When you have your finished transparencies, select the ones which, in your judgment, are “perfect” and compare them with your notes concerning exposure measurements, etc. Reciprocity Effect Film manufacturers base the “speed ratings” of photographic emulsions on average conditions of exposure times manusl illumination under which such emulsions are “normally” intended to be used.

Incident light illumination in footcandle. Then press the range selector 12 forward or backward. The Lunasix F was Gossen’s last professional meter with a mechanical moving needle display and the last without a microprocessor.
Photographic subjects are usually three-dimensional and they are illuminated from many different directions sun, sky, reflections from buildings, trees, ground, etc. Setting the film speed Look up the DIN or ASA Exposure Index of the film in use you will find it on the film box or film instruction sheet and turn the plexiglass film-speed setting disc 17 by the raised bars, until the DIN or ASA Index number is lined up against the triangular white marker in the respective window.
Ask your dealer for a demonstration! Deviations from correct exposure will produce trans parencies that are either too light or too dark; you may also get distortion of colours.

For black-and-white or colour negative films, this gsosen usually a darker lknasix which is to show details in the final print; for reversal colour slide or movie films, however, the lighter areas are usually favoured. The Personal Touch Do you really have to expose very critically every time? The ASA setting remains unchanged! See this link on a Wein Air replacement battery. Thus, under identical illumination, the indicator needle will be deflected less by dark objects than by bright ones.
And, normally, the exposure indicated in this manner is perfectly correct. Anything unusual which you – as attentive!
It is advisable to check the condition of the batteries from time to time, as follows: Incident Light Measurement see also pages 3 and 5 In this measuring method, your LUNASIX 3 “sees” only the light falling on that part of the scene which is facing the camera – in other words: Black-and-white films, generally, tolerate moderate deviations from normal conditions.
The LUNASIX 3 should not be considered a full-fledged footcandle meter because, strictly speaking, footcandles of illumination can be measured only be means of a flat interception screen. The built-in reflex finder with delineated “target” areas lets you pick out the exact portion to be measured.
When using colour correcting filters note the filter factor additionally. When I kept turning the zero screw clockwise, the needle swinged to the left, then it swing back to the right.

During the battery test, the indicator needle 14 should point to the red check mark Pointer needle with mechanical computer Sensor: In incident light measurement – from the subject towards the camera – the LUNASIX 3 measures all the light falling on that part of gowsen subject which faces the camera. Incident light measurement at a substitute spot of equal illumination is also convenient for many regular outdoor scenes.
In spite of mechanical display and “computer” dial, these meters are electronic as circuitry to store the light reading is necessary for flash measurement. Mallory PX 13 mercury batteries are available at most camera shops.
If there are extensive very bright or very dark areas in the scene, steer the LUNASIX 3 away from them and take the measurement from the “average” parts of the scene. Use a reversal colour film; select several “normal” scenes; take careful reflected and incident light measurements and shoot! For reflected light measurement, footcandle values cannot be given at all, since this method measures not the illumination but the brightness of the surface field luminance which can be expressed in footlamberts.
The small measuring areas permit very accurate, carefully aimed measurements for exposures with longer lenses, and selective readings of various parts of a scene or subject when normal lenses are used.
The dial has three separate rings:. The LUNASIX 3 is equipped with a spherical diffusing screen and thus achieves superior collection of the photographically effective illumination: With inaccessible subjects, take the incident light measurement at a substitute spot which receives the same illumination as the subject. Increasing or decreasing the ASA Degree by 1 is equivalent to one stop. The green and red ring indexes apply only for measurements with the Variable Angle “spot meter” attachment.
