How to Fix Chromatic Aberration in Photos

5 min read
Quick Answer

To fix chromatic aberration in a photo, upload it to EditThisPic and describe the issue: 'remove the purple fringing on the edges' or 'fix the color fringing along the high-contrast lines.' The AI identifies the misaligned color halos and removes them, leaving clean, sharp edges without the colored outlines. Free, no signup required.

Get Rid of Those Colored Halos in Your Photos

Chromatic aberration shows up as colored outlines—usually purple, green, or magenta—along high-contrast edges in your photos. Tree branches against a bright sky get purple halos. Window frames glow with green fringing. It's a lens defect that even expensive cameras can't always avoid, and it makes otherwise sharp photos look cheap. AI can detect and remove these color artifacts cleanly.

How AI Removes Chromatic Aberration

EditThisPic's AI scans for the telltale pattern of chromatic aberration: colored bands that appear specifically along high-contrast boundaries. It distinguishes these artifacts from intentional colors in the scene, then neutralizes the fringing by desaturating or replacing the aberrant hues along those edges. The result is clean, sharp transitions without any colored halos—and without affecting the real colors in the rest of the image.

Types of Chromatic Aberration

  • Lateral (transverse) CA: colored fringes along edges, worst at frame corners—shows as purple on one side, green on the other
  • Longitudinal (axial) CA: colored halos in front of and behind the focus plane—common in fast lenses shot wide open
  • Purple fringing: bright purple/magenta outlines on backlit edges, especially tree branches against sky
  • Green fringing: green-tinted edges on the opposite side of purple fringing
  • Bokeh fringing: colored outlines around out-of-focus highlights in the background

When Chromatic Aberration Is Most Visible

It's worst in high-contrast scenes: dark tree branches against a bright sky, backlit subjects with bright edges, architectural details against clouds, and any scene where dark objects border bright areas. Fast lenses (f/1.4, f/1.8) shot wide open produce more CA. Cheap kit lenses and phone cameras are also prone. Zooming to 100% on any affected image makes it immediately obvious.

Tips for Best Results

Be specific about the color: 'remove the purple fringing along the tree branches' is better than 'fix this photo.' If the fringing is subtle and only visible when zoomed in, mention that: 'there's green and purple color fringing along the edges when you zoom in—clean it up.' For photos with CA in the corners but not the center, describe the area: 'fix the chromatic aberration in the corners of the image.'

Step-by-Step Guide

1

Upload Your Photo with Color Fringing

Drop your image into EditThisPic. JPG, PNG, or WebP up to 7MB. Photos with bright skies, backlit subjects, and high-contrast edges are the most common candidates.

2

Describe the Fringing

Type what you see: 'fix the purple and green color fringing on the edges' or 'remove the chromatic aberration along the tree branches against the sky.' Mention the specific color of the halos if you can see them.

3

Check the Edges

Zoom into the areas that had fringing. Verify that the colored halos are gone and that edge details remain sharp. The actual colors in the scene should be unaffected.

4

Refine If Needed

If fringing remains in some areas, describe them: 'there's still purple fringing in the top-right corner.' If the fix removed some real color along edges, try 'remove only the purple fringing, keep the natural edge colors.'

Frequently Asked Questions

Upload the photo to EditThisPic and type 'remove the purple fringing along the edges.' The AI detects the chromatic aberration pattern—colored halos along high-contrast boundaries—and neutralizes them without affecting the rest of the image. No manual defringe sliders needed.
Chromatic aberration happens because lenses can't focus all wavelengths of light to the same point. Different colors (red, green, blue) land slightly offset from each other, creating colored fringes along contrast edges. It's worse with cheaper lenses, wide apertures, and at the edges of the frame.
Yes. Phone cameras are especially prone to chromatic aberration because of their small, thin lens elements. The AI works the same way regardless of camera—it detects the colored fringing pattern and removes it. Upload and describe what you see.
Purple fringing is one type of chromatic aberration. CA can produce purple, green, magenta, cyan, or red halos depending on the type (lateral vs longitudinal) and the lens. Purple is the most common and noticeable, which is why people often call all CA 'purple fringing.'
No—it actually improves perceived sharpness. The colored halos from CA make edges look soft and muddy. Removing them reveals the clean, sharp edge underneath. The AI only targets the aberrant color along edges, leaving the rest of the image untouched.
