Why are the photos you take always burnt? (share)
1. Shutter speed is too slow
The most common reason for unclear photos is camera shake, which blurs the whole image and makes people feel uncomfortable. All this is because the shutter speed is too slow to capture the moment of the image. And in the process of shooting, you think it has been relatively stable, but you don't know that even if you press the shutter gently, it may cause the picture to burn!
So what shutter speed should I use? This obviously depends on your environment and experience, but there is a general rule of thumb that the shutter speed is greater than the focal length of your lens. For example, if you shoot with a 200mm equivalent lens, the shutter speed should not be slower than 1/250 seconds, otherwise your camera shake will destroy your shooting.
2. Rely too much on the stability of the camera
Every camera has its own anti-shake system, which is very useful whether it is built in the camera or in the lens. It allows you to shoot at a slower shutter speed than usual. In some cases, you can get a clear image at a relatively slow speed!
If you shoot a static object, the automatic shift is usually enough to shoot a clear image, but if your subject is moving and the shutter speed is not adjusted properly, the picture will be blurred! To avoid this, please make sure that the shutter speed you use is enough to capture your theme. At this time, you may need to improve the ISO sensitivity of the camera to achieve this goal!
3. The set ISO value is too high
In some cases, you may have to set a very high ISO value to improve the sensitivity of the camera to images, so as to avoid "pasting photos" caused by hand shaking. Of course, the sensor of the camera has been greatly improved in recent years, which also allows everyone to shoot at high ISO values, but the details will be lost more or less. This is especially true when you take photos in JPEG format, because the sensitivity increases and the noise increases, which sacrifices the details of the image.
In order to avoid this situation, you can turn on the original picture saving mode, that is, the RAW format, when shooting, so as to keep the best quality of the picture as much as possible.
4. The aperture is too big or too small
If you are shooting a landscape, in most cases, you will want to shoot a wide-angle and clear image. In this case, you need to use a small aperture, because it can increase the size of the focus area and get a clear image of a large area. But sometimes the picture will be blurred when you drive to a small aperture like F 16 or F22. Why? Because the aperture inside the lens is too small, the light will bend when passing through the edge of the aperture blade, thus preventing the light from focusing on the sensor. Without light, images will naturally be pasted.
To avoid this, the shooting aperture should be slightly larger, for example, to F 1 1.
Or your subject is a small part, and you need to blur the background. At this time, you need to use a large aperture on the lens, such as the aperture value of F2.8, and you may get the desired effect! If this is not what you expect, then you should continue to increase the aperture to get the depth of field, but at this time, you must pay attention to your shutter speed, because the aperture will increase and the shutter will slow down.
5. Put the camera in the wrong place
Poor technique is the chief culprit of many blurred shots. If you don't hold the camera correctly, it will easily lead to camera shake, even if you use a fast shutter speed, it can't be avoided.
The best way is not to use the rear monitor to compose and shoot, but to hold the camera above your eyes and support the weight of the lens with your left hand to form a "triangle". You will get a good and stable foundation, and then you can start shooting! Don't worry without a viewfinder! Although there is no fulcrum for the head to contact the lens, you can still use the above method to form a relatively stable state with your left hand and right hand.
In some cases, you may want to lean against the wall or lie on the ground with your elbows open like a tripod. Speaking of this, in many shooting environments, a tripod is essential, because when the light is very weak, the shutter speed will be much slower than you think. At this time, you can't get stability with your body, you can only rely on a tripod to stabilize and capture wonderful moments.
6. The focus mode is wrong
Most cameras use autofocus area mode as the default autofocus setting, which allows the camera to completely control and decide what it thinks should be focused on. This is probably a misunderstanding of many photographers. It is impossible to rely entirely on the focus of the camera, because its judgment is quite mechanical! Choose a good focus mode when shooting. It is generally recommended to choose the single-point AF focusing mode, which can help you capture what you want accurately.
If you want to shoot a static subject, it is generally a perfect operation for your camera to use the single focus above! But if your subject starts to move, your image will lose focus. Because when you half press the shutter button, the focus is locked, and it will not update the focus.
To make up for this, you need to switch the camera's focus mode to continuous mode, so that when shooting, the camera can constantly update its focus as your subject moves, just like these cyclists in the above shot.
Remember, not all camera focusing systems are the same, and your camera may not be able to keep up with fast moving objects. In addition, if your object moves within a controllable range, you can capture your object by switching the camera focus mode and focus.
7. Try to take a step back
If you want to focus on a place close to you, you may find your photos blurred. This is often due to the limitation of the lens, and it is impossible to be as accurate as the human eye. In most cases, if the lens is too close to the subject, you can't get a clear image.
To solve this problem, maybe you should just take a step or two back when shooting, so that the distance between enlarger lens and the subject can be avoided. If you really want to take a close-up, you can consider buying a macro lens, because these lenses can help you get the image you want.
8. Wipe your lens!
Maybe you avoided the seven points mentioned above, but you still got a blurred photo. Stop doubting yourself. Try to look at the camera and check whether the lens is dirty or has water vapor! Many conditions can cause the lens to be covered with water vapor. For example, if you walk into a humid indoor environment, your lens may be covered with fog, resulting in a blurred and soft focusing effect. If you start from a relatively warm place and then go straight to a cold place, you will experience the same thing, and it is the same.
There are other reasons for the blur, which may be that the lens was accidentally stained with fingerprints. Remember to check before taking pictures!
Get this at eight o'clock, but also afraid to take "paste photos"! Hurry up and pick up your cannon to shoot a massive HD codeless blockbuster!
