[. . . ] To ensure repeatable and consistent measurements and to be aware of the dynamic range of a particular type of film or digital camera before making a photograph, The DIGITALMASTER L-758 series can be programmed to store, recall and display up to three different digital cameras or film types. For information about supported models, visit the Sekonic website. http://www. sekonic. co. jp/English/ (1) Testing for Exposure Profiling a) Introduction 1) Settings * Compensation Value Compensation value is the difference between the metered value of a hand-held meter and a specific camera (aperture and shutter speed). Compensation adjustment is within a +/- 5EV range in 1/10 step increments. * Clipping Point (-) The point at which a given lighting situation (pre-exposure) has surpassed the responds level of a sensor or film and alerts the shooter of an over or under exposure situation (Pre-Exposure Warning). These point can be custom set from -7EV to +0EV in 1/10 increments. * Dynamic Range (-) The point at which the sensor or film has reached its maximum reproducible shadow details minimum pixel noise or grain. Dynamic range (-) adjustment is set from -7EV to 0EV in 1/10 step increments. * Dynamic Range (+) The point at which the sensor or film has reached its maximum reproducible highlight details without blooming or highlight block up. Dynamic range (+) adjustment is set from 0EV to +7EV in 1/10 step increments. * Clipping Point (+) The point at which a given lighting situation (pre-exposure) has surpassed the responds level of a sensor or film and alerts the shooter of an over or under exposure situation (Pre-Exposure Warning). These point can be custom set from 0EV to +7EV in 1/10 increments. 39 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 as user defined limits for a specific type of out media like a printer. In this case, simply enter the dynamic range data in the clipping point cells and the clipping points in the dynamic range cells. The following are the setting values of each middle-tone, clipping point (-), dynamic range (-), dynamic range (+), and clipping point (+) values used by Sekonic. Standard Exposure Value Clipping Point (-) Dynamic Range (-) Dynamic Range (+) Clipping Point (+) 118 20 35 230 245 Reference You may have other standards or needs that require the use of different settings. (Page 58) 40 All of these settings can be entered using the ISO sensitivity (from ISO3 to 8000, in 1/3 step). In addition, you can configure individual settings for up to three exposure profiling (cameras, type of compressed file, etc. ). Exposure Profiling Exposure Profile 1 CAMERA 1 Exposure Profile 2 CAMERA 2 Exposure Profile 3 CAMERA 3 2) Procedure for Exposure Profiling 1 Prepare the equipment required 2 Set up the equipments so it cannot move during test shooting. Also ensure that the "Exposure Profile Target" is illuminated evenly. 3 Make bracketed exposures according to each combination of the light source type (ambient or flash) and the ISO value (ISO3 to ISO8000) as required. 4 Use the info function of your image-editing software and find the setting values with the G-level of RGB readout. NOTE! Data Transfer Software and Software Guide (Testing procedure, Image analyzing and Data enter) are preliminary for still photography use. For more information, please visit us at www. sekonic. co. jp or www. sekonic. com 41 b) Preparing Equipment Prepare the equipment required for shooting the test target. Camera Mount the lens that you use most often. Light meter Since measurements of incident light and reflected light are required, use of the Sekonic L-758DR(L-758D/758CINE) or other light meter with built-in incident/reflective spot measurement is recommended. Tripod Since hand movement when shooting with long exposure can affect test shot results, use of a tripod is recommended. [. . . ] Select the setting you want from the list or enter the value that was calculated automatically. For details about setting values, see "Camera Exposure Profiling". (Page 38) Enter values for all of the settings that require entry. For details about setting values, see "Camera Exposure Profiling". [. . . ]
