How to take clear photos?

Many people will have questions when they buy a SLR camera for the first time: How to take clear photos? All the photos taken with the newly bought new SLR camera don't seem to bring any fun, because the photos are unclear, unclear and blurred. How to avoid this situation? How to make photos clear? This is what we are going to talk about today. You will get clear and charming photos.

The main reasons for unclear photos:

The focus of error is the most common problem for most people. The focus error of the camera may cause the photo to be blurred. This usually happens when you are too close to the subject, or you don't set the correct exposure, or you shoot too fast, so the camera doesn't have time to focus automatically.

The theme is moving, which is another common mistake of photographers. When shooting moving objects, inexperienced photographers usually get blurred photos.

"Jitter"-This term usually refers to the camera shake in the hand. For example, professional SLR cameras, equipped with professional lenses, are not light in weight, and in order to learn how to hold them evenly and firmly without disturbing you, we must take some skills. Let's introduce them below.

"Noise" is another reason why the photos are not clear. By improving ISO-, the digital noise level in photos can be improved, thus reducing the clarity and clarity of photos.

We sorted out the main problems of unclear photos. Now, consider how to avoid this situation, and finally learn how to take clear photos:

First, hold the camera correctly. This may be the main rule for beginners. The result of camera shake is a large number of low-quality images, showing clear and blurred pictures, which is caused by the camera being wrongly fixed in the photographer's hand. How to hold the camera correctly;

Use both hands: grab the camera handle with the right hand and support the lens with the left hand.

Please keep the camera as close to your body as possible: keep the camera as close to your face as possible and press your hand on your body as much as possible to ensure good stability.

Look for supports, such as some walls, chairs, tables, trees, columns, etc. If there is nothing nearby, if you sit and take pictures, please put your elbow on your knee to ensure that the camera is in a stable position in your hand.

Important photos try to hold your breath. When you shoot at a slow shutter speed, it will minimize camera shake.

Second, the tripod tripod is used to reduce or even completely eliminate camera shake. Of course, sometimes they are not practical enough, but with them, you will only get clear photos 90% of the time.

Why only use 90% instead of 100%? Sometimes, even if a tripod is used, it may be blurred because the camera is too big, and the camera will shake the tripod when the shutter is opened/closed, thus causing confusion. When the tripod is not firmly installed on the ground, there will also be installation errors. In short, when shooting with a tripod, you need to accumulate experience, so that the number of successful shooting can reach 100% of the result.

In addition, because the tripod has a long focal length, it is very necessary to shoot from a very long-distance telephone.

Third, the shutter speed If you want to take a clear photo, this may be the first consideration. Obviously, the shorter the shutter speed, the higher the definition of the subject in the picture.

Because the shutter speed is slow, the moving objects in the picture are fixed, which eliminates the possibility of camera shake (even if the camera shake is small, the shorter shutter speed will make up for it).

Depending on the lens and focal length you use, please remember how to set the shutter speed:

If shooting with a focal length of 50mm, do not use a shutter speed lower than 1/60s.

If shooting with a focal length of 100mm, do not use a shutter speed lower than1125 s.

If shooting with a focal length of 200mm, please do not use a shutter speed lower than 1/250s.

In addition, please don't forget the basic law of exposure-the shorter the shutter speed, the more apertures are opened.

Fourth, the aperture aperture will affect the depth of field. Open aperture provides low definition (in other words, the background is blurred), while closed aperture (for example, f/20) increases the depth of field, so that all objects in the frame are sharp and sharp.

So, if you want to get a clear picture, please don't shoot with the maximum aperture. For example, if you take a lens, you can take an aperture chart equal to 1.4, and try to get close to the value of1.8,2.2, and you will see that these pictures are very sharp.

Each lens has a so-called "ideal sharpness point", that is, under a certain focal length and aperture value, the image will be as clear as possible. How to find such a view? Just try to set it up, film it, gain experience, and then you will find it yourself.

5. Sensitivity (ISO) The third element of sensitivity is sensitivity, which directly affects the digital noise of photos. You must remember one thing-the higher the -ISO value, the more digital noise there is in the photo, which means that the clarity and sharpness of the photo will be reduced, because noise destroys the clarity of the image.

As shown in practice, according to SLR cameras, the most acceptable ISO value range is 100 to 800. If it is higher, it means that there is more digital noise in the photo, and the picture must be processed in the photo editor in the future.

Generally speaking, the whole shooting technology includes how to deal with the shutter speed, aperture and sensitivity. If we can find the best values of these three indicators in a given situation, we will always get a clear picture.

Conclusion The above are the basic rules that must be mastered to obtain clear photos. But don't forget the lighting-the stronger the light around you, the clearer the photos you get. For example, even if there is no cloudy day, even if it is cloudy, the photos on the street will be much better than indoors.

Of course, you need to pay attention to many other details, such as: the image is stable (please make sure to turn it on, if the lens or SLR camera itself has this function), please always focus the camera correctly, don't worry, aim clearly. Even if you use autofocus, you should focus on the subject so that it is always clear.

Similarly, the cleanliness of lenses is particularly important.
