  • Page 33: Flash Analyzing Function

    Reference: • Slower shutter speeds allow more available light to reach the film or digital camera sensor, and faster shutter speeds reduce the amount of available reaching the film or sensor. • The settings above are made by adjusting the ambient light by the shutter speed. It is also possible to modify the ratio by adjusting the flash light (when changing the distance between the flash and the subject or when changing the amount of light of the flash).

  • Page 48: Camera Exposure Profiling, Calibration Testing For 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.
