camera vs eye
Camera vs Eye
  • Eye sees a wider range of color luminance than digital cameras
  • HDR’s images compensate for this by combining three or more digital images
  • Normal exposure, overexposed and underexposed, easy to do with midrange or better Canon cameras
  • More than three images can be used, Nikon gear can do 5 or 7 easily
why three images
Why three images?
  • Normal exposure for camera’s best
  • Over exposed gets stuff in shadows
  • Underexpose gets stuff that is blown out
  • Consider case of room with window looking out on bright scene

tone mapping
Tone Mapping
  • HDR needs tone mapping to display colors on monitor. Way too many colors at first.
  • Every photo is different but as a start try:
    • Strength 100%
    • Color saturation reasonable
    • Luminosity, less contrast to right
    • Microcontrast I like a lot but play around
    • Smoothing “HDRness” of shot, middle 3 mostly
tone mapping continues
Tone Mapping Continues
  • White and Black Point, Gamma adjust to get histogram inside box
