Technical specifications Your LUNA-STAR F is an exposure meter with digital display from GOSSEN. It measures continuous light and flash, and it covers a wide measuring range with great accuracy. 4www.b ut kus .org A wealth of knowledge in the area of light metering, based on many decades of experience in the manufacture of exposure meters, is now being made available to the user, in the simplest manner possible, due to microprocessor technology.

Measurements cease to be possible if the display only indicates "BAT". The battery must be immediately replaced. To change the battery open the battery compartment of the LUNA-STAR F. Remove the exhausted battery. Clip the contacts onto the new battery and insert in the battery compartment. Push back the battery compartment cover.

This means that inherently brighter subjects are not precisely measured and therefore rendered darker. 4www. but ku s.org This mode is also used to measure the subject contrast which is displayed by the LUNA-STAR F on its analog scale.

Set the desired ISO value with the values buttons. (Display: left DIN value; right ASA value) Once the film speed has been set it is transferred to the memory of the LUNA-STAR F when the meter is adjusted to any operating function, and it remains visible at the top on the right-hand side of the digital display.

d) CINE speed (frames per second) o Select "t" with the functions buttons. o Select the desired speed (f.p.s.) with the values buttons. For this purpose go beyond 1/8000ths. After approx. 1 second the meter switches over to CINE speeds. The symbol appears on the display.

The digital shutter speed display disappears, to be replaced by information on the number of flashes that have to be fired for the desired f-stop (e.g. F4 = 4 flashes). The LUNA-STAR F will calculate up to a maximum of 10 flash sequences. 4www.butkus.org...

Read-out Outside the Display Range o If the symbol " U " or "n"', appears on the right or left digital display it means that a reading has been taken, but its display is outside the meter's display range. o With " "...

Important Remarks Concerning "Correction Values" The LUNA-STAR F is a precision meter calibrated with great accuracy to provide you with exact exposure data. Should you still not be satisfied with the results, then you should remember that there are other...
Now select from the processed pictures the one you consider to be optimal and compare its settings with the meter readings. If you find that you prefer exposures that were taken with settings that differ from those supplied by the meter, then this value can be programmed into your LUNA-STAR F.

Your Gossen LUNA-STAR F is a valuable precision instrument made with great care and accurately calibrated. It deserves your good care! Measuring comparisons of your LUNA-STAR F with similar or other types of exposure meters cannot be made properly without special laboratory equipment (optical bench). Do not attempt to open or repair your LUNA- STAR F.

+5 Measuring Range Extension for Reflected Light Measurement This attachment permits the measuring range of the LUNA-STAR F to be extended by 5 steps when measuring the light reflected by the subject. In this manner even very bright light will be measured perfectly.
