How to shoot clearly by manual focusing?

Question 1: SLR cameras use manual focusing when shooting close objects. Why do photos always blur objects? How can I get a clear picture? 1, it may be out of focus, so it is impossible to focus.

2. Manual focusing is not allowed.

3. Shake, and turn off the anti-shake function when using the tripod.

4. Choose the appropriate close-up, fix the camera with a tripod, and observe or enlarge the screen with the LCD screen for convenient and accurate focusing.

Question 2: Why do you see clearly in the lens when you take a picture with manual focus, but it is blurred and out of focus at all? Besides being out of focus, your hands may shake.

Regardless of whether manual focusing is accurate or not, you should overlap the focus with the object you want to focus on. After focusing, the observation window has a "focus prompt". For example, Nikon will have a bright spot in the lower left corner. If it is not in focus, left and right arrows will appear to indicate whether it is far or near.

Not just because the eyes can't see clearly. The resolution of the picture seen by the eyes is not as large as that of the computer screen, and it may not look completely aligned at low resolution.

Question 3: How to screw the manual focus ring of Canon 550d most clearly? How to focus the Canon 550d manually is the clearest:

1: When high focusing accuracy is required, use a tripod to stabilize the camera;

2: set the mode dial to any gear of P/Tv/Av/M, and set the AF/MF switch on the lens to MF;

3. Press the real-time display shooting button, press the up, down, left and right buttons to move the focus frame to the position where you want to drink coke, press the zoom button to enlarge the image to 10 times, and rotate the focus ring of the lens while watching the enlarged image. When the focus is clear, you can shoot.

Satisfied with my answer, please adopt it in time!

Question 4: When taking a portrait, focus manually and adjust the focus ring clearly, but the photos taken are still virtual. How to solve the focus problem? Since the focus is not touched, it is because the shutter speed is too low, so the character is weak. When the shutter speed is too low (below 1/30 seconds), hand-held shooting will be weak due to jitter, so you should use a tripod to shoot at this time.

Question 5: How should Canon SLR cameras focus correctly when focusing manually? Are there any tips for taking pictures of beautiful people (blurred background)? Manual focus usually has a prompt tone, and if it is good, there will be a beep. Yes, there is a red dot flashing in the focus. You can zoom in on the camera to see if it is clear. Be sure to zoom in. First press the shutter half to focus, don't let go of your hand, then compose the picture, and then press the shutter when the picture is finished.

Question 6: How to accurately align the manual focusing of photos? I don't know what machine you are using. If it is a SLR, the manual focus autofocus screen will generally have a focus display after focusing, whether it is on or off. If you want to determine the focus entirely by yourself, it is generally recommended to enlarge the picture. You can use a larger viewfinder to enlarge the picture, or you can directly project the picture on the display screen to select the enlarged picture. Generally 5- 10 times magnification will be very clear.

Question 7: How to shoot the product clearly? 1. tripod. Many articles on photography technology suggest that photographers should pay attention to the use of tripods, and no element has such a great influence on image quality. But if you use a tripod, you must use a high-quality tripod, and don't play the wishful thinking of "replacing the high-end tripod with a cheap tripod." The tripod with high cost performance, each leg can be opened independently, with reasonable weight, stability and reliability, and convenient use. With a high-quality tripod, you have to have a matching tripod. The tripod is stable, the tripod is unstable, and the whole system is still unstable. A good pan-tilt should not only be stable enough, but also be able to load and unload quickly, which is suitable for all kinds of subjects. When using a tripod, it is best to only rise to the necessary height. Unless absolutely necessary, it is the last choice to raise the center column, because the center column is not a triangular braced stable structure, which greatly increases the unstable factors. In addition, in windy weather, it is best to reinforce the tripod with heavy objects.

2. Shutter speed. Don't be fooled by the bright sunshine, please remember the basic rule of hand-held photography: the shutter speed is the reciprocal of the focal length of the lens. Of course, this is a rule of thumb. If you want to get high-definition photos, you need a higher shutter speed. Even every time the heart beats, the flow of blood in the body will cause hand tremors. Most photographers don't think that heartbeat will affect the imaging quality, but according to relevant calculations, the pulse will cause a displacement of about 0.2 mm, so the shutter speed should not be lower than110 second at least. If you use a high-quality lens with a resolution of 100 lpm, if you use a shutter speed of 1/250 seconds for hand-held photography, even if the displacement is 0.2 mm, its resolution will be reduced to 78 lpm, with a resolution loss of about 22%. If the shutter speed is further changed to 1/60 seconds, the resolution is only 30 lpm. Therefore, don't believe that a 60mm Nicole macro lens for hand-held photography, with a shutter speed of 1 /60 seconds, can take photos that are enlarged enough to be more than 10 inch. Many times, the sharpness is not enough not only because the camera is moving, but also because the subject we shoot is moving, such as the branches blown by the wind, the people on the stage and so on. In this case, even a tripod can do nothing, and a faster shutter speed is needed to ensure the clarity of the picture.

3. Cable release. Don't think that putting the camera on a tripod will be done once and for all. You know, no matter how light the shutter is, it will cause vibration. The problem of machine vibration can be minimized by using cable release and pre-lifting function of reflector. If there is no cable release, please use the camera's * * * instead. Although it is not as good as cable release, it is still much better than touching it by hand.

4. Focus accuracy. Although the scenes in the depth of field are within the clear range acceptable to the eyes, if you enlarge the photo, you can still see the sharpness difference between in-focus and out-of-focus, so if you want to get satisfactory sharpness, don't just focus because the depth of field is large enough. There will always be errors in autofocus. If time permits, manually focus on the topic you want to express most.

5. Use the best aperture. The resolution and sharpness of each aperture of a lens often vary greatly, sometimes by one or two apertures, and the sharpness is like a world of difference. Using the "best aperture" of the lens is an important means to improve the sharpness. Generally, the best aperture of a lens appears in the middle aperture, and the imaging with large aperture and small aperture is not good. For example, Nikon 16-85mm F3.5-5.6 lens, the best imaging is in F8- 1 1, while the middle aperture of large aperture lens is smaller, and the optimal aperture is smaller, for example, the optimal aperture of 50/F 1.8 is in F5.6, and the top zoom lens. However, although the small aperture has a large depth of field and the center and edge of the image quality are relatively uniform, the resolution will be worse than that of the large aperture because of the serious diffraction problem. Therefore, in order to ensure the clarity of the image quality, we should try to avoid shooting with the minimum aperture.

6. lens. If you do well before 5 o'clock, I believe that you can get photos with good definition in most cases. But if you have professional needs, don't forget to buy professional lenses-although many times, they are not better than ordinary lenses ... >>

Question 8: The camera focuses manually during the shooting process. How to make the whole shooting process worthwhile? This shooting method is called "following focus".

This needs to be done through follow focus.

It is a standard position to follow the focus clerk.

It has nothing to do with distance, but with focal length.

If you put it in a wide angle, it is easier to follow.

Telephoto is more difficult.

Question 9: Q: How to focus manually when shooting night scenes? Exposure selection

Exposure is particularly important for night shooting. For digital cameras with only night view mode and no manual exposure control, we will have other methods to adjust them.

For digital cameras with manual exposure control, we usually choose A mode (aperture first) or M mode (manual mode) to shoot at night. The instant shooting and display function of digital camera allows players to judge the effect of exposure combination in the shortest time, which is quite convenient to adjust.

When shooting at night, the author usually sets the f value to the maximum and then adjusts the shutter, so that the picture effect can be seen directly from the LCD screen. The choice of exposure time is technically limited by the parameters of the digital camera itself, and the other is different from person to person in creation. The compromise is to use a variety of exposure combinations to shoot, and then screen later.

The effect of long exposure is still attractive, especially if you want to show a brilliant night, you need long exposure to complete it. Of course, the assistance of tripod is essential. In order to obtain the towing effect caused by traffic, the shortest exposure time should not be less than 15s. Of course, experienced players can also manually control the exposure time with door B, so that the photos taken are full of fluidity.

Using simple night scene mode is far from meeting the needs of photography creation. Making full use of the existing functions of digital cameras to get more fun in shooting is our next theme. In fact, it still involves those terms we often encounter-focus, exposure, ISO, flash and so on. Let's first look at a common problem: shooting portraits at night and turning on the built-in flash to assist shooting. However, the portrait was taken clearly, but the beautiful night scene behind us was gone. How to solve it!

Note: After the built-in flash is turned on to assist shooting, the digital camera will automatically increase the shutter speed, which makes the background with weak light not well displayed in the photo due to insufficient exposure time. The pleasure of manual focusing

Let me talk about the skills under autofocus first. Because it is difficult for ordinary digital cameras to accurately focus on scenes with low contrast and low brightness, and the night scenes they shoot are often in such an environment, when shooting night scenes, we should try to focus on the bright scenes first, and then lock the focal length for composition, especially when creating portraits at night, which can improve the shooting success rate.

Manual focusing can play an effective role in shooting portraits at night and improve the success rate of shooting.

However, when shooting at night, autofocus is often insufficient, so it is very beneficial to use a digital camera with manual focus to shoot at night. The common manual focusing of digital cameras includes digital adjustment and focusing ring. Digital manual focusing can achieve accurate focusing by adjusting the distance value on the LCD screen, which can play a considerable role in shooting night scenes.

Look at the focusing effect through the LCD screen, roughly estimate the distance between the scene and the camera, and then select the appropriate focal length through the numerical display on the display screen. If you want to show a big scene or a distant scene, you can directly adjust the focal length to infinity, which can achieve the goal well.

For ordinary night shooting, clear focusing is an important guarantee for a successful photo, but for the creation of characteristics, different effects can be evolved in focusing and more fun can be obtained, so I will not discuss the choice of exposure in depth in this article for the time being.

Directional thinking on breaking the white balance

White balance is a major feature of digital cameras, especially when shooting at night, choosing different white balance will directly affect the color tone and artistic conception of photos, because the light generated by floodlights of buildings and scenery at night can present more colored light on digital cameras than the naked eye.

Therefore, when shooting at night, we should break the automatic white balance that we have always relied on, which will affect the inherent color of light and make it lose its unique color temperature feeling. In order to highlight colorful lanterns, you can set the white balance to "daylight" or "outdoor" mode. Of course, trying to shoot with different white balances will have unexpected effects.

A sensitive issue

The sensitivity (ISO) of digital camera also plays an important role in night scene shooting, which is always accompanied by positive and negative results. Increasing the ISO value can improve the shutter speed, which is beneficial to the stability of shooting and reduces the difficulty of shooting. At the same time, the noise increase caused by the improvement of ISO is often obvious. For those without manual exposure control >>

Question 10: How to take a photo with accurate and clear focus? There are many reasons. First of all, the camera lens you use is fixed focus 85, which is what enthusiasts call a portrait lens. Generally speaking, it won't affect you. Secondly, your body image may be insufficient. Blurred photos have many aspects, such as exposure, outdoor and indoor. If the exposure is insufficient, you need to slow down, or enlarge the aperture to slow down. Your hands may shake and the aperture may be blurred. There is no time. Give points first!

The magnification aperture is mainly due to the larger depth of field, and the aperture is 85 1.8. I suggest that the aperture should not be lower than 5.6. There is no special effect.

I suggest you shoot in a larger format, which will help you find the mistakes made in the early stage and make it easier to correct them later.
