In this modern times, you can fix blurry digital photos by using a computer. You'll need a software, called an image editor, to sharpen your blurry digital photos.
So how can an image editor help fix blurry digital photos?
Most image editors correct blurry photos by increasing the contrast between pixels. And depending on the image editor you use, here are some of the sharpen features you can choose from:
1. Sharpen filter. Most image editors have this feature. This filter is used to fix blurry digital photos by increasing the contrast of adjacent pixels.
Here's an example...
blurry photo sharpen filter filter twice
The left-most image is blurry because it is out-of-focus. When you click the sharpen filter once, the photo becomes sharper as seen in the middle photo. But don't overdo the sharpen filter or else your edited photo will become grainy or pixelated like the third photo. It was sharpened twice.
2. Sharpen Edges or Unsharp mask. Use Sharpen Edges if you want to sharpen just the edges in your photo while retaining the smoothness of the rest. If you want more professional correction, you might want to use Unsharp Mask instead by entering the amount, radius, and threshold.
Take a look at these pictures:
sharpen edges twice
The photo on the left was sharpened using sharpen edges. Notice that only the edges are sharpened while the pixels inside are still the same. But look at the middle photo, similar to the sharpen filter, when you overdo the sharpen edges, digital noise is introduced. In this case, bright halos appear at the edges of the photo.
As for the unsharp mask, when it's applied correctly, it sharpens like the sharpen edges filter. Otherwise, it can look like an over application of the sharpen filter.

3. Manually sharpening selected areas. If you want to sharpen selected objects or features in your photo, click on the sharpen icon and while holding down your left mouse button, move it back and forth over the object you want to sharpen.
Take a look at the menu and toolbars of your image editor to see which of these sharpen filters are supported.
Also, many image editors have a slider or a text box where you can enter the amount of sharpness you want. If there is no slider or text box for manual adjustment, you can click the sharpen filter repeatedly until you are satisfied with the sharpness of your digital photos.
Here's a tip before you use the different sharpen tools to fix blurry digital photos: enhance your digital photos first, and then sharpen. Increasing the color contrast makes your digital photos appear sharper.
But keep in mind that the above sharpening methods are only applicable if your digital photos are slightly blurred. What if you want to fix blurry digital photos that are beyond your image editor's capabilities? Then you might want to use a software that is especially designed to fix blurry digital photos such as Focus Magic.
