What are the three types of photographic lenses, and what kind of images are suitable for shooting?

There are three types?? 、

From the focal length, it is divided into wide-angle, medium-focus, and telephoto lenses, I don't know if you are talking about this division.

Wide-angle is generally used to shoot large scenes such as scenery, venues, and buildings. Within 28mm is called a wide angle.

Medium focus: used to shoot portraits, humanities, and landscapes suitable for this focal length. In fact, the purpose is the same, but the focal length is different. Generally, it refers to 28-105 focal lengths, which are not clearly divided.

Telephoto, suitable for shooting long shots, wildlife, birds, concerts, and street shots. Generally refers to 100-400mm, and it is also said that more than 200mm is super telephoto.

There are also functional divisions, such as wide-angle heads, portrait heads, macro heads, and different divisions.

Portrait heads mostly refer to large-aperture lenses between 35-135mm.

A macro head, a close-up shot of small things.

That's about it.

I don't know what you're talking about

The lens can be divided into prime focus and zoom, and the prime head imaging ***** cheap, but it is inconvenient to use The zoom head is easy to use, but the imaging is very expensive

According to the function, the lens can be divided into wide angle and telephoto

The wide angle is to shoot a large scene, and the telephoto is to zoom in on the distant thing

If you take a silhouette, you will generally shoot against the light, and if you measure the bright light behind the photometering, the person will become a silhouette

Let's use the focal length.

The wide-angle focal length results in a wide field of view.

Magnificent, great depth of field.

It is suitable for shooting large scenes and large perspective effects.

The field of view obtained by the mid-focus focal length is relatively small, and it is similar to the perspective of the human eye, which is suitable for shooting people and still lifes.

The telephoto focal length has the smallest field of view and a small depth of field, which is relatively suitable for telephoto shooting, and can also shoot landscapes, and will get a good depth of field effect when shooting people. Photography enthusiasts call the 18 200mm lens "one shot" because it covers all focal lengths from wide angle to telephoto, making it ideal for travel photography and saving maximum space in your backpack.

Panorama, Medium Panorama, Medium Close-up, Medium Close-up, Close-up, Wide Close-up, Full Close-up, Medium Close-up, Very Close Up.

1. Panoramic lens, also known as full-body lens, refers to the whole person appearing in the picture from head to toe, panoramic lens is generally used for two-person or multi-person pictures, due to the shrinking of the characters, the background behind them is clearer and more comprehensive, which can provide more background information to the audience and make the picture look more vivid.

2. Medium panorama refers to the part from the top of the head to the knees that appears in the picture.

3. The middle shot is from the top of the head to the part below the waistband, and as the camera gradually zooms in, the emotions of the characters will gradually amplify.

4. Medium and close-up scenes refer to only the top of the head to the waist in the picture, when the hands and feet are cut off outside the picture, the actor's performance must rely on facial expressions to show his performance, if it can not match the corresponding body movements, and there is no rich facial expression, then the camera can only convey a sluggish and rigid performance.

5. Only showing the chest above the chest in the picture is called a close-up, from the close-up scene, the actor must pay attention to the amplitude of the action, too much movement will run out of the picture, so the performance in front of the camera must find an accurate position, within the specified space to play their acting talents.

6. Only two shoulders are exposed, and the picture cut from the neckline is called a wide close-up, and the lens above the close-up is not often used in movies, but will appear frequently in TV dramas, because the size of the TV screen will not make people look exaggerated;

The oversized close-up in the movie screen will only give people a strong visual impact, unless there is a special performance, there will not be too many close-ups in the general film shooting.

7. Cutting up from the neck up is called a full close-up.

8. Only the head is called a medium close-up, as the camera closes in, other disturbances such as the background will be ignored, and the audience can only see the delicate performance of the actors, and they can also feel the complex inner and emotional changes of the characters.

9. The picture with only the eyes in the whole picture is called a very close close-up, which is often called a local close-up;

Of course, the local close-up is not necessarily just the eyes, but may also be other parts of the body.

Lenses are mainly divided into four categories: fixed focus, zoom, macro and tilt shift, which are subdivided according to focal length: fixed focal length lenses include wide-angle fixed focus (less than 35mm), standard fixed focus (50mm), medium telephoto fixed focus (85 to 100mm), telephoto fixed focus (100 to 300mm), super telephoto fixed focus (greater than 300mm), strictly speaking, macro and tilt shift are actually fixed focus lenses, but the use is more special, and the structure is somewhat different.

The lens has two fingers in film and television, one refers to the optical components used by the movie camera and projector to generate the image, and the other refers to a continuous picture shot from the start to the shutdown, or the clip between two editing points, which is also called a lens. One finger and two fingers are two completely different concepts, in order to distinguish the difference between the two, one finger is often referred to as an optical lens, and the other is referred to as a lens picture. According to the origin of the lens, it is mainly classified as Japanese lenses and German lenses.

The Japanese lens mainly has a better color reproduction, and the German lens has a strong sense of hierarchy. Chinese lenses in the market are also gradually occupying a certain market, mainly because they are relatively cheap.

What are the effects of different lenses and different focal lengths on taking portrait photos?

The division of scenery can generally be divided into five types, from near to far.

Close-up (refers to the human body above the shoulder). Close-up prompts information, creates suspense, can subtly express the facial expressions of the characters, portray the characters, and express complex character relationships, which has a special visual experience that is not common in life.

Close-up (above the human chest). The close-up focuses on the facial expressions of the characters and conveys the inner world of the characters. It is the most powerful scene to portray the character of the character.

Medium view (above the knee). The medium scene is the most powerful kind of scene. In scenes that involve dialogue, action, and emotional exchange, the use of medium scenes can be the most beneficial and balanced way to express the relationship between the characters and the surrounding environment.

Panorama (the whole body and the surrounding background). Panorama is used to show the whole picture of the scene and the whole body movements of the characters, and is used in TV dramas to show the relationship between the characters, people and the environment.

Distant view (the subject's environment). The long shot is generally used to show the whole environment away from the camera, showing the people and the vast space environment around them, natural scenery and large-scale scenes of mass activities.

In the film, the director and the cinematographer use complex and changeable scene scheduling and lens scheduling, and alternately use a variety of different scenes, which can make the narrative of the film's plot, the expression of the characters' thoughts and feelings, and the handling of the relationship between the characters more expressive, thereby enhancing the artistic appeal of the film.
