Have you ever taken a perfect shot that was ruined by a bright spot from the sun or the reflection of a flashlight? The problem of glare in photos taken with a smartphone camera is familiar to every owner of an Android device. phone optics, despite constant progress, are still inferior to professional SLR cameras in the fight against glare and reflections on glossy surfaces.
Fortunately, modern image processing technologies offer many solutions. You don't have to be a professional retoucher or buy expensive equipment. It is enough to know what tools are hidden in your smartphone and how to use them correctly. In this article, we will look at effective methods for removing unwanted light spots, from simple built-in functions to powerful artificial intelligence algorithms.
We will look at both standard system tools Androidand third-party software that works wonders with damaged frames. You will learn to understand the nature of glare and prevent its occurrence at the shooting stage. Ready to turn your bad photos into masterpieces? Let's get started.
The nature of glare and its impact on the frame
To effectively deal with the problem, you need to understand its source. Glare they occur when an intense light source hits the lens directly or is reflected from a smooth surface. In the case of smartphones, the situation is aggravated by the small size of the sensor and the peculiarities of the lens coating.
Light passing through the lens system can be reflected many times inside the optical unit, creating so-called “bunnies” or rainbow stains. This phenomenon is called flare. It not only obscures the details of the object, but also reduces the overall contrast of the image, making it faded and washed-out.
This problem is especially common when shooting against the sun, store windows or through window glass. Understanding the physics of the process helps you choose the right removal strategy. Sometimes it is easier to prevent an artifact from appearing than to spend hours removing it in the editor.
⚠️ Attention: Do not try to remove a highlight if it has completely “knocked out” the details of the object in white (overexposure). In such areas, information about color and texture is lost irretrievably, and restoration will require additional drawing, rather than simple correction.
Modern algorithms in processors Snapdragon or Exynos try to compensate for this effect programmatically, but they are not omnipotent. Therefore, knowledge of manual correction methods remains a critical skill for a mobile photographer.
Try slightly changing the angle of the phone relative to the light source before shooting - this will often completely eliminate the need for post-processing.
Using the built-in Google Photos editor
The most accessible tool for correcting shooting errors is already installed on most Android smartphones. The application Google Photos has surprisingly powerful functionality, which is often underestimated by users. To get started, open the desired photo and click the "Edit" button.
First of all, you should use the "Correction" tool. Here you will find sliders for exposure and light. Smoothly reducing the Sveta (Highlights) parameter allows you to return the texture to the overexposed areas, where the highlight is usually hidden. This will not remove it completely, but will make it less noticeable.
Next, go to the “Tools” section and select the “Retouching” function. This tool uses simple cloning algorithms. You just need to press your finger on the highlight area. The system will automatically select neighboring pixels and replace the highlighted area with them.
- 📷 Automatic improvement: The "Auto" button often evens out the white balance, disturbed by bright light.
- 🎨 Spot correction: The "Selective" tool allows you to darken a specific highlight area without affecting the rest frame.
- ✨ Eraser magic: New versions have added the "Magic Eraser" function, which is ideal for removing small reflections.
If the glare takes up half the frame, you will have to combine several tools or go to a more specialized one Software.
Professional retouching in the Snapseed app
When standard tools are not enough, Google comes to the rescue. This free app is considered the gold standard of mobile retouching thanks to its suite of professional tools. The main secret of working with glare here is to use the “Spot” function. Snapseed from Google. This free app is considered the gold standard of mobile retouching thanks to its suite of professional tools. The main secret to working with glare here is to use the “Spot” function.
Activate the tool Tools → Spot. Zoom in to the maximum in the area of the defect. Gently press on the center of the highlight. The algorithm analyzes the texture around and fills the area. For large spots, it is better to do several short presses rather than one long one.
Another powerful trick is using a brightness mask. Go to the Image menu and select Curves. Lower the top right point of the curve down. This will darken the lightest areas of the photo, effectively “cleaning up” highlights caused by the glare.
For complex cases where the glare is applied to a face or an important object, use a combination of tools. First, reduce the brightness using the Curves tool, and then work out the edges with the Spot tool. This will create a more natural transition.
☑️ Algorithm for working in Snapseed
Don’t forget about the “Healing” tool, which works similarly to “Spot”, but has slightly different blending algorithms. Experiment with both options to understand which gives the best result for a particular type of surface.
Neural networks and AI: removing glare in one click
A revolution in photo processing occurred with the advent of generative neural networks. Applications that use artificial intelligencecan not just cover up the highlight, but actually fill in the information lost underneath it. This is the most effective method today.
One of the leaders in this area is an application Google Photos with a subscription (Magic Eraser function) or specialized services like Retouch. They analyze the context of the image. If the glare covers part of the face, the neural network “knows” how the skin should look in this place and restores it.
The process of use is extremely simple: you circle the problem area, and the algorithm does all the dirty work. The quality of the result is amazing, especially on modern processors with NPU units. Processing takes just seconds right on the device.
| Application | Processing type | Complexity | Price |
|---|---|---|---|
| Google Photos | AI / Manual | Low | Free / Subscription |
| Snapseed | Manual (Clone) | Medium | Free |
| TouchRetouch | Automatic | Low | Paid |
| Lightroom | Professional | High | Subscription |
It is worth noting that neural networks can sometimes “hallucinate”, creating non-existent details. Therefore, always check the result carefully, especially if the photo contains text or complex geometric patterns.
Why are neural networks better than cloning?
Cloning tools simply copy neighboring pixels, which can create a repeating pattern. Neural networks generate new content based on training with millions of images, which makes the result invisible to the eye.
Working with layers in Adobe Lightroom Mobile
For those who want maximum control over the image, there is nothing better Adobe Lightroom. This is a professional tool that has migrated from desktops to mobile platforms. Working with highlights here is done by fine-tuning the light and shadow pattern.
Use the "Light" panel. The slider White (Whites) is responsible for the brightest points of the frame. Reducing it often removes the core of the highlight. The Highlights slider works with a wider range of bright tones. By combining them, you can gently blend the highlight into the overall picture.
Pay special attention to the “Masking” tool. You can create a mask by selecting just the highlight area using a brush or automatic sky/object selection. By applying the correction to only this mask, you will not affect the rest of the photo.
The latest versions have introduced the "Object Removal" function, which works based on AI in a similar way to Google Photos. It is available in a paid version, but gives excellent results when removing complex reflections from windows or shop windows.
⚠️ Attention: Avoid reducing the Shadows parameter too much when working with highlights. This can lead to digital noise (grain) in dark areas, which will ruin the quality of the photo.
Lightroom also allows you to work with color. Often the highlight is not white, but a yellowish or bluish tint. Use the white balance eyedropper by clicking on the neutral gray area next to the highlight to adjust the color temperature of the entire frame.
The main advantage of Lightroom is the ability to non-destructively edit. You can always return to the original state or change the correction parameters even after months.
Prevention: how to avoid glare when shooting
The best way to remove glare is to prevent it from appearing. It sounds cliché, but following some simple shooting hygiene will save you hours of work in editing. Always clean your camera lens first. Fat fingerprints scatter light and create characteristic rays.
Use a lens hood or simply cover the camera with your palm from side light. Even a small visor, created by hand, can completely eliminate stray glare from street lamps or the sun. This is especially true when shooting at night.
Avoid shooting through glass unless necessary. If this is not possible, press the lens firmly against the glass (using a soft tip to avoid scratching) to eliminate internal reflections. Turn on the Pro or Manual mode in the camera for manual exposure control.
- 🧼 Optics cleanliness: Wipe the lens with microfiber before each important shot.
- 🌞 Angle control: Change the position a few centimeters to remove the light source from the frame.
- 📉 Exposure compensation: Reduce exposure manually before shooting to preserve detail in the highlights.
Remember that digital deglare is always a compromise. It inevitably leads to the loss of some of the original information about texture and color. Therefore, prevention remains the most reliable method of obtaining high-quality images.
Frequently asked questions (FAQ)
Is it possible to remove strong sun glare from a person’s face?
It is impossible to completely remove strong overexposure, where the skin has become pure white, since the data is lost. However, you can soften the transition and restore skin tone by using the cloning tools in Snapseed or the retouching function in specialized portrait applications.
Why is there a blurry spot left after removing the highlight?
This happens because the cloning tool takes texture from neighboring areas that may not match the structure. Try changing the cloning source or use AI tools that regenerate the texture.
Does removing highlights affect the quality of the entire photo?
With proper processing, local changes do not affect the overall quality. However, aggressive dimming or heavy blur can make the processing noticeable. Always check the result at 100% magnification.
Which apps are best for Android?
The leaders are Google Photos (for simple tasks and AI), Snapseed (for manual precision work) and Adobe Lightroom (for professional color correction). TouchRetouch is well suited for automatically deleting objects.
Is rooting a phone necessary for high-quality processing?
No, modern applications use the processing power of the processor and algorithms at the application level. Obtaining root access does not provide any advantages in photo processing and may disrupt the operation of some services.
