****A “+” followed by a number indicates the required increase in lens opening.

Electronic Flash

•Electronic flash produces light similar to daylight, so filters are not needed. However, the possibility of undesirable effects on color balance, due to various factors (differences in equipment, use duration, etc.) should be taken into consideration. Test exposures are recommended.

•The use of a flash meter is advisable, but the follow- ing formula can also be used to obtain a satisfactory lens opening.

•Set the film speed at ISO 100. Since the amount of light reflected onto the subject from surrounding sur- faces will differ with the conditions, refer to the flash unit instructions.

Daylight Photoflood / Photo-Reflector Lamps

•Daylight-type photoflood or photo-reflector lamp output may be lower than that indicated by the exposure meter. It is recommended to compensate for the difference by increasing the exposure time by lowering the shutter speed or by increasing the lens opening. Whenever possible, test exposures are recommended.

•Other factors that should be considered when deter- mining the exposure settings are lamp configuration, length of time used and line voltage, as they may affect lamp output and color balance.

Fluorescent Lamps

•The use of the following combinations of color com- pensating filters is advisable when photographing under fluorescent lighting.

•For exacting work, however, test exposures are rec- ommended because lamp brand and age may affect light output and color balance.

*Wratten Color Compensating Filters or Fuji Color Compensating Filters are recommended.

NOTE: No. 80C is a Wratten Color Conversion Filter.

**Exposure correction values when using a filter relative to unfil- tered exposure results. A “+” followed by a number indicates the required increase in lens opening.

NOTES

•Use a shutter speed slower than 1/30 second.

•For shutter speeds of 2 minutes or more, exposure adjustments will be necessary to compensate for reciprocity law failure.

Tungsten Lamps

•A Wratten Filter No.80A (or Fuji Light Balancing Filter LBB-12) is required when using 3200K tungsten light- ing. A 1 2/3-stop larger lens opening is also required.

•If household tungsten lighting (room lamps, etc.) constitutes the main source of illumination, in addi- tion to the above filter a Wratten Filter No.82A (or Fuji Light Balancing Filter LBB-2) is required, plus an ap- erture increase of 1/3 stop (total 2 stops).

Mixed Light Sources

Under mixed light conditions, the basic filter configura- tion should suit the main light source. In the case of cameras with TTL metering, there is no need for addi- tional exposure compensation for any CC filter(s) used.

6.LONG AND MULTIPLE EXPOSURE COMPENSATION

No exposure correction or color balance compensation is required for exposures within a shutter speed range of 1/4000 second to 1 minute. However, for exposures of 2 minutes or longer, ‘reciprocity law failure’-related color balance and exposure compensations are required.

Multiple Exposures

No exposure correction or color balance compensation is required for up to four consecutive multiple exposures using an electronic flash. In the case of eight consecu- tive multiple exposures, a 2.5G color compensating filter is required with a 1/3- stop larger lens opening.
