What types of cameras are there?

Abstract: The principles of cameras are the same, but according to the differences in components and structural arrangements, they can be divided into disposable cameras, 35mm automatic cameras, 35mm direct viewfinder cameras, etc. Each of these cameras Each has its own characteristics, advantages and disadvantages. For example, although a 35mm automatic camera is easy to operate, it leaves little room for creative photography. Let’s take a closer look at the classification of cameras and their characteristics! 1. How to classify cameras

Although all cameras include some basically the same parts, the differences in the arrangement of these parts and structure result in different types of cameras. Different cameras have different features and advantages. It is worth mentioning that the cameras mentioned below now have corresponding digital versions. Except for different photosensitive devices, they all maintain their original advantages and usage characteristics, and are used in Each field gradually plays an increasingly important role.

2. Types and characteristics of cameras

1: Disposable camera: At present, the simplest camera is the disposable plastic camera produced by the American Kodak Company and the Japanese Tomei Company. . This is equivalent to today's "Brownie" box camera, which has no device to control exposure and focus. Of course, it really doesn't work for the kind of high-quality photography one would expect. That kind of work requires a camera that can provide comprehensive and careful planning and control of the shooting; perhaps the following types of cameras will do the trick.

2: 35mm automatic camera: This camera is designed to compete for the market of amateur photographers. It is called a "point-and-shoot camera" because of its simple operation. They use computer chips to complete everything as automatically as possible: automatically "read" the film's photospeed from the mark on the film cassette, automatically calculate the exposure, automatically focus the image, and automatically roll the film to the next frame after shooting. However, while enjoying all these great features, you have to endure the following three major limitations:

1) This camera does not allow changing lenses, although many of them may be equipped with zoom lenses. its own characteristics.

2) This kind of camera focuses through a glass viewfinder, and it often cannot display exactly the same image as recorded on film.

3) Such cameras offer little or no manual control over focus or exposure. They leave little room for creative control of the image.

3: 35mm direct viewfinder camera: This is the earliest style of 35mm camera. It is almost identical to the early Leica camera prototype designed in 1913. Similar to the 35mm automatic camera introduced earlier, the direct view camera also focuses through the viewfinder window. It often cannot display the exact same image as recorded on the film (this is the difference between it and a single-lens reflex camera. Later, (or the image in the viewfinder will be exactly the same as the image recorded on the film). However, unlike the 35mm automatic cameras mentioned above, direct-view cameras allow for interchangeable lenses and provide maximum creative control over focus and exposure. Although this type of camera has now been largely replaced by single-lens reflex cameras, it is still favored by some professionals for some reason.

4: 35mm single-lens reflex camera: This is a device widely used by serious photographers today. Observing and focusing images directly through the lens are its important features. Some single-lens reflex cameras are fully manual, meaning the photographer must turn dials and dials to focus the image and set the exposure; others are almost fully automatic. This type of single-lens reflex automatic camera solves the problems involved with the simple 35mm camera previously described:

1) The lens can be changed, allowing the appropriate lens to be selected for each job.

2) You can view the exact same image as recorded on the film, allowing precise adjustments to the image.

3) There is also often the option of automatically controlling compensation, allowing creative appearance characteristics to be determined for each frame.

5: inch SLR camera: It is similar to a 35mm SLR camera, but this larger SLR camera usually uses 120 roll film and produces inch-wide film. Hasselblad (Hasselblad, the trade name of a 120-degree single-lens reflex camera.) camera was once taken to the moon for use by American astronauts.

6: Twin-lens reflex camera: This kind of camera has two lenses, the upper lens is used for framing and focusing, and the lower lens is used for shooting. The film used is usually 120 rolls, and is produced accordingly. During the 1930s and 1940s, Rollei was favored by many professionals.

7: One-step imaging camera: This camera produced by the Polaroid Company has completely revolutionized the photography enthusiast market that has lagged behind for decades. This technology produces film-based black and white or color "instant" photos. Unfortunately, basic one-step imaging cameras don't offer satisfactory imaging control for really serious work. For professionals, the most common use of a one-step camera is to take "test" photos of lighting effects in the studio (now that more advanced tools are available).

8: Back view camera: usually used for photo studio (or photography studio) photography, or large and complex industrial and architectural location shooting. Back view cameras, like the Xinar F4×5, mostly use 4-inch by 5-inch, 5-inch by 7-inch, or 8-inch by 10-inch loose-leaf film and are designed to be mounted on a tripod.
