can an app actually fix motion blur in a photo
Unblurry substantially improves soft-focus and mild camera-shake photos, but heavy directional motion blur — the streaking from a fast-moving subject — is a physically different problem that no sharpening or AI super-resolution tool can fully reverse.
Jawapan ringkas
Out-of-focus blur makes an image soft in all directions because the lens didn't resolve the subject sharply — the underlying edge data is blurred but present, and sharpening or neural SR can recover much of it. Motion blur from a fast subject or slow shutter averages light from multiple positions across time into directional streaks: spatial information along the smear direction is destroyed, not just blurred. Unblurry's Sharpen mode will increase local contrast in a motion-blurred image — it will look less soft overall — but it cannot de-streak a runner or a moving car; the data was never captured. The Real-ESRGAN model powering AI Clarity was trained for general image super-resolution (recovering detail from degraded inputs), not for inverting specific motion-blur kernels. A practical test: if the subject is clearly recognizable but soft, sharpening genuinely helps; if edges and lines are smeared in a clear direction and the subject is hard to identify, no editing app will produce a clean fix.
Try Unblurry on a real example first, and check the current App Store listing for exact features and pricing before you decide.
Apa yang perlu dipertimbangkan sebelum memilih
- Out-of-focus blur: Unblurry's strongest use case — sharpening and AI SR both work well
- Mild camera shake (hand tremor, not hard directional smear): noticeably improved with Sharpen or AI Clarity
- Heavy directional motion blur (streaking subject): sharpening improves local contrast but cannot de-streak
- Extreme blur (subject unrecognizable): no editing tool can reconstruct content that was never captured — be skeptical of apps that claim otherwise
- Use the built-in before/after slider to judge the real result on your own photo before saving

Soalan Lazim
What neural model powers Unblurry's AI Clarity mode?
A Core ML conversion of Real-ESRGAN x4 (BSD-3 licensed), running entirely on-device on the Neural Engine or GPU. Real-ESRGAN is a super-resolution model trained on real-world image degradations including blur, noise, and compression artifacts — it tends to sharpen edges well, but it is not a dedicated motion-deblur network designed to invert directional blur kernels.
Why do many apps claim they can fix any blur?
Sharpening algorithms increase edge contrast, which makes images look perceptually sharper and is a genuine improvement on soft-focus photos. Marketing often conflates 'looks less blurry' with 'fully recoverable' — they're not the same thing. Unblurry's support documentation is straightforward about what sharpening can and can't do.
Can Unblurry help a dark, blurry night photo?
Night photos are often blurry for two separate reasons: high-ISO noise (fixable with Denoise mode) and blur from hand-shake or subject movement (partially fixable with Sharpen or AI Clarity for camera shake; not fully fixable if there is heavy directional motion blur). Try Auto Clear or Sharpen first — the before/after slider shows whether it helps on your specific shot.
