How to Fix a Dark or Blurry Photo (and When You Can’t)

Be realistic about what you can save

Editing can reveal what a photo captured, but it can’t invent what it didn’t. In practice:

• Slightly dark photo: Usually easy to fix. The details are there; they just need brightening.
• Very dark, nearly black photo: You can recover very little. Brightening it will reveal grain (noise) and color blotches.
• Slightly out-of-focus photo: Sharpening can help bring out existing edges.
• Shaky or very out-of-focus photo: It can’t be fixed. The edges have blurred together, and there’s no information to reconstruct them.
• Blown-out areas (a completely white sky or face): They can’t be recovered. Pure white contains no detail.

AI tools that “restore” photos create new details that look plausible but aren’t real. That may be fine for family photos, but not for documents, evidence, or any use where accuracy matters.

Brighten a dark photo

1. Open Adjust brightness and contrast and select your photo.
2. Gradually increase brightness, checking the preview until important areas (faces, text) are visible.
3. Brightening can make a photo look washed out. Slightly increase contrast to restore depth to darker tones.
4. If the colors look dull, slightly increase saturation. If they look too intense, reduce it.
5. Compare the result with the original. As a rule, stop just before it looks ideal: strong adjustments can look artificial on other screens.

Make a photo sharper

Sharpen image uses unsharp masking, the same technique used in professional editors. It increases contrast along object edges to create the impression of focus. Here are the three controls:

• Amount: How strongly the effect is applied. Start with the default and adjust from there.
• Radius: 1 enhances fine details (text, eyelashes, texture); 3 or higher enhances larger edges.
• Threshold: Ignores small variations, such as sky noise and skin texture. Increasing the threshold helps keep skin from looking rough.

Always check the preview at 100% (actual size). Too much sharpening creates bright halos around edges and brings out noise.

The right order for photo adjustments

1. First, crop and straighten the photo so you don’t adjust areas you’ll remove.
2. Next, adjust brightness and contrast.
3. Sharpen last. Sharpening before brightening brings out noise that will become even more visible afterward.
4. If you’re resizing the image to send it, sharpen it after resizing because downsizing softens the image.

Dark or blurry photo of a document

For documents, the best fix is to retake the photo in good lighting. If that isn’t possible, use the Document Scanner with the document filter. It turns the background white and the text dark, which can often make a slightly dark photo readable. A shaky photo can’t be fixed, though: numbers may be ambiguous and easy to misread.

How to prevent it next time

• In low light, steady your phone or rest your elbows to prevent camera shake. Your phone’s night mode needs a few seconds without movement.
• Tap the main subject on the screen to focus. On many phones, you can also swipe up or down to adjust exposure before taking the photo.
• Clean the lens: a fingerprint can make everything look blurry, and no editing can fix that.
• Take more than one photo. One of them will usually be sharper.
