7. Camera Exposure Profiling 1. Calibration testing for exposure profiling A camera exposure profile plays two main roles. [1] It can be used to display on a light meter the unique dynamic range and clipping point of the digital camera you are using. [2] To display more accurate exposure values on the light meter, it records unique variations in the camera, lens shutter speed, aperture, etc. that you are using and reflects them in the exposure display.
It is necessary to test the cameras sensitivity, measure the actual dynamic range and know the clipping points of your digital camera and processing used before programming the L-758DR (L758D/L-758CINE) meter for Exposure Profiling. Reference: • The dynamic range settings and the clipping point settings can be switched, if it is necessary to create clipping points within the dynamic range.
7. Camera Exposure Profiling 2. How to set the Camera Exposure Profiling There are two ways to input the result of the test target data into the light meter: 1) Sekonic Data Transfer Software - install application software from the included CD-ROM and connect the computer and light meter via USB, and 2) Direct Input - Manually enter the test target data directly into the light meter. 2-1 Sekonic Application Software Data Transfer Software is included with the L-758DR, L-758D and L-758CINE.
2-2 Manual Input of Exposure Profile It situations where it is not possible or convenient to use a computer or the Sekonic Data Transfer Software, Exposure Profile data can be entered into the L-758DR (L-758D or L-758CINE) directly. Below is the step by step process for manually entering a specific Exposure Profile. 1) With the meter turned off,enter the Camera Exposure Profiling mode by pressing the Power button while pressing the AVE../ EV button at the same time. ENGLISH 7.
7. Camera Exposure Profiling 7) Setting compensation value Rotate the Jog wheel while holding down ISO1 button and ISO2 button simultaneously. Compensation values can be made in 1/10 step increments in +/-5.0EV. 8) Setting Dynamic range (-) Rotate the Jog wheel while pressing AVE./ EV button . Dynamic range can be set from -7 to 0EV in 1/10 step increments.
7. Camera Exposure Profiling NOTE: ENGLISH 11) Setting Dynamic range (+) Rotate the Jog wheel while pressing ISO2 button . Dynamic range can be set from 0 to +7EV in 1/10 step increments. • Only when you enter the data manually, the setting value is not the step from the middle tone (0), but the step from the the edge of clipping point (+). Ex) When the clipping point (+) is 2.5 and the dynamic range (+) is 3.5, the step of dynamic range (+) to enter is 1.0.
7. Camera Exposure Profiling 3. How to use Camera Exposure Profiling 3-1 Selecting Camera Exposure Profiling Preset Camera Exposure Profiles (Camera 1, 2 and 3) can be recalled. 1) Hold down the ISO 1 button , and press the MID.TONE button to select the desired Camera profile (Camera 1, 2 or 3). NOTE: • Holding down the MID.TONE button first and pressing ISO1 button makes the last measurement value “Mid.Tone” as standard value. Be sure to hold the ISO1 button first and press the MID.
1) After taking a measurement by pressing the Measuring button ,pressing either the Memory button ,MID.TONE button or AVE./ EV button stores the measured value as zero in the middle of the EV scale representing the MID.TONE value. Pressing MID.TONE button will display a blinking “ ” on the scale. Pressing AVE./ EV button will display a blinking “ ” on the scale. If the MID.TONE button is not pressed,the measured value will be set automatically in the middle of the EV scale.
7. Camera Exposure Profiling 3-2-3 MID.TONE button This button is used to set the measured value in the middle of EV scale. 1) Take a measurement by pressing the Measuring button . Press MID.TONE button to set the Mid.Tone on the scale. ” ” in the middle of the EV scale will blink continuously twice to indicate that the Mid.Tone has been set.
4) Setting Mid.Tone Value from Memorized Values After storing some measurements in memory, it is possible to set Mid-Tone value from memorized values. First enter the memory recall mode by holding the MODE button, and pressing the Memory button. Select one of the memorized values by rotating the Jog wheel and then press the MID.TONE button to set it as the Mid-tone value. ENGLISH 7. Camera Exposure Profiling Memory button Memory recall mode NOTE: Select desired memorized value as Mid.Tone Press MID.
