[. . . ] ­ With the AVR measuring button you can measure up to 8 further contrast spots. The single measuring values are displayed on the analogue scale (identical measuring values are only displayed once, but are taken into consideration when the average is calculated). After each measurement with , the average of all previous measuring values is displayed. The average AVR appears on the left digital display: f or EV with f-numbers in 1/10 increments and flashing on the analogue scale, rounded to 1/2 stop increments. In the middle of the display, the number of measurements M is displayed (4 measurements in the example). Incident light with flat or spherical diffuser Correspondingly, you can determine the average value of the illumination of the various lights with the above mentioned procedure. To do this, you can measure for example your main, fill-in and background light individually in the studio. AUTOTEK Foto- und Lichtmeßtechnik 19 5. 6 Selecting the exposure time values In addition to the standard full time values, also half time values (1/2 TV) can be set at some cameras. 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 AUTOTEK 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 Starlite calculates on the basis of the measurement already taken the number of flashes required for the desired f-stop. The digital display of the time disappears and the number of flashes required is indicated, (e. g. of 9 flash sequences. 24 AUTOTEK Foto- und Lichtmeßtechnik 6. 4 Average value ­ Take first measurement using measuring button ­ Measure up to a further 8 flashes using the average value measuring button . The individual measurements are shown on the analogue scale (identical values are only displayed once, but are taken into account in the calculation of the average value). After each measurement with , the average value of all previous measurements is always displayed. The average value AVR is shown in the digital display: at the left with fine adjustment in 1/10 stop increments and shown as a flashing mark in the analogue scale, rounded to the nearest 1/2 f-stop. However, the ambient light portion is not indicated. In the centre of the display, the number of measurements M taken is indicated (in the example 4 measurements). AUTOTEK Foto- und Lichtmeßtechnik 25 7 7. 1 Taking a measuring outside the measuring range ­ display range Taking a measurement outside the display range If the symbol uu oder nn appears in the right or left digital display, the measurement has been taken but the result is outside the display range. ­ Use setting wheel to move into the display range 7. 2 Taking a measurement outside the measuring range ­ There is no usable measuring result outside the measuring range of the Starlite. ­ If it is too dark or too bright during the measurement, Err (= Error) appears in the left digital display. 26 AUTOTEK Foto- und Lichtmeßtechnik 8 Setting and measuring correction values and extension factors Example: ­3. 1 stops correspond to the extension factor 8. 6. For corrections which shorten the exposure, only the left display appears as EV difference in stop increments. By pressing one of the function buttons ( or ) the correction value is stored in the memory of the Starlite. [. . . ] In both cases the analogue display shows the contrast. 34 AUTOTEK Foto- und Lichtmeßtechnik Negative film If the difference between important bright and dark areas does not exceed two stops (EV) between important bright and dark areas are not exceeded, each value in between these values could be used as the setting value; for greater demands the average value is more suitable. For negatives, the smallest density that can copy is important - thus, you should use more exposure rather than too little. Color reversal film In comparison to a negative film, a color reversal film can deal with greater subject contrast, but offers far less scope for usable exposure. Measuring the subject contrast is the basis for the decision as to whether the subject can be reproduced realistically. [. . . ]
