How to deal with ambiguity clearly?

How to deal with blurred pictures is as follows:

You can use ps software, open ps software, drag blurred pictures into the software, and copy the picture layer on the layer. Click on the filter guide above, select Other, then select Gao Fancha Reserve, adjust the radius pixel to a suitable size in the pop-up window, click OK, click the normal button on the layer, and select Overlay.

The reason why the picture is blurred:

1, back focus

This is the easiest thing to happen. When the camera is in auto-focus, the focus tends to be behind the focus target, and the focus and periphery become blurred. Especially in macro and long-distance shooting, it is easy to happen. It is suggested that you can enlarge the focus area in live view mode and then press the shutter.

2, hand-held shooting shutter is too slow

1/ lens focal length = hand-held shooting safety shutter. For example, if you have a 30mm wide-angle lens, then you need at least a shutter speed of 1/30 seconds to ensure its clarity; If you use a 200mm telephoto lens, it will take about 1/200 seconds to hold it.

For many photographers who like to shoot in aperture priority mode, they are often forced to accept the time below these safe shutters without paying attention to the shutter speed.

3. The shutter speed for shooting moving objects is insufficient.

In the daily light during the day, it takes 1/250 seconds to photograph people walking; The movie takes about 1/500 seconds ~11000 seconds to run. For other sports, you may need to use a higher shutter speed.
