Ask: How to take photos with blurred background and prominent subject with Pentax kr? Thank you for your guidance!

If you want to take a photo with a blurred background, you should pay attention to the following points:

1, distance between the subject and the background, that is to say, there should be no other subjects around people, such as standing in the middle of an unmanned playground, then this person is far away from the background (buildings on the edge of the playground), and it is better to take photos with blurred background.

2. Try to use the 55mm end, because the 18 end is wide-angle and the depth of field is relatively large, so it is difficult to take photos with blurred background. Even if there is, the effect is not obvious.

3. Try to keep the camera close to the subject, which is complementary to the first one. Generally speaking, however, the focal length of the lens is the closest, so try to get close to the subject within the allowable range. This is the best way to blur the background, and several people upstairs have also talked about it.

In summary, the hardware elements with blurred photo background are as follows:

1, telephoto. This is the most effective way to blur the background. Whether you use a large aperture lens or not, once the focal length of your lens is above 100, it is easy to get a picture with a blurred background by paying a little attention to the distance between the subject and the background.

2, large aperture. Theoretically, large aperture will bring shallow depth of field, but large aperture lenses are generally more expensive and the effect is not as good as telephoto, mainly because large aperture is difficult to control and easy to blur. Of course, telephoto+large aperture is the best, but this kind of lens is generally surprisingly expensive.

The ambiguity at the end of LS, 1855, and the ambiguity at the end of 55 is good. Although the aperture is not large, it is well controlled. This blur is more delicious than the blur in the cow's head, because the background can still be seen clearly, and it is of little significance to really blur the background.
