Electronic Flash
Electronic flash produces light similar to daylight, so
filters are not normally needed. However, the possi-
bility of undesirable effects on color balance, due to
various factors (differences in equipment, amount of
use, 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.

Electronic Flash-to-Subject Distance
(meters)
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 out-
put may be lower than that indicated by an exposure
meter, so it is advisable to compensate for this by in-
creasing exposure time or the lens opening. Whenever
possible, test exposures are recommended.
Other factors requiring consideration when determin-
ing the exposure time are lamp configuration, use du-
ration 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 CC Filters) are
recommended.
** Exposure correction values include filter exposure factors.
These values are added to normal exposure meter readings.
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 64 seconds or more, expo-
sure adjustments will be necessary to compensate
for reciprocity-related failure.
Tungsten Lamps
A Wratten Filter No.80A (or Fuji Light Balancing Filter
LBB-12) is required when using 3200K tungsten
lighting. A 1

-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.
