To blur a photo for a story, you could start by opening the photo in an image editing program. Then, find the filter or effect section and select the blur option. You might be able to choose between different types of blur, like Gaussian blur or motion blur, depending on the effect you want. Play around with the settings until you get the desired blurring effect.
You can use photo editing software like Adobe Photoshop or GIMP. Open the image, select the face area, and apply the blur effect. It's quite straightforward.
There are several ways. One common method is to use photo editing apps on your phone. For example, apps like Snapseed or VSCO have blur tools. You select the background area and choose the blur intensity.
