Pros/Cons of Shooting in RAW
  • Pros:

    • larger file = more information
    • can capture in 16bit
    • higher quality image in photoshop
  • Cons:
    • each file must be processed individually
    • larger files use more memory space
    • may not be necessary to always shoot RAW
Camera Raw Functions
  • white balance
  • clipping
    • cause darkest or lightest details in image to shift to pure black or pure white
    • lose all detail in that part of image
  • exposure
    • white clipping adjustment
    • large increases = increased shadow noise
    • large movements in highlight values = stretch information in shadow values
  • blacks
  • brightness
  • contrast
  • clarity, vibrance, saturation
