1、Basic Film Production,Production Phases,There are three phases of production common to most professionally produced motion pictures. These are: Preproduction phase Production phase Postproduction phase, 高压油管 金属软管 液压接头 ,Preproduction Phase,In general, the preproduction phase encompasses all aspects o

2、f preparation that are performed before the camera starts to roll. Some aspects of preproduction include:,Screenwriting Storyboarding Funding Assembling a crew Casting Costume Design Location Scouting Set Design Properties (“props”) Scheduling,Preproduction Phase,Screenplay/Script: The screenplay su

3、pplies the general plan for the production of a film. There are two types: The “spec” script The “shooting” script,Preproduction Phase,The “Spec” (Speculation) Script is the version of a screenplay that writers distribute to producers in the hope that it will be “optioned” (i.e. considered for produ

4、ction). It primarily contains: Slug-Line (brief description of the setting, e.g. “INT. ROOM DAY” which means the interior of a room during the day) Business (descriptions of characters/action) Dialog (the lines intended to be spoken by the actors),Preproduction Phase,The Shooting Script is a much mo

5、re detailed version of the spec script that includes numbered scenes, specific camera angles and other technical information. An example of a page from a shooting script (from the film Pieces by Andrew Halasz shot here at William Paterson) can be seen on the next slide.,Preproduction Phase,Writing a

6、 screenplay and analyzing a film narrative require an awareness of similar concepts: Character Conflict Action Story Plot,Preproduction Phase,Character Agent of physical and social action Subject to physical and social action Subject to needs and desires Subject to social norms, mores, and laws,Prep

7、roduction Phase,In an instructional book on screenwriting, Syd Field (1979) divides character into interior and exterior aspects. Viewers of a film dont have access to the characters interior life and so it must be expressed in the exterior life through actions taken in professional, personal, and p

8、rivate contexts. One pursuit of narrative analysis is the interpretation of character motives based on action.,Preproduction Phase,Preproduction Phase,Conflict The source of narrative conflict is the needs and desires of the character when they are met with oppositional forces. There are three basic

9、 types of narrative conflict: Character versus Nature (i.e. the physical world) Character versus Character Character versus Self,Preproduction Phase,Action In a film narrative, a character is expressed through his/her actions in responding to a conflict. Two overlapping types of character action are

10、: Social Action (e.g. dialog, communicative behavior) Physical Action (e.g. stunts, athletic behavior),Preproduction Phase,Storyboarding: A storyboard is a series of drawings intended to represent how the film will be shot, including how each frame will be composed and how subject and camera motion

11、will occur. The storyboard articulates the mise-en-scene of the film. Mise-en-scene: All of the elements that compose the shot.,Preproduction Phase,Funding: Films are generally expensive to produce. Even small independent productions with unknown actors can cost hundreds of thousands of dollars. Bec

12、ause of the level of investment involved, most films rely on either production companies (“Hollywood” films) or independent investors (“Independent” films).,Preproduction Phase,Assembling a Crew: A crew is the group of workers on a film set who are responsible for facilitating production (as opposed

13、 to acting). Although large productions may employ many crew members in many different departments, there are only a few basic positions which are detailed later in the production phase.,Preproduction Phase,Casting: Choosing actors to play roles. Costume Design: Choosing or designing the clothing/co

14、stumes that the actors wear. Location Scouting: Choosing the locations where the film will be shot. Set Design: Constructing sets where the film will be shot.,Preproduction Phase,Properties (“Props”): Choosing the tools and objects used in the film. Scheduling: Coordinating all aspects necessary to

15、the production.,Production Phase,The production phase refers to the period of time when the film is actually being shot. Some aspects of production include:,Direction Camera operation Lighting Sound recording Acting,Production Phase,During production, these roles are usually delegated to the product

16、ion departments listed on the next two slides.,Production Phase,Production Departments Direction Director (oversees all aspects of the production) Assistant Director (works closely with the actors) Camera Cinematographer (oversees camera operation and lighting plan) Camera Operator (operates the cam

17、era) Assistant Camera (loads camera, pulls focus) Lighting Cinematographer (oversees camera operation and lighting plan) Gaffer (head electrician) Grip (sets up lights),Production Phase,Production Departments (continued) Sound Sound Mixer (records the sound) Boom operator (positions the microphone)

18、Clapper (displays the clap slate for the camera) Talent Actors (perform before the camera) Miscellaneous Production Coordinator (scheduling) Continuity “script girl” (watch for continuity errors) Make-up Artist (apply make-up to actors) Production Assistant (various jobs),Production Phase,All of the

19、 departments and positions described on the last two slides serve one goal: to capture the sound and image necessary to tell the story. Although going into every detail of production is far beyond the scope of this course, lets consider the “nuts and bolts” that go into filmmaking.,Production Phase,

20、How does the camera work? When we are watching a motion picture, we are actually watching a rapid series of still images that are projected in rapid succession on the screen. We are able to perceive motion in a film because of the cognitive/perceptual phenomenon known as persistence of vision.,Produ

21、ction Phase,How does the camera work? The motion picture camera is a tool used to rapidly expose a continuous series of film frames to light that is reflected off of objects and focused onto the film by the cameras lens. The following three slides display diagrams of the inside of a basic motion pic

22、ture camera.,Production Phase,How does the camera work? As you can see, the film makes its way from the spool into the loop and through the gate. The aperture in the gate is a small square hole that allows light to pass from the lens onto the focal plane of the film. This process is represented in t

23、he diagram on the left of the next slide.,Production Phase,How does the camera work? Once light has been focused by the lens, the camera shutter opens. The shutter is shaped like a revolving disc and its function is to allow a single frame of film to be exposed to light ONLY when it is completely mo

24、tionless inside the gate. This normally occurs 24 times per second. See the following slide for shutter operation.,Production Phase,How does the film record the image? In the instant that the shutter opens and closes, exposing the film frame to light, a chemical reaction takes place on the surface o

25、f the film. The coating of emulsion, which is composed of light-sensitive silver halide, is burned away in various degrees (depending on the intensity of the light) leaving behind a “latent image” that is revealed once the film has been processed. The following two slide illustrates this.,Production

26、 Phase,Shot / Mastershot The 180 degree rule.,Production Phase,Now that we understand the basic mechanism, lets consider some of the ways that it can be manipulated during production: Types of shots Types of angles Lens choice Movement Lighting,Production Phase,Types of Shots There are four basic sh

27、ot types that are based on the apparent proximity of the subject. Long shot Full Shot Medium shot Close up shot,Production Phase,Types of Shots The Long Shot (a.k.a. Establishing Shot) In the most pragmatic sense, long shots can be used to establish a location, acquainting the viewer with the onscre

28、en space so that the sequence of shots that follow is not disorienting. Long shots can also be used to suggest a wide variety of meanings such as isolation, loneliness, freedom, emotional distance, and more. (Note that interpreting any particular shot or sequence of shots is dependent upon the conte

29、xt of the film.),Production Phase,Types of Shots Full and Medium Shots Full shots include the entire body of a subject from top to bottom while medium shots generally include the body from the waist up. Full and medium shots tend to mimic our point of view when we are engaged in a social encounters.

30、,Production Phase,Types of Shots The Close-Up Shot Close-up shots capture a single object, or feature within the frame. They are commonly used to reveal subtleties and/or create a sense of engagement or intensity.,Production Phase,Types of Angles There are three basic types of angles which refer to

31、the position of the frame with respect to the subject within the frame. High Angle Low Angle Straight-On Angle,Production Phase,Types of Angles High Angle A high angle shot refers to a camera position where the lens aims down at the subject from above. An extreme high angle is sometimes referred to

32、as “birds eye view.” High angles can be used to reveal the layout of a room or to make a subject appear weak and small. As mentioned previously, however, the context of the scene and the larger film must be taken into account prior to interpretation.,Production Phase,Types of Angles Low Angle A low

33、angle shot refers to a camera position where the lens aims up at the subject from below. As opposed to the high angle shot, the low angle tends to make the subject appear intimidating and powerful. Again, the larger context of the film must be accounted for.,Production Phase,Types of Angles Straight

34、-On Angle A Straight-On shot refers to a camera position where the lens is aimed directly at the subject. Especially when used in conjunction with the full or medium shot, this angle mimics our point of view in a social encounter.,Production Phase,Lens Choice The only function of a lens is to focus

35、the light that is either projected or reflected from the surrounding environment onto the focal plane of the film. However, lenses come in a variety of focal-lengths which make the depicted scene appear at different distances. There are three basic types of lenses: Telephoto lens (a “long” lens) Wid

36、e angle lens (a “short” lens) Normal lens Zoom lens The image on the next slide shows the basic function of a lens.,Production Phase,Lens Choice Lens choice is guided by two primary and strongly related factors: Focal Length: The distance perspective of the lens. Depth of Field: The range of distanc

37、e that can focused in front of the lens.,Production Phase,Lens Choice Telephoto Lens The focal length of a “telephoto” lens results in a magnified perspective, not unlike a telescope, which makes objects appear closer than they actually are when viewed with the naked eye. The telephoto lens has a re

38、latively shallow depth of field, meaning that only a narrow range of space before the lens can be put into focus. It also tends to compress the foreground and background of the field, making images look flat or two-dimensional.,Production Phase,Lens Choice Wide Angle Lens In direct opposition to the

39、 telephoto lens, the focal length of the wide angle results in a distanced perspective, which makes things appear further away than they actually are when viewed with the naked eye. The wide angle lens has a relatively deep field, meaning that a vast distance of space before the lens can be put into

40、 focus. It also tends to create a more three dimensional effect. An extreme wide angle lens is sometimes referred to as a “fish eye” lens.,Production Phase,Lens Choice Normal Lens The focal length of the “normal” lens is similar to the actual distance of objects in the field of view when viewed with

41、 the naked eye. Zoom Lens The focal length of the “zoom” lens is able to be manipulated while in use, and can range from telephoto focal lengths to wide-angle focal lengths.,Production Phase,Camera Movement Camera movement guides the perspective of the spectator and causes him/her to attend to those

42、 events and features which are most important to the narrative and aesthetic of the film. There are five basic forms of camera movement: Panning Tilting Tracking Trucking Booming Crane Hand-Held,Production Phase,Camera Movement Panning Panning refers to the left to right or right to left movement of

43、 the camera as it remains on a single axis. This is demonstrated graphically on the following slide. Tilting Tilting refers to the down to up or up to down movement of a camera while it remains on a single axis.,Production Phase,Camera Movement Tracking Tracking refers to the sideways movement of th

44、e camera as it captures a scene. Trucking Trucking refers to the forwards or backwards movement of the camera as it captures a scene. (These are demonstrated graphically on the following two slides.),Production Phase,Camera Movement Booming Booming refers to the vertical movement of the camera as it

45、 captures a scene. Craning Crane shots permit a wide range of sweeping motion and height in capturing a shot. This is demonstrated graphically on the next slide.,Production Phase,Camera Movement Hand-Held Just as the name indicates, hand-held camera movement is performed without the assistance of a

46、dolly or tripod. Hand held shots tend to have convey the subjective point of view of a character since they imitate a first-person perspective. Hand held shots are commonly used in “slasher” films to create a feeling of panic. Steadicam: A steadicam is camera mount that is attached to the operators

47、body. It serves to reduce jerky movements and create the sense of a steady flow through space.,Production Phase,Lighting Lighting refers to how a scene is lit, and, to a large extent, how it is exposed on film. It is among the most complex and important aspects of production and can be divided into

48、two categories based on location and two categories based on style. Location (Indoor versus Outdoor lighting) Lighting Scheme (High Key versus Low Key lighting),Production Phase,Lighting Location Indoor lighting Indoor lighting is generally achieved through the use of specialized lamps with varying

49、characteristics of directionality (focus), throw (distance), and intensity (brightness). There are three lights in a basic lighting setup (also see the next slide): Key Light (provides the primary source of illumination) Fill Light (illuminates the shadows left by the key light) Back Light (separate

50、s the foreground from the background),Production Phase,Lighting Location Outdoor Lighting Outdoor lighting is generally done with large, powerful lamps known as HMIs. In addition to lamps, other devices such as reflectors, flags, and neutral density gel may be used to increase or reduce the intensit

51、y of sunlight on various parts of the scene.,Production Phase,Lighting Lighting Scheme High Key High key lighting is a style in which the ratio of the key light to the fill light is high and, thus, fills in most of the shadows in the scene resulting in a bright, evenly lit image. High key lighting i

52、s often used in light-hearted comedies and dramas.,Production Phase,Lighting Lighting Scheme Low Key In opposition to high key, low key lighting refers to a low ratio of fill to key light, which results in a darker image with more “contrast” and shadows. This scheme is most often associated with fil

53、m noire crime stories of the 1940s but is also frequently used in horror films and early German expressionist work.,Production Phase,It is the job of the director and cinematographer to coordinate these elements into a strategy for capturing the action on film. One common and efficient strategy is r

54、eferred to as Shot / Mastershot or Shooting for Coverage. This technique involves shooting a full shot of the entire scene before moving in closer on a re-shoot to capture more specific cutaway shots that can later be coordinated with the master. (Continued on the next slide.),Production Phase,Anoth

55、er strategy that is commonly employed in directing a scene is the 180 rule, which posits that the camera should take angles on only one side of the axis of action. The reason for this is that shooting on both sides of the action changes the background and may disorient the spectator. Adding an estab

56、lishing shot or tracking the camera across the axis of action can prevent this.,Production Phase,Sound Recording Sound recording is treated separately here because, in traditional film production, it is recorded completely independently from the image. This is known as “double system” sound recordin

57、g. Generally speaking, there are at least four soundtracks in any feature length narrative film: 1 the sound effects track. 2 the music track. 3 the room tone track. 4 the dialog track.,Production Phase,Sound Recording Sound Effects For the most part, sound effects are obtained separately by a “fole

58、y” artist who coordinates sound effects in synchronization with the onscreen action through a process known as “looping” where a portion of the film is repeatedly played to perfect the timing of the sound effects. This is considered to be part of post-production which we will cover next. Alternative

59、ly, for low-budget productions, libraries of prerecorded sound effects can be used or sounds can be recorded during production by the sound mixer and boom operator.,Production Phase,Sound Recording Music Film music is either purchased (if it is not in the “public domain”) or scored specifically for the production. Music that is scored is done in similar fashion to foley sound in the sense that film is playing during the recording session to enhance timing.,Production Phase,Sound Recording Room Tone Room tone is recorded silence. Normally, once all of the dialog is recorded, the sound mixer as
