User manual MINOLTA FLASH METER III PART 2

[. . . ] With the latitude display function, the Flash Meter VI can simultaneously display the results of both incident light measurement and spot light measurement. It provides a clear and simple graphical decision process for determining the exposure suited to the nature of the photograph. With the analyze scale, you can determine the proportion of flash light and ambient light in a single flash light measurement. The Flash Meter VI provides a memory function capable of storing up to 10 measured values; an averaging function that calculates an average exposure from stored measurement data; and a brightness difference function that displays deviation from the standard exposure. [. . . ] The reading is also displayed on the analog scale. The proportion of flash light illuminating the composition is shown on the analyze scale. Pressing the CLR button clears the measurement data. If no flash is connected to the sync terminal, or if the flash does not fire normally because it is not fully charged, the meter cannot take a flash light measurement. Before starting measurement, make sure that the flash is connected to the sync terminal and the flash has been fully charged. The f-number corresponding to the shutter speed set in step 4 is displayed on the digital readout as well as on the analog scale with a pointer ( ). The proportion of flash light illuminating the composition is shown on the analyze scale. Example: The display shows a reading of F8. 0 + 0. 9 stops, and the proportion of ambient light to flash light is about 1:1. E28 E29 Basic Operation Basic Operation When measuring flash light using a sync cord (CORD mode), the flash may fail to fire (e. g. if the trigger voltage of the flash is too low). In this case, take a reading without sync firing the flash (NON CORD mode). If the f-number reading is outside the meter's display range, "FNo. " blinks and the display shows either "­ O ­ " (over-range error) or "­ U ­" (under-range error). At the same time, the over-range/under-range error indicator ( or ) appears on the analog scale. If the f-number reading exceeds or falls below the meter's measuring range, the display shows "E. o. " (over-range error) or "E. u. " (under-range error). E30 E31 Basic Operation Basic Operation 2. At the same time, the over-range/under-range error indicator ( or ) appears on the analog scale. E34 If the f-number reading exceeds or falls below the meter's measuring range, the display shows "E. o. " (over-range error) or "E. u. " (under-range error). E35 Basic Operation Basic Operation Using the up/down dial to change the shutter speed to 1/15, we can see how this change will affect the mix of ambient and flash light. The aperture has changed to F4. 03 and now, only one quadrant is lit up. This indicates that the proportion of flash light is now only 25% (ambient:flash ratio =3:1). A photograph taken under these conditions will be influenced more strongly by the tungsten light (orange) and less strongly by the flash light (white). Light Ratio Analyze function For flash light measurement, the Flash Meter VI uses a method of measuring flash light/ambient light separately. The proportion of ambient light and flash light to the total exposure is indicated on the quadrant analyze scale. How to read the flash/ambient light ratio : 0 ~ 16% :17 ~ 41% :42 ~ 58% :59 ~ 83% :84 ~ 100% Whenever you take a flash light reading, the analyze scale is displayed on the LCD data panel. After a reading, you can also do a simulation to see how changes to the shutter speed affect the proportions of ambient light and flash light. The analyze scale shows the proportion of flash light in the total exposure reading as one of five levels. On the other hand, increasing the shutter speed (within the range of sync) will have the opposite effect-photos will be more strongly influenced by flash light (white) than ambient light. Example of reading, display and simulation Assume that a tungsten lamp is used as the ambient light source. Reading of F2. 80 at a shutter speed of 1/60 sec. Two quadrants are lit up on the display, indicating that the proportion of flash light is approx. 50% (ambient:flash ratio =1:1). A photograph taken under these conditions will not be strongly influenced by either the tungsten light (orange) or the flash light (white). This simulation is based on controlling the ambient light by varying the shutter speed. [. . . ] Nothing particular Only the accessories shown above may be used with the Flash Meter VI. E74 E75 Handling Instructions 1) If the meter is used in the rain, at the seashore, or near a volcano, it may become rusty or corroded due to water or corrosive gas. In such situations, be careful to protect the meter as much as possible. 2) Do not subject the meter to shock or vibration. For protection, store the meter in its case when carrying it. [. . . ]
