Novice, Nikon D8 10, the clear shooting range is horizontal, what's the problem? How can I set it to make the clear range bigger? Problems and uses of lenses, such as
This is because the depth of field is too shallow when shooting.
The so-called depth of field refers to the range before and after the lens can clearly image with the focus as the center. ..... In some conditions, the depth of field is very shallow, so only part of the photos are clear, and most of the rest are blurred ... In other conditions, the depth of field is wide and most of the scenery is clear.
Specifically, the factors that affect the depth of field during shooting are as follows:
1, aperture size has a great influence on depth of field.
When shooting with a large aperture, the depth of field will be very shallow, only a small part of the scenery around the focus is clear, and the rest are blurred.
When we take portraits, we generally like to blur the background, that is, shoot with a large aperture.
We shoot with a small aperture, the depth of field is very wide, and the far and near scenery will be very clear. ..... We are looking for a clear picture when taking a landscape photo, so we will choose a small aperture when taking a landscape photo.
2. The focal length also has a great influence on the depth of field.
Under the same aperture, the focal length will have a great influence on the depth of field.
The shorter the focal length, the wider the range of depth of field. ..... so it's hard to blur the background when shooting with a wide-angle lens.
The longer the focal length, the narrower the depth of field, and the more obvious the foreground blur and background blur effects will be. ..... so it is easy for us to take a blurred background with a telephoto lens.
3. The focal length will also have a great influence on the depth of field.
In addition to focal length and aperture, focal length also affects depth of field.
The closer the focal length, the narrower the depth of field, and the more obvious the foreground blur and background blur effects will be.
The farther the focusing distance is, the wider the range of depth of field is ... When focusing at infinity, basically the scenery everywhere will be very clear.
Therefore, the reason why most scenes in your photos are blurred is because the aperture is relatively large and the focal length is relatively close. ..... set a small aperture and reduce the focal length, which can make the clear range of the shooting picture wider.
As for the focal length ... the lens you use is a 105mm lens ... the focal length is fixed ... but this lens is a macro lens, and the depth of field will be very shallow when shooting at close range, so you need to shoot with a smaller aperture, or even stack it to get a clear lens. ..... If you want to master the above shooting methods skillfully, you need to sum up and accumulate for a long time. As long as I step by step, I can master the relevant shooting skills and shoot my own satisfactory photography.
