Triangle of Exposure


1. Aperture: the opening through which light passes through a photographic instrument, which can be adjusted to variably open the amount of light that enters a camera.

2. Shutter Speed: the time of exposure, or the effective length of a camera's shutter is open.
3. ISO: is the standard measure of light sensitivity for the imaging medium. In other words, the film speed. 

4. Depth of Field: The distance between the nearest and the furthest objects that an image can have focus in.

5. Motion Blur: the streaking of rapidly moving objects in a still image.

6. Noise and light sensitivity: the variation of brightness or color information in images, as a by-produce of image capture that adds spurious and extraneous information.

Print vs. Digital

5 Positives of Digital Photography

  • Instant feedback regarding photo taken
  • Convenience with a large volume of photos taken
  • Portability, designed to be relatively portable with the whole apparatus
  • Easy sharing photos via electronics
  • No prints, no excess copies and photographic messes around


5 Negatives of Digital Photography

  • Complexity of programs and different versions
  • Necessity of a Computer at hand
  • High costs (computer, camera, transfer docks, etc)
  • Battery life is limiting
  • Electronic failures, such as hacking or virus can destroy and tamper with photos


5 Positives of Print Photography

  • Resolution. Good film easily beats the resolution of digital
  • Work in many places, such as very humid or very hot places that would disturb 
  • Cheap start in comparison to digital photography
  • Great dynamic range
  • Good archival properties

5 Negatives of Print Photography

  • Low light performanace
  • Difficulty and inconvenience of using and obtaining film stock in comparison
  • Limit in post processing
  • Delay of waiting for print
  • Storage takes up space
