How does Nikon D3 100 take photos with hazy background? Seek high marks

Even the 18-55vr lens for the crew? This head can shoot films with blurred background. First, you should set the shooting mode to manual mode, that is, M mode or aperture priority mode, that is, A mode, and then aim at the object you want to shoot for as long as possible to make the lens blur better. Adjusting the aperture can only be done in these two modes, that is, press the shutter gently first and then dial the wheel in front of the camera. That is to say, you can see the electronic number F+ through the viewfinder with your index finger, such as f3..5 f5.6 and so on. The smaller the number, the larger the aperture and the higher the background blur. The larger the number, the smaller the aperture and the lower the background blur. If you want to take a blurred picture, use mode A. You can't even figure out the manual camera adjustment, and the sensitivity of shutter adjustment is more complicated. If you can't understand it at the moment, you can use a mode and then set the aperture, that's all. Try not to turn on the flash. Ok, remember to give me extra points when you study. Ha ha.
