Intro to Phtography (Note)

The first time I try using a DSRL camera, it was not as easy as I thought it be. I thought it would magically give you beautiful picture, but that wasn't the case you need skill to go with it. Auto was ok for a while but I just want to learn a better way to do it.

  • Aperture - The size of the opening of the lens 
    • Bigger the size the more light come through 
    • F-number 
      •  Small = bigger aperture  
      • Big = smaller aperture
    • Depth of Field - how much of image is in focus 
      • Shallow - subject is it focus but not the foreground or background (need smaller F-number )
      • Wide/ Large - a lot of the image is in focus 
shallow depth of field / low f number / more light in (big aperture)

wide depth of field / high f number /  less light in (small aperture)
  • Shutter speed -how fast shutter open and close / how long exposure
    • high shutter speed = less exposure
    • sharper, still picture
fast exposure/ give no time to move = still
slow exposure/ allow blur


  • ISO - sensitivity to light 
    • higher = more noise / grain (dotted) desaturated or over saturated
