Blurry faces in your pictures come from different things, such as lousy camera focus or motion blur (subject moved during the shot), so we need to eliminate blur. With photo editors online apps, such as Google’s Picasa or the open-source GIMP, Corel’s Paint Shop Pro, or Adobe’s Photoshop, you can sharpen a blurred picture and restore your image.
- Apply a sharpening filter.
To eliminate blur, you can use any online photo editor that includes a sharpening tool to increase the contrast between the pixels in the photo. This tool will remove some of the blurriness. It also may introduce graininess if your image is over-sharpened.
- Use an unsharp mask
If your app supports it, use the unsharp mask to control the sharpening process to eliminate blur. The apps featuring an unsharp mask give you control over the specific zones you want to sharpen them.
- Resize your photo
Choose the sharpen edge tool if the image becomes too grainy. The tool will sharpen only the edges of your photos. These are the edges between the face and the background and the lines of facial features. The method will not introduce graininess artifacts in other zones of your picture. Sometimes you can see the blur when you look at the image full size. To eliminate blur, you can hide the blurriness resizing the photo to a smaller format. You need to make a few tests before establishing the best dimension for your image to hide the blurriness.
