An Analysis of Film Focus
1. ** Standard focal length (35 - 50mm)** - Its effect was the closest to the human eye. When using 35mm film as the standard, the focal point distance of the lens within this focal length range made the image closer to reality and reduced the distortion caused by perspective. It was often used in conventional and realistic movies. 2. ** Short focal length lens (less than 35mm)** - ** Field of view **: It has a wide field of view and is open. For example, a wide-angle lens between 16 - 35mm can shoot large-scale scenes at a short distance. It can show more information when shooting scenery and grand scenes. For example, epic films and war films often use it to shoot grand scenes to express their emotions. - ** Depth-of-field **: With a large depth of field, it can clearly display the contents of the front, middle and back scenes. It conforms to the characteristics of the depth-of-field lens. The audience can freely choose the content to watch and reflect the realism. For example, in the scene of Citizen Kane, different characters were clearly visible. - ** Spatial sense **: It will increase the sense of space vertically and widen the distance between objects. For example, Citizen Kane used it to emphasize the physical and psychological distance between characters. - ** Distortion effect **: It has the effect of distortion and distortion. It should be used with caution when taking group photos. However, it can be used to adjust the body proportion when shooting people. Extreme ones such as fisheye lenses (short focal angle close to or more than 180°) have obvious distortion effects. They are humorous and have a cartoon feel. They can magnify the subject to bring visual stimulation, such as the tunnel lens in Fallen Angel. 3. ** Telephoto lens (narrow field of view)** - It could cross the front, highlight the middle, and zoom-in the distance. It could take a larger image of a distant object, which had the effect of zooming in the main body and compressing space. For example, the 100mm focal length lens could draw closer to the characters, allowing the audience to pay more attention to the expressions of the actors. However, too long a focal length would make the depth of field small, making it difficult to shoot at close range, and it might make the face not three-dimensional. At the same time, the telephoto lens could compress the distance between objects to increase the sense of pressure. When moving with the object, it would increase the sense of movement speed due to the change in the background and background. 4. ** Movie lens and camera lens comparison and characteristics ** - "In terms of stability and focus, the movie lens is more stable than the camera lens, and the focus is more accurate and standardized. Movie lenses had a long focus range, usually more than 270 degrees. The focus ring and aperture ring had a snap to facilitate the installation of a focus tracker. This was to meet the focus requirements of film shooting (there were specialized focus tracker positions). - ** Appearance and series **: From the outside, the movie shots are released according to the series. Even if the focal lengths of the entire series are different, the length and weight of the shots are the same, so there is no need to readjust the stabiliser balance during shooting. - ** Aperture expression **: Movie lenses use the T value to represent the aperture (the actual amount of light), while camera lenses often use the F aperture (assuming that 100% of the light passes through the lens, but there is actually a loss of light). - ** Breathing effect **: The film lens is good at controlling the breathing effect (the slight change in focal length when the lens changes focus). Modern fixed-focus film lenses generally use double floating lens group focusing to solve the breathing effect problem on the basis of maintaining the aberrations correction balance. Moreover, the film shots were generally stylized (related to coating). Read more exciting novels for free
Film Focus
Focus was a very important part of filming. The following are some key points related to film focus: ** 1. The effect of the lens focusing motor on the focus of the movie shooting ** 1. ** Stepping motor (ATM)** - The working principle was to drive the stepping motor through an electrical signal to rotate it step by step within a specific angle, thereby achieving precise control of the internal focus group of the lens. - In film shooting (video shooting), it was featured by smooth focus and low noise. It could accurately control the focus point when fine-tuning the focus. It was suitable for static film shooting scenes in quiet environments. 2. ** Horizontal motor ** - Its working principle was to directly drive the focusing mechanism to move in a straight line through electromagnetic force. - In film shooting, it was featured by fast focusing speed and high focusing accuracy. It was suitable for dynamic scenes that required fast focusing in film shooting. ** 2. Other factors that affect the focusing speed of a movie lens ** 1. ** Light ** - The art of photography was the art of using light. Whether there was enough light during shooting was an important factor that affected the speed of focusing. In a movie, the weaker the light, the slower the focusing speed. 2. ** Number and distribution of focal points ** - The more focal points there were, the wider the distribution. The focusing system could lock onto the target more flexibly and quickly, which was especially important in the complex scenes of a movie. 3. ** Focus ** - The length of the focal length also affected the focusing speed. In film shooting, the longer the focal length, the slower the focusing speed. Especially at long distances and large apertures, the focusing system needed more precise adjustments. 4. ** Anti shake system ** - In low-light environments, the anti-shake system could reduce hand shake, which helped the focusing system lock the focus faster and more accurately, improving the focusing speed. However, when using a tripod to shoot steadily, the anti-shake system may increase the time the camera takes to process data, especially when the anti-shake function is activated, which will reduce the focusing speed of the lens. ** 3. Focus characteristics of different types of movie lenses ** 1. ** The difference between an AF-lens (autofocus lens) and a manual focus lens in movie shooting ** - In terms of optical structure, there was no essential difference between the AF-lens and the manual focusing lens, but the mechanical structure was different. The basic point of the design of the AFF lens was the transmission path of the autofocus power. - The AF-lens had electronic contacts that were used to exchange various parameters with the body, such as the focal length of the lens, the maximum and minimum apertures, the closest focusing distance, etc. The camera set the corresponding working mode according to these parameters. This would help to work better with the filming equipment during filming. - In the actual operation of the movie shooting, the manual focus lens required the photographer to manually adjust the focus, while the AF-lens could automatically adjust the focus according to the shooting needs. 2. ** The characteristics of the body-driven AF-lens in movie shooting ** - The driving source of the body-driven AF-type lens came from the body of the AF-type single-lens reflex camera. There was a transmission mechanism in the lens that was connected to the manual focusing ring. During autofocus, the manual focus ring on the lens was rotating, and because the design took into account the smoothness of the transmission, the mechanical structure of the focus ring might appear a little loose. If you use this type of lens in a movie, you should pay attention to avoid accidentally touching the focus ring during autofocus. 3. ** The characteristics of the lens-driven AF-lens in movie shooting ** - The lens-driven AF-lens body only transmitted focus signals and power to the lens. All mechanical movements were completed within the lens, and there was no mechanical connection between the lens and the body. This kind of lens was relatively independent in the focus operation during movie shooting, and it might have better compatibility and flexibility in some specific combinations of film shooting equipment. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Analysis of the Focus Distance
Focus distance refers to the distance between the object and the image. It is the sum of the distance from the lens to the object and the distance from the lens to the sensor. There were a few related concepts that needed to be understood in photography: 1. [Depth-of-field: When an object is focused, all the objects from a certain distance in front of the object to a certain distance behind the object are also clear. This distance is called depth of field.] The depth of field was divided into the front depth of field and the back depth of field. The back depth of field was greater than the front depth of field. The depth of field was related to the focusing distance. The further the focusing distance, the deeper the depth of field. The closer the focusing distance, the lighter the depth of field. The longer the focal length, the smaller the depth of field. The shorter the focal length, the greater the depth of field. 2. ** Focus **: The focal length is directly proportional to the size of the image. The longer the focal length, the larger the image. The shorter the focal length, the smaller the image. The focal length of the lens is inverse proportional to the angle of view. The longer the focal length, the smaller the angle of view. The shorter the focal length, the larger the angle of view. The focal length is inverse proportional to the strength of the perspective. The longer the focal length, the weaker the perspective. The shorter the focal length, the stronger the perspective. The focal length is inverse proportional to the contrast. The longer the focal length, the smaller the contrast. The shorter the focal length, the greater the contrast. The lens also had the concept of the closest focusing distance, which referred to the straight-line distance between the object focal plane (the object being photographed) and the image focal plane (the image sensor). Focus was also called aiming and focusing. It referred to adjusting the focal distance when using the camera. Usually, digital cameras had autofocus, manual focus, multi-focus, and many other focusing methods. The camera's focusing mechanism changed the distance between the objects and the distance between them, so that the image of the object was clear. The focal distance of the lens was usually expressed in centimeters. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
