How to shoot the background blur with SLR?

Question 1: How to set up a camera with a SLR to shoot a blurred background? For example, use the 18-200 lens. Before shooting, Morinda officinalis put the lens at the 200-end with the largest aperture. Focus on close-up figures, and the background is blurred in the distance.

Wide-angle-medium focus bow effect is not obvious.

Question 2: How do SLR cameras take photos with prominent themes and blurred backgrounds? What mode do you usually shoot? Background blur is not in the mode, but the cooperation of aperture and focal length. Give you a rule, the longer the focal length, the larger the aperture, the closer to the focal point, the shallower the depth of field, and the more blurred the foreground and background. Conversely, the deeper the depth of field, the clearer the foreground and background. Remember that the smaller the aperture value, the larger the aperture.

Question 3: How does a SLR camera blur the background? In addition to better image quality, the more powerful depth-of-field control ability of digital SLR is also a great advantage over ordinary digital cameras. This means that with a digital SLR camera, you can easily shoot a portrait with a blurred background, which looks particularly professional. However, many consumers who have bought digital SLR cameras find it difficult to take such photos with their cameras. What is the reason?

That's because, to take a portrait photo with a blurred background, you need a suitable lens besides a digital SLR. We know that a photo with a blurred background means "the depth of the scene". The larger the aperture or the longer the focal length, the shallower the depth of field of the photo. Therefore, taking photos with blurred background must meet at least one of the two conditions of large aperture or long focal length.

In fact, major manufacturers have some special portrait lenses. For example, a fixed-focus lens with a focal length of 85mm and an aperture above F 1.8 is what we call a "portrait head". Of course, a large aperture zoom lens with a focal length of 24-70mm or a focal length of 70-200mm is also suitable for taking portraits. Usually, the focal length of the lens of a digital SLR camera is 18-55mm (or 18-70mm), and the aperture is only F3.5-F5.6, so the blurring effect of the portrait background shot with this lens is very limited.

But it should be noted that in the actual shooting process, the larger the aperture, the better. This is because, first, the image quality will be better if the lens aperture is reduced. (Related links: What is the best imaging aperture of the lens? ) For example, if we take a portrait with an 85mm lens with an aperture of F 1.8, we will find that the image quality of this lens with an aperture of F2.8 is better than that with an aperture of F 1.8, which is characterized by clearer image and higher resolution. In addition, if the aperture is too large, it is easy to make the depth of field very shallow. Sometimes, the focus is on the nose and the eyes may be blurred. This can be avoided by narrowing the aperture. So in the process of shooting, we don't have to choose to shoot with the maximum aperture of the lens. It is a better choice to narrow the aperture by one or two steps.

What if we don't have a large aperture lens? A telephoto lens is also a method. Although a lens like 70-300mm F4.5-5.6 has a small aperture, it can get a better background blur effect because of its long focal length. But at this time, the photographer should stay away from the subject (if he is close, he can only take a big picture), which requires higher shooting stability, because a long focal length requires a faster safety shutter to ensure shooting stability.

Question 4: How to set up a SLR camera to take photos with blurred background? It's simple. Remember that large aperture+long focal length+close-range shooting = maximum background blur.

Question 5: How to adjust the SLR camera to take photos with blurred background? This phenomenon you are talking about is called shallow depth of field, which means that the depth of the scene is small, so the foreground is clear and the background is blurred. There are three main conditions to realize shallow depth of field: 1 and aperture. The larger the aperture, the smaller the aperture value and the smaller the depth of field. The effect is not obvious. 2. focal length. The greater the focal length, the smaller the depth of field. The effect is obvious. 3. Object distance. The closer the camera is to the subject, the smaller the depth of field. The effect is very obvious. Therefore, according to Sichuan method, when shooting, you should use the largest aperture and the longest focal length, and then try to get close to the subject under the premise of both, and then try to keep the subject away from the background. This effect must be what you want, hehe. Pick up the camera and try it now!

Question 6: SLR shoots people with blurred background. How to set the phenomenon you mentioned is called shallow depth of field, that is, the depth of the scene is small, so the foreground is clear and the background is blurred. There are three main conditions to realize shallow depth of field: 1 and aperture. The larger the aperture, the smaller the aperture value and the smaller the depth of field. The effect is not obvious. 2. focal length. The greater the focal length, the smaller the depth of field. The effect is obvious. 3. Object distance. The closer the camera is to the subject, the smaller the depth of field. The effect is very obvious. Therefore, according to the above rules, when shooting, you should use the largest aperture and the longest focal length, and then try to get close to the subject under the premise of both, and then try to keep the subject away from the background. This effect must be what you want. Besides, the photo of car optical flow you mentioned is very simple. As long as the ISO is set to 100, the aperture can receive about F8, and then put it on a tripod for a long time exposure. The exposure time can generally be about 4~8 seconds, depending on the actual light conditions.

Question 7: How does a SLR camera take photos with the following effects? Blurred background and prominent characters? How to set it? What kind of camera are you?

Question 8: How do SLR photos show the illusory effect of clear background of characters? Please note the following points:

1. Adjust the aperture to a smaller value (such as F3.5). In this way, the background blur will be high;

2. Use a longer focal length (such as 18- 135 lens, and choose 135 end to shoot), so that the background blur is high;

3. Bring the camera closer to the subject (the photographer is close to the subject). In this way, the background blur is high.

As long as you make good use of these three points (single use and mixed use), you can shoot the blur effect you need.

Question 9: How does a SLR camera blur the background? The background of the photos taken by SLR camera is blurred;

1: When shooting with a medium telephoto or telephoto lens, the longer the focal length, the better the blur;

2: Use aperture priority (A) mode and try to shoot with the maximum aperture;

3. When shooting, the camera should be as close to the person as possible, and try to close the distance between the person and the background after ensuring the required distance for composition.

Satisfied with my answer, please adopt it in time!

Question 10: How does a SLR camera take photos with prominent themes and blurred backgrounds? What mode do you usually shoot? Background blur is not in the mode, but the cooperation of aperture and focal length. Give you a rule, the longer the focal length, the larger the aperture, the closer to the focal point, the shallower the depth of field, and the more blurred the foreground and background. Conversely, the deeper the depth of field, the clearer the foreground and background. Remember that the smaller the aperture value, the larger the aperture.
