Question: Which lens is used in camera straight line to curve line?

Answer: In photography, a rectilinear lens is a photographic lens that yields images where straight features, such as the walls of buildings, appear with straight lines, as opposed to being curved. In other words, it is a lens with little or no barrel or pincushion distortion. At particularly wide angles, however, the rectilinear perspective will cause objects to appear increasingly stretched and enlarged as they near the edge of the frame. These types of lenses are often used to create forced perspective effects.

The most famous example is the Rapid Rectilinear Lens developed by John Henry Dallmeyer in 1866.

Question: what is photography?

Answer: The art or process of producing images by the action of radiant energy and especially light on a sensitive surface (such as film or an optical sensor)

Examples of photography in a Sentence

Studied both film and still photography.

Landscape photography is her hobby

Question: What is difference b/w pre-production and post-production?

Pre-production is the work done on a product, especially a film or broadcast program before full-scale production begins.

The action of making or manufacturing from components or raw materials or the process of being so manufactured

The work that is done on a film or recording after filming or recording has taken place. Question: what is buffer shot?

Answer: A "buffer shot" is a film technique of inserting a shot into a film to disguise a mistake, or a cut. Buffer shots are often known as "cheat shots." For example, if Character A is talking to Character B and the microphone is briefly in shot while Character A is talking, the editor could insert a shot of Character B listening or reacting, to cover up the mistake. This technique is often used in news reporting when there is no opportunity for re-takes, or to cover up cuts in an interview. Question: What is film editing??

Answer: Film editing Film editing is part of the creative post-production process of filmmaking. The term film editing is derived from the traditional process of working with film, but now it increasingly involves the use of digital technology. The film editor works with the raw footage, selecting shots and combining them into sequences to create a finished motion picture. Film editing is described as an art or skill, the only art that is unique to cinema, separating filmmaking from other art forms that preceded it, although there are close parallels to the editing process in other art forms like poetry or novel writing. Film editing is often referred to as the "invisible art" because when it is well-practiced, the viewer can become so engaged that he or she is not even aware of the editor's work. On its most fundamental level, film editing is the art, technique, and practice of assembling shots into a coherent sequence. The job of an editor isn’t simply to mechanically put pieces of a film together, cut off film slates, or edit dialogue scenes. A film editor must creatively work with the layers of images, story, dialogue, music, pacing, as well as the actors' performances to effectively "re-imagine" and even rewrite the film to craft a cohesive whole. Editors usually play a dynamic role in the making of a film.

Question: when 1st camera was discovered and by whom?

Johann Zahn designed the first camera in 1685. But the first photograph was clicked by Joseph Nicephore Niepce in the year 1814. It was thousands of years back that an Iraqi scientist IbnalHaytham made a mention of this kind of a device in his book, Book of Optics in 1021. The earlier cameras were incapable of saving the images and were huge in size. The first practical photography was invented by Louis Daquerre in 1829 but he took almost 10 years to produce the effective method which was named after him as daquerreotype. All this was done in Niepce’s partnership.

Question: Define lens ratio

Answer;

When you look upon the front end of your lens barrel, you’ll see a ratio number (1:2.8, 1:2.8-4, 1:3.5-5.6, etc.), which is the maximum aperture of the lens. The aperture determines how much light the lens transmits to the image sensor. The lower the maximum aperture value will indicate the quality of the lens in terms of brightness. High quality zoom lenses deliver a constant f-stop throughout the focal range (i.e. a f/2.8 at 35mm and a f/2.8 at 80mm); whereas on a lower quality lens, the f-stop varies as you travel up the focal range (i.e. a f/3.5 at 28mm, but a f/5.6 at 80mm); you are losing at least one stop of light as you zoom up the focal length from wide angle to telephoto.

Question: What is Shutter speed??

In photography, shutter speed or exposure time is the length of time when the film or digital sensor inside the camera is exposed to light, also when a camera's shutter is open when taking a photograph. The amount of light that reaches the film or image sensor is proportional to the exposure time

Shutter speed isn’t particularly difficult; it is just the amount of time your camera spends taking a picture. This could be 1/100 of a second, or 1/10 of a second, or three seconds, or five minutes. Some people build custom cameras that take decades to capture a single photo.

Question: what is Reel?

Reel, in motion pictures, a light circular frame with radial arms and a central axis, originally designed to hold approximately 1,000 feet (300 m) of 35-millimetre motion-picture film. ... A film was a “one-reeler,” a “two-realer,” or longer.

Question: why is camera movement important in film?

Answer?

Camera movement has the potential to function in many different ways, such as to direct the viewer's attention, reveal off-screen space, provide narrative information, or create expressive effects. The camera most frequently moves when an object moves within the frame, initiating reframing or a following shot. Reframing involves slight pans or tilts designed to maintain the balance of a composition during figure movement. A camera operator will reframe when a sitting person stands up, for instance, so as to keep the person in the frame and allow for appropriate head room. Such camera movement draws attention to itself and is typically used sparingly to emphasize significant narrative details.

Question: What Is Exposure in Cameras?

Answer?

There are only two camera settings that affect the actual “luminous exposure” of an image: shutter speed and aperture. The third setting, camera ISO, also affects the brightness of your photos, and it is equally important to understand. Also, you can brighten or darken a photo by editing it in post-processing software like Photoshop on your computer.
