  • Page 48: Camera Exposure Profiling

    The L-758DR (L-758D/L-758CINE) can be pro- grammed to match the sensitivity of film or digital camera sensor for prefect exposure control. In addition, since film and digital cameras have their own unique dynamic range, clipping point (expo- sure tolerance) and varying ISO sensitivity they need to be profiled.
  • Page 49 It is necessary to test the cameras sensitivity, measure the actual dynamic range and know the clipping points of your digital camera and/or type of film and processing used before programming the L-758DR (L-758D/L-758CINE) meter for Exposure Profiling. Film exposures should be evalu- ated by scanning the film first and then evaluating the images in a photo application software.
