but in contrast, the beauty should be judged in the hearts of the audience.
We live in the same world, but the images recorded with cameras and mobile phones are very different, and the biggest factor that causes the difference in imaging effect is the grasp and understanding of light and shadow.
Take mobile phone photography as an example, flagship models that can be compared to camera image quality emerge in endlessly, and what really stands out is that they have excellent tuning for light and shadow grasping. For example, OPPO's newly launched Find X7 Ultra has been evaluated by many digital bloggers for its performance in leading moving images to return to the aesthetics of natural light and shadow: "Rembrandt lives in the camera module." ”
The most striking thing about the Find X7 Ultra is the graphics configuration. The first-of-its-kind dual periscope and quad main cameras form the Hasselblad Master lens group, providing the most powerful and highest-quality multi-camera zoom capability in six optical quality focal lengths. The 3x periscope telephoto with a 65mm portrait focal length and the 6x periscope telephoto with a 135mm close-up focal length bring the picture detail and color reproduction up to camera-level levels.
In addition, OPPO has also teamed up with Hasselblad, which is particularly outstanding in the field of portraits, and has newly upgraded the professional Hasselblad portrait algorithm on the Find X7 Ultra, driven by a new generation of super light and shadow engine, which avoids over-white, over-bright, and over-polishing filter portrait effects, making mobile portraits closer to people's aesthetics, bringing particularly excellent portrait presentation, especially telephoto portraits, which are even more amazing.
Judging from the actual shooting samples, the natural and soft light spot bokeh effect is accurate to the main body of the hair, and the gradual space blur makes the picture details of the telephoto portrait richer, and the light and shadow of the face more three-dimensional, which has the beauty of light and shadow of the visual effect of "Flowers".
In addition, the Find X7 Ultra also brings the industry's first "Hasselblad Portrait", which can intelligently detect the face of a person, wait for it to turn its head, and then automatically take a shot. At the same time, with the support of the original instantaneous dual-frame technology, it can capture two frames, one long and one short, in a very short time, and superimpose and complement each other, producing images with image quality and color comparable to those of professional Hasselblad cameras.
Judging from the actual shooting samples, the moment you turn your head, the picture freezes, capturing the instant blooming smiles, impromptu jumps, and heart-warming scenes, leaving a portrait capture worth remembering. It's the Spring Festival, with OPPO's new Year of the Dragon watermark, it captures the high-end New Year's flavor.
Of course, not all atmospheric blockbusters can be done in one step, if you accidentally get in with passers-by and debris into the mirror when taking pictures, it is inevitable to carry out post-processing.
With the blessing of the 7 billion parameter end-side model, the Find X7 series brings the "OPPO AI elimination function", which provides another possibility for post-retouching. Just a simple circle of passers-by or sundries, you can use the power of AI to eliminate them in one second, and it will also automatically complete the picture according to the environment in the eliminated area, and the effect is not weaker than that of professional retouching software.
For example, the following ** shows that only a simple circle can eliminate the passers-by behind it, and at the same time complete the scenery on the corresponding position. The AI-generated image does not show any trace of the P-map at all.
The super cool experience brought by the large model on the end of the device, in addition to the convenience of elimination, also brings the vividness of AI ultra-clear group photos.
With the blessing of AI, it can generate high-definition details such as facial texture, hair, and eyebrows for everyone in the group photo, intelligently recognize and enhance the clarity of the face in the group photo, so that everyone can become the protagonist of the clear face. Going home during the Spring Festival, friends gathering, relatives reuniting, a proper group photo artifact.
The beauty of light and shadow has always been the purest gift given by nature.
The sunlight is sprinkled, leaving behind the mottled shadows of trees, people, and buildings, all because of the projection of light and the formation of shadows, bringing a variety of visual effects, constantly triggering our thinking and exploration of beauty.
The artificial light and shadow in the artwork is another real and dreamy atmosphere, which can also immerse us in it and immerse us in the scene.
400 years ago, Rembrandt used light and shadow to embellish and beautify characters, and now, relying on the progress of science and technology, we use video equipment to freeze the beauty of light and shadow in an instant.
