Introduction to the DSLR

Introduction to the DSLR

  • DSLR stands for Digital Single Lens Reflex.
  • It basically means a camera with on lens and a mirror which reflects the light, where pictures are recorded on a digital card instead of film. 
  • To get started, it's best to use the automatic settings to get accustomed to the camera:
    • set the dial to the green automatic mode.
    • make sure the lens is set to AF (autofocus) and not MF (manual focus).
    • push the shutter button down halfway- the camera will automatically focus on the subject.
    • push the button down the rest of the way to take the picture.
  • Canon: Outside of Auto
    • a great online tool that lets you play around with a virtual DSLR and the three primary camera settings: ISO, shutter speed and aperture.
  • Exposure
    • exposure is the amount of light a digital camera's sensor captures when a photo is taken.
    • too much light results in a washed out photo (overexposed).
    • too little light and the photo will be too dark (underexposed).
    • a camera's aperture, shutter speed and ISO settings directly affect exposure, but more importantly, they allow you to control how each photo will look.
  • Aperture
    • the aperture settings control the size of the lens opening that allows light into your camera.
    • you can blur the foreground and background that bracket your subject (known as shallow depth of field) by opening up the aperture with a low f-stop number.
  • Shutter Speed
    • the shutter speed setting controls how long the shutter opens to expose the image sensor to that light.
    • open it for just a millisecond and you can freeze a fast moving subject.
    • alternatively, you can show the movement of a fast moving subject by keeping iy open longer with a slow shutter speed. 
  • ISO
    • the ISO is how sensitive your image sensor is to light.
    • with the ISO setting, a camera's image sensor can be adjusted to detect more, or less light as needed for a good exposure.
    • the higher the ISO, the more sensitive the sensor will be, and the brighter the image will be.
    • the lower the ISO, the less light it's going to bring in, and the darker the image is going to be.
    • if you're shooting in low-light, you will want to boost your ISO so that the image will be brigher.
    • if you're shooting in a bright, sunny place, you'll want to lower your ISO, or the image will be overly-bright.
    • high ISO will cause graininess so as a rule, use the lowest ISO possible. 

Media Language

Media language refers to the ways in which meaning is created in media texts. Below are some of the terms we have been learning about in our AS Media Studies lessons.

Camera:


  • Establishing shot: The opening shot in a dramatic scene that establishes the disposition of people and objects in the mise en scene. As such it is usually a wide shot, and is likely to be followed by a succession of closer shot.

  • Two-shot: A shot in which two figures appear in the frame.


  • Point of View shot: A camera angle in which the viewer seems to see with the eyes of the character in the scene.

  • Over the Shoulder shot: A camera shot in which the subject of the shot is filmed from behind a person's head and shoulders, which are framed to one side in the foreground.
  • High-angle shot: A camera shot taken from a higher level than the subject, and angled down towards them. This shot can have the effect of diminishing the authority of the subject, making them look weak.

  • Low angle shot: A camera shot taken from a lower level than the subject, and angled up at them. This shot can have the effect of enhancing the authority of the subject, making them look powerful.

  • Canted angle: A cinematic device where the camera is physically placed at an angle so that vertical and horizontal surfaces appear diagonal.
  • Pan: A horizontal camera movement left-to-right or right-to-left on a fixed axis. The word is short for 'panoramic movement'. A pan following a moving object suggests that we are viewing it from the point of view of an observer.
  • Tilt: A camera movement up or down on a horizontal axis.
  • Tracking shot: A camera movement achieved by mounting the camera on a dolly and moving it along a track. Typically, tracking shots are used to follow characters or other objects in motion.


Sound:


  • Diegetic sound: Sound that can be heard by the characters in the world of film.
  • Non-diegetic sound: Sound that cannot be heard by the characters in the world of film.
  • Synchronous sound: Sound that is directly matched with what is being viewed. 
  • Sound bridge: Editing technique in which visual cuts are deliberately not matched with audio cuts. 
  • Dialogue: The conversation that happens between characters in a work of fiction, or the lines spoken by actors. 
  • Voiceover: A type of non-diegetic, asynchronous sound in which the audience hear a voice that does not have a source either within the frame or within hearing distance and which is not heard by the people on screen. 
  • Incidental music: Music used in a film or play as a background to create or enhance a particular atmosphere.
  • Stings: A short musical phrase primarily used as a form of punctuation.
  • Ambient sound: Sound which is natural to a setting.


Mise en scene:

  • Mise-en-scene: The look of a film, derived from its use of sets and settings, lighting, colour, costumes hair and make-up, props, actor movement, and the overall placement and visual composition of these elements by the director. 
  • Location: A 'real' place, as opposed to a studio, in which something is filmed or otherwise recorded.

  • Set: An interior that has been constructed to look like a real place when filmed; the set helps to identify the time and place in which a narrative will unfold. 


  • Costume: The clothes worn by characters in a fictional text. The costumes are part of the mise en scene and as such are an important part of signification (for example, as a generic or period identifier). 


  • Make-up: Cosmetics used to change the appearance of a performer. 


  • Prop: Short for 'property'. A small item used in a film or TV production to add realism, assist with the narrative or act as a motif. 


  • High-key lighting: Lighting which eliminates most of the shadows.



  • Low-key lighting: Lighting which emphasises shadows.


Editing:
  • Cut: The commonest form of edit in moving image texts, this is the instantaneous change from one shot to another in an edit. 
  • Shot/reverse shot: A convention for showing a dialogue sequence. We cut between the two speakers, showing each person's point of view. 
  • Eye-line match: A visual code used to make it clear what the subject is looking at
  • Graphic match: A compositional device onscreen, whereby objects of common characteristics of shape or colour are used in successful shots. 
  • Match on action: Two shots in which an action begun in the first is completed in the second, thus disguising the fact that there has been a cut.
  • Dissolve: In editing, a cross-fade between two shots: one fades out as another fades in.
  • Wipe: A shot transition in which the new image wipes over the previous one.
  • Superimposition: To place one image over the top of another on the screen.
  • Long take: Not to be confused with a long shot, a long take is a shot of comparatively long duration.
  • Montage: The production of a rapid succession of images in a motion picture, usually accompanied by music, to illustrate an association of ideas or a passing of time.
  • Post-production: The various processes that take place after filming in order to create the final cut of a film.
