final exam comp

• basic light positions

  • backlit
  • front lit
  • side lit
  • top-lit
  • bottom lit
• backlit - Subject will appear dark with the light source behind it.
• front lit - Subject will be well lighted, but their eyes will squint.
• Side lit - Will create harsh lighting effect that accentuates contours.
• Top-lit - Bottom shadows will be prominent and deep.
• Bottom lit - Long upward shadows produce an unsettling mood.
• following devices are designed to be used with a smartphone.

  • tripod
  • selfie stick
  • stabilizer
  • drone
• tripod - Is an extendable three-legged support for the smartphone and is used to keep the camera fixed on one spot with the lens trained at the subject.
• Selfie Stick - Used for photo or video selfies where you shoot or record yourself on video.
• Stabilizer (Gimbal) - Can either be motorized or non-motorized. Either way it’s meant to counter any unward movement of the camera that takes its focus away from the subject.
• Drone - Unmanned flying machine  that’s controlled by remote control using a smartphone attached to a transmitting and receiving command antenna.
• The James Bond films released prior to 2006 are well known for this, depecting characters taking pictures using clandestine devices, such as pen camera
• In the movie, Charlie’s Angels: Full throttle (2003), a mobile phone (sony ericsson t616) with a real camera was featured as a novel spy devices
• T616 is now a virtual dinosaur
• smartphones and their camera are run by a mobile operating system
• three types of mobile operating system:

  • android (google)

  • ios (apple)

  • windows (microsoft)
• microsoft, in 2016, decided to leave the mobile phone race to its two competitors
• mobile phones have become commonplace devices since the mid-1990s
• reflex camera - type of camera used by professional photographers that has a body with a flipping mirror and prism on which s movable lend system is attached
• single-lens reflex (SLR) - it allows user to see exactly the image that is captured by the lens
• viewfinder - the part of camera the photographer looks into to compose the picture
• mirrorless camera - the lates incarnation of the reflex camera
• DSLR - it used a small view screen that acts the same way as the viewfinder of an SLR
• view screen - is more suitable for when a video is being taken
• videography - evolved from filmography with the transition of capturing and storing moving images from film to tape to digital devices
• video-capturing mediums - defined the evolution of filmography to the videography that is known today
• celluloid film - strip of transparent plastic or celluloid which is coated on one side by light-absorbing crystals and creates an image when exposed to light
• memory card - used in digital video camera to store digital audio, i mage, and video files that are readable snd displayable by the host device
• Smart phone camera has become the direct competitors to the digital SLR cameras
• videography - essentially a collection of methods designed to control how light reaches the film or the camera sensor in order to capture the images desired
• in a smart phone, there are three parts that manipulate lights when shooting a video:

  • the lens assembly

  • the sensor

  • the screen
• some lens setups are designed to respond to the users focusing commands in a process called computational photography which pieces together the best parts of a subject photographed at the same time with different lens sizes and operators
• sensor - photo sensitive plate device that created a video file, which is a dile that contains information on a succession of images
• 2 types of image sensors: charged couple device (ccd) and complementary metal oxide semiconductor (CMOS)
• CCD - more expensive, captured pictures as a whole, in much the same way an image would be captured on celluloid film or by an SLR camera
• CMOS - used in smartphones because it is compact, makes use of scanning
• screen - serves as the window of what the lens can “see”
• magnetic tape - a plastic strip, thats rolled in a rectangular housing comes in diff widths and sizes, is also called audio tape or video tape
• magnetic tape - it has magnetic particles which form pattern that can be read as audio or video
• SLR - a single lens reflex camera that uses film
