Photography is an art that, thanks to technology, has become an integral part of our daily lives. With a smartphone in your pocket, anyone can seize the moment and turn it into an indelible memory. Among the many features that have revolutionized mobile photography, Portrait Mode stands out for its ability to create professional-looking images. This function, leveraging artificial intelligence, allows you to achieve the so-called bokeh effect, a technique that artistically blurs the background to make the foreground subject stand out. Born to simulate the depth of field of DSLR cameras, today Portrait Mode is a powerful and accessible tool for everyone, combining technological innovation with a long artistic tradition.
In Italy and Mediterranean culture, the portrait has always played a central role, a way to celebrate the individual and tell their story. From imperial portraits on Roman coins to Renaissance masterpieces, the need to immortalize a face is deeply rooted. Today, this tradition continues through the screens of our smartphones, where Portrait Mode becomes the digital brush with which we paint our moments. This article will explore simply and clearly how this technology works, how to make the most of it to get memorable shots, and how it fits into the European cultural context, where mobile photography is now a universal language.
What is the bokeh effect and how does it work on smartphones
The term bokeh comes from the Japanese “boke” (ボケ), which means “blur” or “mental haze”. In photography, it describes the aesthetic quality of the out-of-focus areas of an image, intentionally created to give depth and draw attention to the main subject. In professional cameras, this effect is achieved using lenses with a wide aperture (a low f/ number), which reduces the depth of field. Consequently, the background appears soft and indistinct, with points of light transforming into pleasing luminous circles. This not only eliminates distracting elements but also gives the photo an evocative and three-dimensional atmosphere.
Smartphones, due to their small sensors and lenses, cannot create natural bokeh in the same way. To overcome this hardware limitation, they use a combination of software and, in more advanced models, multiple cameras. This approach is known as computational photography. Phones with multiple lenses use one lens to capture the main image and another (usually a telephoto lens) to measure the distance of objects in the scene, creating a “depth map”. Artificial intelligence analyzes this data, recognizes the foreground subject, and applies a digital blur to everything else, simulating the bokeh effect.
The technology behind the magic: hardware and software compared
The magic of Portrait Mode stems from the close collaboration between hardware and software. Initially, the effect was entrusted almost exclusively to complex software algorithms. Today, the best smartphones on the market combine advanced physical components with increasingly sophisticated artificial intelligence. Models equipped with dual or triple camera systems use different lenses to perceive depth in a way similar to the human eye. A main sensor captures the image, while a second sensor, often a telephoto lens or a ToF (Time-of-Flight) sensor, calculates the distance between the camera and the various elements of the scene.
The software steps in to process this information. Machine learning algorithms are trained to recognize faces, people, and objects, separating them precisely from the background. Once the subject is isolated, the image processor applies a gradual and realistic blur to the background, often allowing the user to adjust its intensity even after shooting. The real challenge, and where the difference between various models is noticeable, lies in handling complex details like hair, glasses, or irregular edges. While early attempts produced a “fake” effect, similar to a sticker pasted on a blurred background, modern systems offer a much more natural and convincing result. For those who wish to further improve their shots, there are also numerous photo editing apps that offer advanced tools to perfect the bokeh effect.
Practical Guide to Portrait Mode
Getting professional-quality portraits with your smartphone is simpler than you might think. By following a few practical tips, you can transform an ordinary shot into an extraordinary image. The key is understanding and controlling the few fundamental elements that determine the success of a photo in Portrait Mode.
Managing light: the secret to a perfect portrait
Light is the most important element in photography. Portrait Mode works best in good lighting conditions, as it helps the artificial intelligence precisely distinguish the subject from the background. Direct, harsh light, like the midday sun, creates sharp and unflattering shadows on the face. It is preferable to look for diffused and soft light, such as that found in the shade of a tree, near a window, or during the “golden hours”, i.e., just after sunrise and before sunset. A cloudy sky can act as a natural diffuser, ensuring uniform and ideal lighting. Experimenting with the subject’s position relative to the light source can create interesting effects, such as a halo of light on the hair that helps further separate the figure from the background. If lighting conditions are poor, it is useful to know the tricks for taking night photos with your smartphone.
Composition and subject: highlighting the protagonist
A good composition guides the observer’s eye and makes the image more balanced and interesting. A fundamental technique is the rule of thirds, which involves positioning the subject along the imaginary lines that divide the frame into nine sections, rather than in the center. Many smartphones allow you to display a grid to facilitate this operation. The distance between the camera, subject, and background is crucial: for a pronounced bokeh effect, the subject should be at a distance between one and two meters from the camera, while the background should be as far away as possible. When taking a close-up, the focus must be on the subject’s eyes, particularly the one closest to the lens. Even though it is called “Portrait Mode”, this function is also perfect for photographing objects, animals, or flowers, provided there is sufficient contrast to separate them from the background.

Common mistakes to avoid
To get the most out of Portrait Mode, it is important to avoid some common mistakes. One of the main ones is using digital zoom, which degrades image quality; it is always better to physically move closer to the subject. Another mistake is shooting in very low light conditions, where the camera struggles to separate the planes and can produce a noisy image or inaccurate blurring. Also, a background that is too complex or close to the subject can confuse the algorithm, leading to an unnatural bokeh effect with poorly “cut” edges. Finally, it is advisable not to overdo post-shot editing and filters. Although many apps offer options to adjust brightness and contrast, excessive retouching can make the photo look artificial. Naturalness is often synonymous with professionalism.
The portrait in Italian culture: from tradition to digital innovation
The portrait genre has deep roots in Italian and Mediterranean culture, constantly evolving to reflect social and technological changes. Since Roman antiquity, the effigy was a powerful tool for individual affirmation and power, used to pass down the image of emperors and public figures. The Renaissance marked a fundamental turning point, placing man at the center of the universe and transforming the portrait into an autonomous artistic genre, capable of exploring not only the physiognomy but also the psychology of the subject. Artists like Raphael and Piero della Francesca created masterpieces that still communicate the charisma and social status of their patrons today.
This long tradition of individual representation finds a new expression today in digital photography. The advent of smartphones has democratized the art of the portrait, making it accessible to millions of people. Portrait Mode, in particular, represents a bridge between the past and the future: it combines the ancient need to immortalize a face with the most modern artificial intelligence technologies. In the European market, where image sharing on social media is a mass cultural phenomenon, this function allows anyone to create and share their own visual narrative. The smartphone thus becomes a digital canvas, a tool that continues, in new forms, a centuries-old tradition deeply rooted in our culture.
- Choose the ideal lighting
Avoid harsh midday light. Prefer soft and diffused light, like that of the ‘golden hours’ or in the shade, to help the AI clearly separate the subject from the background.
- Manage distances
Position yourself at a distance between 1 and 2 meters from the subject. Ensure the background is sufficiently far away to maximize the bokeh effect and give depth to the shot.
- Watch the composition
Activate the camera grid and apply the rule of thirds. Position the subject along the lateral guidelines rather than perfectly in the center for a more dynamic image.
- Focus on the gaze
Tap the screen to lock focus on the subject’s eyes, particularly the one closest to you. A sharp gaze is the focal point that brings the portrait to life.
- Simplify the background
Avoid overly complex or chaotic backgrounds that could confuse the blurring algorithm. A clean background ensures more precise edges, especially around hair.
- Get closer without zooming
Do not use digital zoom to tighten the frame, as it degrades quality. Physically move closer to the subject to keep details sharp and the effect natural.
Conclusions
Portrait Mode has transformed smartphone photography, democratizing a technique once reserved for professional photographers. Combining advanced hardware and intelligent software, this function allows for the creation of visually striking portraits, highlighting the subject through the elegant blurring of the background, or bokeh effect. As we have seen, achieving excellent results requires more than just relying on technology: it is fundamental to understand the basic principles of photography, such as light management and composition rules. Soft, diffused light and an adequate distance between subject and background are key elements to help artificial intelligence work at its best.
In an Italian and European cultural context, where personal image and its sharing have increasing social value, Portrait Mode asserts itself as a powerful and immediate tool of expression. It represents the natural evolution of a centuries-old artistic tradition, that of the portrait, which continues to celebrate the individual by adapting to new digital languages. Mastering this function means not only taking better photos but also acquiring greater creative awareness, transforming the device we hold in our pockets into a true storytelling tool.
Frequently Asked Questions
Portrait Mode is a feature of modern smartphone cameras that focuses on the foreground subject and artistically blurs the background. This effect, known as *bokeh*, simulates the depth of field of a professional camera. Smartphones achieve this result by combining hardware (often two or more lenses) and software based on artificial intelligence. The software creates a «depth map» to distinguish the subject from the background, then applies the blur selectively.
Yes, absolutely. Although the name suggests use for people, Portrait Mode is also effective for non-human subjects like pets, flowers, or food. The important thing is that there is sufficient distance and contrast between the subject and the background to allow the software to identify them correctly. Some older smartphone models might have limitations, working only with human faces, but newer devices and third-party apps have overcome this limit.
An imperfect result can depend on various factors. The most common cause is poor distance between the subject and the background: the further away the background is, the more marked and precise the effect will be. Weak light can also make it difficult for the camera to distinguish the subject’s outlines, leading to inaccurate blurring. Other problems can arise with subjects having complex outlines, like windblown hair or glasses. For an optimal result, ensure there is good lighting and a clear physical separation between your subject and what lies behind.
Yes, many smartphones allow you to modify the intensity of the blur even after shooting. By accessing the phone’s built-in photo editor, you can usually find an option to adjust the «Depth Control» or the aperture (indicated by «ƒ»). This allows you to increase or decrease the level of background blur until you achieve the desired effect. In some cases, it is also possible to completely remove the portrait effect if you change your mind.
To improve your portraits, focus on three key elements. First, *light*: look for natural and diffused light, like that near a window or in the shade, to avoid sharp shadows on the face. Second, *distance*: increase the space between the subject and the background to maximize the blurred effect. Third, *focus*: tap the screen on the subject’s face, preferably on the eyes, to ensure it is the sharpest point of the image. Finally, do not be afraid to experiment with different angles and perspectives for a more creative result.
