Lens flare happens when stray light enters the lens and bounces between internal glass elements before hitting the sensor. The result ranges from subtle contrast loss across the entire frame to dramatic geometric ghosts, colored streaks. Bright polygonal shapes that overlay your subject. While some photographers use lens flare intentionally for artistic effect, unwanted flare is one of the most common reasons an otherwise excellent photo is unusable. It washes out colors, obscures important details, and draws the viewer's eye to the artifact instead of the subject.
Flare is mainly problematic in backlit portraits, golden hour landscapes, street photography near artificial lights. Any situation where a strong light source sits near or within the frame. DPReview documents how even modern multi-coated lenses produce flare under certain conditions. The problem is greatly worse with older lenses, dirty glass, or when shooting without a lens hood. The physics of light bouncing between glass elements means that prevention — while helpful — cannot eliminate flare fully.
AI photo editing tools offer a practical solution for removing lens flare after the fact. Magic Eraser targets discrete flare artifacts like ghost spots and streaks, AI Fill reconstructs subject detail that flare has obscured. AI Enhance restores the contrast and color accuracy that veiling flare degrades. This guide covers how to identify different types of flare, match each type to the right removal tool. Produce a clean result that looks like the flare was never there.
- Magic Eraser removes discrete flare artifacts — ghost spots, polygonal shapes, and colored streaks — by reconstructing the scene beneath them.
- AI Fill regenerates subject detail lost under large flare areas, including faces, textures, and architectural elements.
- AI Enhance restores the contrast and color saturation that veiling flare washes out across the frame.
- Different flare types require different removal approaches: ghosting needs targeted erasure, veiling flare needs contrast restoration, and lost detail needs reconstruction.
- The technique works on flare from any source — sunlight, streetlights, headlights, stage lighting, and window glare in interior shots.
Understanding the types of lens flare
Not all lens flare looks the same. Identifying the type you are dealing with determines the most effective removal strategy. Veiling flare is the most subtle and pervasive form. It appears as a general haze or contrast reduction across part or all of the frame. The image looks washed out, with lifted blacks, reduced color saturation, and a milky quality in the affected area. Veiling flare occurs when light scatters broadly across the lens elements rather than forming discrete reflections. It is often hardest to detect because it does not produce a visible artifact. It simply degrades the image quality.
Ghosting is the most visually distinct form of flare. It produces distinct shapes — circles, hexagons, pentagons, or other polygons matching the lens aperture blade count — that appear in the frame, usually in a line extending from the light source through the center of the image. These ghosts are internal reflections of the light source bouncing between lens elements. They often appear in matching colors to the original light: a warm sunset produces cool blue or purple ghosts. Ghosting is common in backlit scenes, golden hour photography. Any image where the sun or a bright artificial light is near the frame edge.
Starburst patterns and anamorphic streaks are the third category. Starbursts radiate outward from point light sources — streetlights, candles, Christmas lights — and become more pronounced at smaller apertures. Anamorphic streaks are horizontal light smears associated with certain lens types, mainly older or specialized cinema lenses. Both types can be intentional artistic choices or unwanted distractions depending on the context. Lensrentals has documented how these artifacts vary greatly between lens designs, coatings, and aperture settings.
- Veiling flare reduces contrast and washes out colors without producing a distinct visible shape — it degrades the whole affected area.
- Ghosting creates geometric shapes (circles, hexagons, polygons) in a line from the light source through the frame center.
- Starburst patterns radiate from point lights and intensify at smaller apertures.
- Identifying the flare type determines whether you need targeted removal, detail reconstruction, or contrast restoration.
Removing ghost spots and discrete flare artifacts
Ghost spots and distinct flare shapes are the most straightforward to remove because they have clear boundaries. Open the affected image in Magic Eraser and brush over each ghost artifact one by one. The AI analyzes the image content surrounding the artifact. Sky gradient, cloud texture, foliage pattern, building surface — and reconstructs what the scene looks like without the flare overlay. For ghosts that appear against a fairly uniform background like blue sky, the removal is nearly invisible on the first pass.
Work from the smallest and most isolated artifacts first. A small ghost spot sitting in an open sky area is an easy removal that produces a perfect result. Build confidence with these before tackling larger ghosts or those that overlap with important subject detail. When a ghost sits on top of a complex background. Tree branches, architectural detail, a person's clothing — the removal is still effective but may need a touch-up pass. After the first removal, zoom in and check whether the reconstructed area matches the surrounding texture and color.
For flare streaks and elongated artifacts, trace along the full length of the streak with the Magic Eraser brush rather than trying to remove it in sections. The AI produces a more coherent reconstruction when it processes the entire artifact as a single removal operation. If the streak passes through multiple background types. Starting in the sky, crossing a roofline, and ending on a building facade — remove the sky portion and building portion separately so the AI can apply right reconstruction to each surface type.
- Brush over each ghost artifact individually — the AI reconstructs the sky, landscape, or surface beneath it.
- Start with small, isolated ghosts against uniform backgrounds for the cleanest results, then tackle complex areas.
- Remove elongated streaks in a single brush stroke along their full length for coherent reconstruction.
- When streaks cross multiple surface types, split the removal into sections so the AI reconstructs each surface appropriately.
Recovering detail lost under large flare areas
The most challenging flare removal involves large areas where the artifact obscures important subject detail. A veiling flare washing across half a portrait, a bright ghost sitting directly over an architectural feature, or a broad light bleed covering product detail in a commercial shot. These cases require reconstruction, not just removal. AI Fill handles this by generating plausible content based on the visible portions of the subject and the surrounding context.
When using AI Fill for flare-damaged areas, select generously. Include enough of the undamaged subject around the flare zone that the AI can understand the structure it needs to reconstruct. For a portrait with flare across the left side of the face, select the entire flared area plus some of the visible right side so the AI has reference for skin tone, facial features, and lighting direction. For architectural detail obscured by a ghost, include the visible portions of the pattern or structure above and below the affected area.
PetaPixel notes that post-processing correction of light artifacts has improved greatly with AI tools, but expectations should match reality. AI Fill can reconstruct plausible texture, pattern continuation, and consistent color. But it cannot recover information that was completely destroyed by blown-out highlights. If the flare area is pure white with zero detail, the AI generates what should be there based on context rather than recovering what was there. For critical work, compare the reconstruction against reference photos or revisit the location to reshoot.
- AI Fill reconstructs subject detail — faces, textures, patterns — that flare has obscured or washed out.
- Select generously around the flare zone so the AI has sufficient undamaged reference for accurate reconstruction.
- Blown-out highlights with zero detail are generated from context rather than recovered — results are plausible but not exact.
- For critical work, compare AI reconstructions against reference photos or reshoot the scene without flare.
Restoring contrast and color after flare removal
Even after removing discrete flare artifacts, the image may still show the effects of veiling flare. Reduced contrast, lifted shadows, desaturated colors, and a general lack of punch compared to a flare-free capture. AI Enhance addresses this by analyzing the image's tonal range and restoring the contrast and color that the stray light degraded. The correction is intelligent: it deepens shadows that the flare lightened without crushing detail, increases color saturation without oversaturating areas that were not affected, and restores a clean black point.
Apply AI Enhance after all artifact removal is complete. Running it first would strengthen the flare artifacts along with the rest of the image, making them harder to remove. The sequence is: remove discrete artifacts with Magic Eraser, reconstruct lost detail with AI Fill if needed, then apply AI Enhance as the final polish. This sequence produces the most natural result because the boost operates on a clean image that no longer contains light contamination.
For images where veiling flare affected only part of the frame. Common when the light source is off to one side — the AI Enhance pass may produce a visible boundary between the corrected area and the unaffected area. If this happens, a targeted adjustment to the contrast or exposure in the transition zone smooths the boundary. The goal is an image where the viewer cannot identify where the flare was. Means the corrected area must match the unaffected area in both tonal character and detail quality.
- AI Enhance restores the contrast, shadow depth, and color saturation that veiling flare degrades across the frame.
- Always run AI Enhance after artifact removal — enhancing first would strengthen the flare artifacts and make them harder to remove.
- The correction sequence is: Magic Eraser for artifacts, AI Fill for lost detail, then AI Enhance for contrast and color restoration.
- Check for visible boundaries between corrected and uncorrected areas and smooth any transitions for a seamless result.
