Modern mobile photography has stepped far forward, turning from a simple way of capturing moments into a full-fledged creative tool. One of the most popular effects, which was previously available only to owners of expensive SLR cameras, is the bokeh effect. This technique allows you to visually separate the subject from the background, drawing the viewer's attention to the main thing and giving the photo a professional look. background blur or bokeh effect. This technique allows you to visually separate your subject from the background, drawing the viewer's attention to the main thing and giving the photo a professional look.
Owners of smartphones with base Android have at their disposal many ways to achieve this result. This could be a built-in camera feature, a third-party app, or even an online service that runs right in the browser. The choice of a specific method directly depends on the model of your device, version of the operating system and the required quality of processing.
In this guide we will examine in detail the various algorithms and tools that will help you create a bokeh effect on any Android device. We will look at both the native capabilities of the system and third-party software that uses artificial intelligence to accurately determine the boundaries of objects.
Use the built-in camera capabilities
Most modern mid-range and flagship smartphones are equipped with software algorithms to simulate shallow depth of field. This mode is usually called "Portrait" or "Live Focus". The principle of operation is based on using data from a telephoto lens or focusing system to build a depth map.
To activate this feature, open the camera application and find the appropriate mode. Often settings allow you to adjust the degree of blur before shooting. On some models Samsung or Xiaomi the aperture slider appears directly in the viewfinder.
⚠️ Attention: The effectiveness of the built-in mode directly depends on the lighting. In low light, algorithms may mistakenly blur the edges of hair or clothing, creating artifacts.
For best results, maintain a distance of about 1-2 meters from the subject. The camera must focus clearly on the face or subject before you take the photo. If your device supports shooting in RAW with depth data, you will be able to change the strength of the blur after taking the photo.
Use a tripod or rest your phone on a stationary object when shooting in Portrait mode to avoid blurring of the contours due to hand shake.
Third-party apps for blurring the background
If the standard camera of your smartphone cannot blur the background or does it not well enough, specialized applications from Google Playwill come to the rescue. They use powerful neural network algorithms to analyze images and highlight objects, often performing better than built-in solutions.
The leaders in this category are Adobe Lightroom, Snapseed i AfterFocus. These apps offer a variety of tools, from automatic depth detection to a manual brush for fine-tuning areas of blur. Some of them even allow you to change the shape of the bokeh, simulating different lenses.
Let's consider the main features of popular editors:
- 📸 Adobe Lightroom —offers professional masking tools and selective application of blur effects.
- 🎨 Snapseed —contains the “Spot” tool, which allows you to selectively blur the background, although it requires manual work.
- 🤖 AfterFocus —specializes specifically in creating a bokeh effect with smart foreground selection.
- ✨ PicsArt —a combine for editing, where the blur effect can be applied as a filter or use the “Blur” tool.
Using third-party software gives you more control over the final image. You can not only adjust the intensity, but also apply a gradient blur, which looks more natural to the human eye.
Step-by-step guide: processing in Snapseed
App Snapseed from Google is one of the most popular free editing tools. It does not have a fully automatic portrait mode, but allows you to achieve excellent results manually or semi-automatically.
To begin, upload a photo to the application. Go to the tools menu and select "Spot". Here you will need to use your finger to indicate the area that needs to be sharp, or, conversely, the one that needs to be blurred, depending on the selected mask mode.
☑️ Algorithm of actions in Snapseed
After applying the mask, proceed to setting the parameters. You can adjust the strength of the effect and switch between zones. It is important to work carefully, zooming in so as not to affect the outline of the object.
⚠️ Note: The Snapseed Spot tool does not save the mask as a separate layer. If you make a mistake, you'll have to start processing again, so save the source.
Once you've finished editing, export the image in high quality. Format JPG with 100% quality will ensure minimal loss of detail.
Online services and artificial intelligence
In the era of cloud computing, it is not necessary to install heavy applications. There are many web services that process photos remotely using powerful server servers. This is an ideal option for weak smartphones that slow down when processing graphics. neural networks. This is an ideal option for weak smartphones that slow down when processing graphics.
Sites like Remove.bg or Fotor automatically detect an object and blur the background in a matter of seconds. Artificial intelligence algorithms analyze millions of images to accurately separate a person or object from the environment, even if the background is complex.
Advantages of online processing:
- 🌐 Does not require installation of additional software on the device.
- ⚡ Instant results thanks to powerful servers.
- 🧠 High accuracy in identifying complex objects (hair, transparent objects).
However, it is worth remembering about confidentiality. By uploading a photo to the network, you transfer data to third parties. For personal family archives, it is better to use offline applications.
Why do online services work faster?
The servers on which neural networks run are equipped with powerful video cards that process images in parallel, while the mobile processor does it sequentially and more slowly.
Comparison of photo processing methods
To make it easier for you to choose the appropriate method, we have prepared a comparison table. It will help you evaluate the pros and cons of each method depending on your goals and device capabilities.
| Method | Result quality | Complexity | Internet required |
|---|---|---|---|
| Portrait mode | High (depends on the camera) | Low | No |
| Applications (Snapseed) | Average/High | Average | No |
| Online services (AI) | Very high | Low | Yes |
| Prof. editors (Lightroom) | Maximum | High | No |
The choice of tool depends on the task. For quick publication on social networks, an online service or a built-in camera is suitable. For artistic processing and printing, it is better to use professional applications with manual settings.
For daily use, the optimal balance of quality and speed is the “Portrait” mode in the camera, complemented by easy correction in the editor.
Tips for an ideal result
Regardless of the chosen method, there are universal rules that will help improve the final image. First, try to keep some distance between the subject and the background. If a person is standing close to the wall, the app will not be able to correctly separate the plans.
Secondly, watch the contrast. The object must be different in color or brightness from the background. Shooting a person in black clothing against a black background will create problems for any selection algorithm.
Use good lighting. Natural light preferably flash, which often creates hard shadows and highlights that interfere with software filters.
⚠️ Attention: Application interfaces and camera algorithms are constantly updated. The location of the buttons or the name of the functions may differ depending on the version Android and the manufacturer's shell.
Experiment with different applications to find the one that gives the most natural picture on your device. Sometimes a combination of two tools gives a better result than using one.
What to do if the edges of an object are “eaten”?
Try reducing the strength of the blur or use retouching tools to manually paint over artifacts with the color of the background or object.
Frequently asked questions
Is it possible to blur the background of a ready-made photo?
Yes, this is possible using applications like Snapseed, PicsArt or online services. The quality will depend on the complexity of the background and the contrast of the subject.
Why is there no “Portrait” mode on my phone?
This mode requires certain hardware capabilities or a second camera. On older or budget models it may not be present, but it can be replaced with third-party software.
Does blur affect the quality of the photo itself?
If processed correctly, the quality of the main object does not suffer. However, strong compression when saving or aggressive filters can reduce the overall detail of the image.
Do you need the Internet to run applications?
Most applications work offline, using the phone's processor. Online services require a network connection to process the image on a remote server.
