WEEK 5- DIGITAL PHOTOGRAPHY

The main parts of the camera:
1. Camera body
➛shutter
➛image sensor
➛LCD screen

2. Camera lens
➛aperture/iris
Fig 1.1 Main parts of a camera

Exposure setting:

1. Iris/Aperture
  • control the flow of light entering the lens
  • measured by f-stop, indicated by sequence of f-number: (refer fig1.6)
  • the lower the f-number, the larger the lens opening
Fig 1.2 Sequence of f-number

2. Shutter 
  • small plastic sheet that opens and closes to allow or prevent light from reaching the film
  • shutter speed is measured in seconds: 1/1000 s,1/500 s,1/250 s,1/125 s,1/60 s,1/30 s,1/15 s,1/8 s,1/4 s,1/2 s,1 s, 2 s, 3 s…

3. ISO
  • originally referred to the sensitivity of film
  • in digital photography, ISO refers to the sensitivity of the camera's sensor
  • common ISO camera settings: 100, 200, 400, 640, 800, 1600, 3200, 6400….
  • the lower the number of ISO, the less sensitive your camera is to light and the finer the grain

Fig 1.6 ISO


Lens perspective:

  • types of lens: wide angle lens, standard lens and tele lens
  • appropriate lens provided desire framing, lens choice affects angle of view
Fig 1.7 Type of lenses

1. Focal Length
  • the shorter the focal length, the wider the angle of view and vice-versa
Fig 1.8 Focal length

2. Depth of field
  • the proportion of the image that is reasonably sharp & in focus
  • the smaller the aperture used, the greater the depth of field
Fig 1.9 Depth of Field
  • wide angle lens is useful for landscape photography or street photography

To start, I used the Color Shades Finder tool to refine the color palette. One of the issues with the Watsons app is its lack of a consistent color theme. While the current colors somewhat represent the brand and make the app recognizable, they can also feel overly distracting. For the high-fidelity prototype, I focused on creating a more cohesive and simple color theme. In the existing app, green, blue, pink, and various gradients are frequently used. For this redesign, I chose colors...
