[. . . ] For this reason, the Starlite can also be set additionally to half time values. The selection is made activating the DIP 2 switch: ­ 1/1 full time values Exposure times are displayed in 1/1 full time values or when using the CINE function, in the standard CINE film speeds. ­ 1/2 half time values Exposure times are displayed in 1/2 half time values. With this function, additional CINE speeds are displayed. DIP 2 20 GOSSEN Foto- und Lichtmeßtechnik 5. 7 Taking measurements in the zone system This function is mainly used to cope with subject contrasts in the field of black and white photography. In addition to the influence of illumination, there is a further possibility of optimizing the contrast range of film and paper. The zone system allows details to be reproduced in the picture which otherwise would not be visible and would be lost. A detailed analysis of this technique would, however, go beyond the scope of these instructions. 5. 7. 1 The Starlite and the zone system The Starlite allocates different brightness ranges to predefined graduated zones of grey. Variations of these grey tones from the middle zone determine the exposure correction and the changes in the development process, which are to be applied correspondingly. Taking measurements in the zone system For using the zone system activate the switch DIP 4 in the battery compartment. ­ Set the diffusor ring at the mesuring head to the , , reflected light ­ 1°". ­ Keep the left function button pressed and select the sub-function ZONE using the setting wheel. ­ Using the viewfinder, focus on the darkest spot of the subject, which should still be shown up in the negative. value will then be automatically allocated to zone V. ­ Using the setting wheel, place the measuring value in the zone where the darkest value should be, e. g. ­ Now you can measure up to 8 further spots in the subject using the measuring button ­ the most important brightest spot, which should still show detail in the negative, must be included. GOSSEN Foto- und Lichtmeßtechnik 21 After each measurement using the measuring button the following data are stored and displayed: ­ the symbol ZONE and the last measured value are displayed on the left ­ the number of measurements made are displayed on the right (4 measurements in the example) ­ on the zone scale the currently measured values are indicated (identical values only once) and the average of the brightest and the darkest spot as a flashing dot When the measuring process is completed and you then switch over to the function , , ambient light" and the desired measuring function, the value measured in the zone V is displayed as shutter speed/f-stop combination. Additionally, the flashing ZONE symbol is displayed. Now, you can select further shutter speed/f-stop combinations using the setting wheel. If, by mistake, you take a zone measurement in the incident light mode (flat or spherical diffuser), you are reminded by the flashing diffusor symbol that you have to set the diffuser ring to 1° spot metering. Note down the subject contrast for the film development and adjust the development time in accordance with the contrast range. 22 GOSSEN Foto- und Lichtmeßtechnik 6 Measuring functions­ Flash light ­ Trigger flash When using a sync cord, the flash is triggered and measured automatically when pressing . ­ The measured f-number (sum of flash light and ambient light) appears both in the left digital display (resolution 1/10 stops) and as a flashing indicator in the analogue scale rounded to the nearest 1/2 f-number. In addition to this, the f-stop for the share of the ambient light is displayed on the analogue scale, not flashing. In essence, flash measuring can be carried out in all diffuser settings (incident or reflected light measuring modes). Furthermore, flashes can be measured with or without a sync cord (cord/noncord). If a sync cord is used, the flash is automatically triggered and measured with the measuring button . [. . . ] However, the Schwarzschild effect often has the same effect as less exposure. In order to obtain experience, take your first shots with unaltered values that are given by the Starlite. Schwarzschild effect Shots with little light require particularly long exposure times. For all brands of film, what is known as the Schwarzschild effect occurs here: The measured times must be increased for the shot to avoid under-exposure. [. . . ]
