What does wide angle mean?

Question 1: What does "wide angle" mean in photography? Wide-angle lens is a photographic lens with shorter focal length, larger viewing angle, longer focal length and smaller viewing angle than standard lens.

Wide-angle digital camera has short focal length, wide viewing angle and deep scenery, which is suitable for taking photos of large scenes, such as architecture and scenery.

Wide-angle lens is widely used to shoot large-scale landscape photography. Can increase the sense of spatial depth of the photo picture; The depth of field is long, which can ensure that the scene before and after the subject can be clearly reproduced on the screen. Therefore, the vast majority of modern pocket automatic cameras (commonly known as fool cameras) use ordinary wide-angle lenses of 38-35 mm; The lens covers a large area and shoots a wide range of scenery; The scene shot at the same shooting distance is smaller than the scene image shot with standard lens in the picture; The defects of perspective distortion and image distortion are easy to appear in the picture. The shorter the focal length of the lens and the closer the shooting distance, the more obvious this defect is.

wide-angle lens

For most popular digital cameras on the market, the wide-angle focal length is generally between 35 and 38 mm. The real wide-angle digital camera is actually a product with a lens focal length covering a wide angle of 28 mm

Question 2: What does a wide-angle lens mean? Wide-angle lens is a photographic lens with shorter focal length, larger viewing angle, longer distance and smaller viewing angle than standard lens. Lenses are divided into ordinary wide-angle lenses and ultra-wide-angle lenses. 135 camera's common wide-angle lens has a focal length of 38-24 mm and a viewing angle of 60-84 degrees. The ultra wide-angle lens has a focal length of 20- 13mm and a viewing angle of 94- 1 18 degrees. Because the wide-angle lens has a short focal length and a large viewing angle, it can shoot a large area of scenery in a short shooting distance. Therefore, it is widely used to shoot large-scale landscape photography. In photography creation, using wide-angle lens to shoot can achieve the following effects: first, it can increase the sense of spatial depth of photographic images; Second, the depth of field is longer than the normal distance, which can ensure that the scene before and after the subject can be clearly reproduced on the screen. Therefore, the vast majority of modern pocket automatic cameras (commonly known as fool cameras) use ordinary wide-angle lenses of 38-35 mm; Third, the lens covers a large area and shoots a wide range of scenery; Fourthly, the scene shot at the same shooting distance is smaller than the scene image shot with the standard lens; Fifth, perspective distortion and image distortion are easy to appear in the picture. The shorter the focal length of the lens and the closer the shooting distance, the more obvious this defect is. Therefore, when shooting portraits, it should not be close to 0.6 meters to avoid perspective distortion. If you use ordinary wide-angle lens to shoot standard portraits for pasting files, it is best to shoot them in waist-length or knee-length images; When taking this portrait photo with super wide-angle lens, it is best to take a full-body portrait, and then cut it in the process of enlargement to get a standard portrait photo with wide-angle effect to avoid perspective distortion. Of course, sometimes we can consciously use this perspective distortion to alleviate some defects of the subject's face when shooting portraits. If the subject has a narrow forehead and a wide chin, he can shoot with a slightly higher overlooking angle to offset the defects; On the other hand, low-angle upward photography can be used. When shooting a full-length portrait with a wide-angle lens, there will still be distortion if shooting at a low angle, but sometimes this feature can be used to make up for some shortcomings of the subject. For example, some subjects' legs are shorter than their body length, and shooting at this angle will make their legs appear slender on the screen and increase the aesthetic feeling. Shooting with a wide-angle lens will not only produce perspective distortion, but also produce edge distortion. This distortion is mainly caused by the oblique projection angle from the back of the lens to the edge of the film field of view. When shooting a group image, it is easy to make the subject on the edge of the picture short and fat.

Question 3: What does the wide angle of the camera lens mean? Wide-angle lens can produce the effect of big prospect and small prospect. The image distortion produced by wide-angle lens exaggerates the foreground object, highlights the foreground object more, and gives people a strong visual impact. For friends who like to travel, the benefits of wide-angle lens are obvious. It can shoot a wider landscape and is more suitable for showing the beauty of the landscape. The real wide-angle digital camera should be a product with a wide-angle focal length below 28 mm The larger this value, the more obvious the wide-angle lens is. Because of its short focal length and large viewing angle, it can shoot a larger area of scenery in a shorter shooting distance.

Question 4: What does a wide-angle display mean? The monitor has two polarizers to display the picture and an angle. When you look at the monitor from some angles, it will appear that the color is white, but the wide-angle monitor will not.

Question 5: What do you mean by wide angle and aperture? Wide angle refers to the field of view of the lens, which can obtain a wider field of view than the standard lens and telephoto lens. Because it has a larger angle of view, just like the scenery seen by fish eyes, it is also called fisheye lens.

Aperture is about the amount of light entering and depth of field, and the size of aperture represents the range of light entering and depth of field. Aperture and shutter speed can get the exposure people need; By controlling the aperture size, the required depth of field can also be obtained.

Question 6: What is a wide-angle lens and what is a wide-angle lens?

The so-called wide-angle lens is a lens with short focal length and large viewing angle. The purpose of using a wide-angle lens is to obtain a wider field of vision and magnificent artistic effects. Wide-angle lens can produce large foreground and small foreground effects. The picture distortion produced by wide-angle lens exaggerates the foreground object, highlights the foreground object more, and gives people a strong visual impact. For consumer digital cameras, the so-called wide angle is actually 28 mm

To put it bluntly, the general camera can only see the area in front of you, while the photos of wide-angle cameras can let you see more and more pictures that can't be displayed at wide angles. The wider the wide angle, the closer it is to people's actual field of vision, and the more comfortable the photo looks, especially when shooting landscapes and other pictures.

What's the use of wide angle:

For tourism, the benefits of wide-angle lens are obvious. It can shoot a wider landscape and is very suitable for showing the beauty of the landscape.

Wide-angle lens is used to enclose a large photographic area, which is wider than the area without wide-angle lens and shoots more scenes than before.

The meaning of extending from focal length to wide angle;

According to the principle of photography, the smaller the focal length, the wider the field of vision, and the wider the range of scenery that a photo can accommodate. The shorter the focal length of the lens, the greater the deformation of the scene, but the perspective effect is good, which can better represent the depth of the picture and obtain a wide range of clarity, that is, the depth of field is greater. Some digital cameras make use of the feature that the scene can be clearly imaged after a certain distance with a short-focus lens (hyperfocal distance), which saves the focusing function, reduces the product cost and is also beneficial to snapshot.

For most popular digital cameras on the market, the wide-angle focal length is generally between 35 and 38mm. The real wide-angle digital camera is actually a product with a lens focal length covering a wide angle of 28mm. Because the wide-angle field of view of 28 mm is wider than that of 35mm and 38 mm commonly used in digital cameras, the wide-angle field of view of 28 mm is 76 degrees, while that of 35mm is only 62 degrees, so it can produce very unique visual effects and accommodate a wider scene. This is also the reason why consumers are more optimistic about 28mm wide-angle digital cameras. The biggest feature of wide angle is that it can shoot a wide range, with exaggerated sense of distance and wide focus range. When using wide angle, you can enlarge the object in front of you and narrow the object in the distance, and the surrounding images are easily distorted. Wide-angle can also adjust any point in the image to the most appropriate focal length to make the picture clearer, which can also be called complete autofocus.

Question 7: What do you mean by wide angle and telephoto? Wide-angle lens is a kind of short focal length lens, which can shoot a wide scene in a short distance. If you want to take a wide subject and make the image bigger (to widen the distance from the subject, the photo can indeed contain a wide theme, but the image is smaller), you can use a wide-angle lens. It is often used in portrait photography.

As the name implies, a telephoto lens is a lens with a long focal length. When the subject is far away, it can be used to close the distance between the subject and the camera, so it is also called telescope head.

Question 8: What does the wide-angle lens of SLR mean? What about wide angle? Is it the closest focal length? A 50 mm lens is called a standard lens. The viewing angle is generally around 44. Wide-angle Sichuan projection generally refers to a lens smaller than 50 mm, not the closest focal length. Is the biggest perspective. For example, 10.5mm in dx and 16mm in fx are both 180 degrees.

Question 9: What does the wide angle of a digital camera mean? Wide-angle lens can produce large foreground and small foreground effects.

The picture distortion produced by wide-angle lens exaggerates the foreground objects.

More prominent foreground objects, giving a strong visual impact.

For friends who like to travel, the benefits of wide-angle lens are obvious, which can shoot a wider landscape and show the beauty of the landscape more appropriately.

For most popular digital cameras on the market, the wide-angle focal length is generally between 35 and 38 mm.

The real wide-angle digital camera should be a product with a wide-angle focal length below 28 mm The larger this value, the more obvious the wide angle is.

Because the wide-angle lens has a short focal length and a large viewing angle, it can shoot a large area of scenery in a short shooting distance.
