There are three factors that affect the blurring of background: photography is necessary.

Even if many babies have cameras, they can't take the effect of blurring the background. Why?

There are three main factors that affect the blurring of shooting background:

1. Shooting aperture setting

2. Adjustment of shooting focal length

3. The distance between the subject and the background

The blur degree of shooting background is mainly related to these three factors ~

1. hole

The smaller the aperture value, the larger the aperture and the more blurred the background.

The larger the aperture value, the smaller the aperture and the clearer the background.

2. Focal length

The smaller the focal length, the wider the shooting range and the clearer the background.

The larger the focal length, the narrower the shooting range and the more blurred the background.

3. The distance between the subject and the background

The farther the subject is from the background, the better the blur effect.

The closer the subject is to the background, the worse the blur effect is.
