Topic: Effective and easy way to sharpen a blurry photo
Sometimes insufficient sharpness can ruin an otherwise great photo.
There are several causes of blurring in digital photos: probably your hands were shaking, or the object was moving while the shutter was open, or the camera could not focus properly.
Pho.to site offers a smart algorithm that performs automatic deblurring with impressive results. To improve a photo that needs to be sharpened, use the Deblur tool in handle_url_tag('http://editor.pho.to', 'Online Photo! Editor') service.
First of all, upload a photo that needs to be sharpened (from your computer or from the Internet):
When your photo is uploaded, click the Deblur button (in the Correct photos section):
The sharpening effect can be controlled with the Strength and Radius sliders (you will find them above the image):
The strength defines how obvious the sharpening effect will be. Higher strength will result in more sharpening.
The radius determines the area that will be sharpened. With a low radius, only the pixels right next to the edge will be sharpened. With a high radius, a wider area will be sharpened. Setting the radius too high will give you weird outlines around edges.
Tip: Radius and strength work together. If you sharpen with a larger radius, you might need less strength than if you sharpen with a small radius.
This is the result that the tool showed with one of our photos:
