Week Six - To Infinity



Hyper-focal Distance 
"The concept of hyperfocal distance is easy to understand: focus a lens at the hyperfocal distance and everything in the photograph from some near distance to infinity will be sharp." - http://www.dofmaster.com/hyperfocal.html 


Senor Array Types 

  • CCD (Charged Coupled Device)  
  • CMOS (Complementing Metal Oxide Semi-colour)
Pixels - [Effective and Inactive] 

Dynamic Range 
  • Ability of sensor to record high and low luminance 
  • SLR - Subject Luminance Range
  • Film - Known as Density Range
  • Blooming 


  • When light passes the lens of a digital camera and is captured by the CCD it is converted into an electrical charge. There is a limit to how much charge each pixel or photosite can store.  - http://en.mimi.hu/photography/blooming.html
