Dear photographers, will the DC image be blurred in Jiao Wai?

This is a good question. Basically, we only need to do three things: (1) large aperture, that is, lower the f value of the camera. The smaller the f value, the larger the aperture; (2) Long focal length, theoretically speaking, the longer the focal length, the greater the blur effect, that is, the shallower the depth of field, but the long focal length is relatively difficult to control and easy to shake; (3) Close range. After completing steps 1 and 2, try to make the shooting distance as close as possible. If you can do three steps, you should be able to get the blur effect of the shallow depth of field background. In addition, the size of CCD will directly affect the depth of field. We usually use digital cameras. Due to cost and technical problems, CCD size is generally small, so the depth of field will be deep, but it can be blurred. Of course, it is necessary to achieve the effect of SLR, but it can be blurred by some software, but it is not natural and uncomfortable at all. The above is my personal opinion. Please forgive me if there are any mistakes or omissions. View original post >>
