What is a 135 film camera like?

The 135 camera refers to the camera that uses 35mm film, which is the kind of film that is packed in a cylindrical metal cassette with holes on both sides, and the most common kind on the market.

The b-door is the hand pressed on the shutter, and the shutter remains open until the hand is released, which is generally used to shoot night scenes.

The focal length of the lens determines the angle of view, and around 50 mm is the same angle of view as a standard lens and the human eye sees things. Smaller than 50 is the wide angle, which can bring more things into the field of view, and larger than 50 is the telephoto, like a telescope.

The film format size of the 135 camera is 36 mm wide x 24 mm high, and the total height of the square perforations is 35 mm.

This film originated from film film at the end of the 19th century, and around 1924 the Germans used it for Leica cameras and formed industrial production, which is the original camera that used 35mm film. Later, it was accepted that 35mm film was called 135 film, and cameras with 135 film were called 135 cameras.

The bulb is to manually control the ** time, that is, to control the opening and closing of the shutter according to your own needs.

How many mm on the lens is to say focal length, focal length, is an important parameter of the optical lens, a photographic lens, also like a convex lens, there are standard, long, short focal length. The length of the focal length = the diagonal of the imaging frame is called the standard lens, the diagonal of the 135 camera is 58mm, the standard lens of the 135 camera is 58mm, the long focal length lens is called the standard lens, and the short focal length lens is called the short focal length lens.

The 135 uses 35mm film, which is the most common one on the market.

The bulb is the shutter time is infinitely long, and the shutter can be opened for as long as you want.

mm is the focal length of the lens.

With cameras with 24x36mm film, 24x36mm is the most commonly used film.

Bulb is only available on SLR, you can completely manually control the time, press the shutter shutter curtain to open, and then press the shutter shutter curtain to close, **time = the time interval between two shutters, mostly used for ultra-long time ** (**time beyond the camera's internal electronic control range, the general internal control range is up to 30 seconds).

The number of mm of the lens refers to the focal length, the larger the number of mm, the longer the focal length, the telephoto can shoot far away, which is equivalent to a telescope, and the short focus shoots a wide angle, which is mostly used to shoot landscapes.

1. Cameras that use 120 film are collectively referred to as 120 cameras.

The 120 camera usually refers to the medium-format camera, the size of the medium-format film is the middle of the 135 and 4 x 5 films, so it is called the medium-format camera, and the 120 camera is named because of the use of 120 film. "120"Originally the number of Kodak film in the United States, the film was used by various countries, and when this number was adopted in the later formulation of international standards, this number was officially recognized by all countries.

Second, the difference between the 120 camera and the 135 camera.

1. Film width.

The 135 camera uses a film with an effective shooting width of 24mm, while the 120 camera has an effective film shooting width of 60mm.

2. The size of the negative.

The negative of the 120 is larger, the height of the negative size of the 120 is 6cm, and the length varies according to the back), which is much larger than the 24x36 of the 135.

3. Lens focal length.

Let's take a 6 x 6 as an example: the standard mirror for a 120 camera is 80mm, which is equal to 50mm for a 135 camera, and the 50mm for a 6 x 6 is equivalent to 28mm for a 135 camera.

4. The number of films.

135 film is generally a roll of 36 sheets, 120 is divided into 10 equal frames due to the different backs of the machine, so 120 film can be used in the front room to destroy 9 12 shots**.

A 135 camera refers to a camera that uses 135 film. The film format of the 135 camera is 36 times 24 mm wide, and the total height of the square perforations up and down is 35 mm, so it is also called a 35 mm camera;

The reasons are as follows: 1. Due to the influence of the Leica camera, the 135 film camera quickly became popular;

2. In the future, all cameras that use 135 film are collectively referred to as 135 cameras;

3、 "135"Originally the number of the American Kodak film, the sail section film was used by various countries, and when the international standards were later formulated to adopt this sedan number, this number was officially recognized by all countries, and China adopted the usual international name, and was popularized among the masses.

Nikon was founded in 1917 to produce military optical instruments, and in 1948 it began to produce civilian cameras, which were imitations of the Nikon I camera of Contex in Germany. Nikon's 1954 135 rangefinder camera S2 was the best-seller. Nikon's 1959 135 DSLR camera Big F was sought after by professional photographers.

The 135 is not a model of the camera, the 135 camera is named because of the film;

The slag used in the 135 phase retarder is 135 film, which is 35 mm film.

It depends on whether you want to buy digital or film, Digital 135.

It is equivalent to the current FX format camera; That is to say, the full-frame camera, because the size of the silver beam mold sensor is equal to the size of 35 mm film, so it is called a full-frame camera.

The 135 SLR is a full-frame single-lens reflex camera in FX format.

The more mainstream Canon5D2 1D1D3 Nikon D700 D3 D3S D3X Sony Alpha 900 are now more mainstream on the market.

Simply put, a movie of any resolution. A straight line is drawn on the paper and enlarged to remain a straight line and does not appear grainy.

Theoretically, divided by the atomic diameter of the photosensitive material, this is a very large value as the size of the film resolution of the film.

Therefore, the clarity of the film is only dependent on the accuracy of the lens and the technology after washing.

Film Scan Resolution: The resolution of the scanner.

Size comparison. 135 Sensitive area of film = full-frame digital camera sensor.

135 fingers of the height of the upper and lower ends of the film perforated for 35mm, so the effective height is 24mm, 24mm*36mm of the photosensitive area of the product, a single image of the film.

Another in the same film grayscale, color gradation, color transitions are subtle and natural.

To put it simply, there is no such thing as resolution on film. It's like drawing a straight line on paper, but when you zoom in, it's still a straight line and won't be grainy.

Theoretically, the resolution of a film is the size of the film divided by the atomic diameter of the photosensitive material, which is a very large number.

Therefore, the sharpness of the film depends only on the accuracy of the lens and the technique of post-processing.

If the film is scanned, the resolution = scanner resolution.

The dimensions are comparable. 135 Photosensitive area of film = photosensitive components of full-frame digital camera.

135 refers to the height of the film is 35mm, because there are perforations at the upper and lower ends, so the effective height is 24mm, and the photosensitive area of a single image of this film is 24mm*36mm.

In addition, the film does not have grayscale or color levels, and its color transitions are extremely delicate and natural.

Color film is a three-layer dyeing emulsion, each of which feels a different color light, and its emulsion particle size is similar to the pixels of a digital camera.

The higher the ISO value, the larger the emulsion particles. Taking ISO100 film as an example, converting the emulsion particles of 135 film into pixels is about 10 million to 14 million (the process level of each factory is different, and the particle size is also different).

The resolution of 135 film is about 10 million pixels, and 120 film can reach about 50 million pixels. The granularity of the film is closely related to the quality of the film and the processing process, so it is not possible to scale up indefinitely.

At present, the world's top CCD has reached 100 million pixels, which is completely comparable to 120 film, so it has been used in aerospace fields such as astronomical research.

Simply put, any resolution of this film. A straight line is drawn on paper, and the enlargement is still a straight line, and it does not appear grainy.

Theoretically, the size is divided by the atomic diameter of the photosensitive material, which is a very large value as the resolution of the film.

Therefore, the clarity of the membrane depends only on the accuracy of the lens and post-wash technology.

Negative scanning, resolution of the scanner's resolution.

Size comparison. 135 Film's photosensitive area = full-size digital camera sensor.

135 refers to the sensitive area of the image of this film single due to the upper and lower ends of the film perforation with a height of 35mm, so the effective height is 24mm, and the product of 24mm * 36mm is single.

The other is the same, the cinematic grayscale, the color gradation, the color transition is a subtle and natural.

Hello. What are the advantages and disadvantages of the 135 SLR camera The advantages and disadvantages are as follows: 1,135 The camera is small in size, light in weight, and easy to carry.

The lens has a large effective aperture, strong adaptability to different lights, and can shoot when the light is dark and the flash cannot or is not allowed to be used, and can record the unique atmosphere and effect of air shooting in the early natural light, and has a high-speed shutter, which can meet the needs of shooting high-speed moving objects. The downside is that with a curtain will limit flash sync, and you can't achieve very high shutter speeds when using flash. 2 When the sensitivity of a digital camera is high, particles can also appear in the image.

The factors that affect the imaging of the image sensor of the digital camera are the area of the sensor and the color depth of the sensor.
