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 vari-

ous factors (differences in equipment, amount of

use, etc.) should be taken into consideration. Test

exposures are recommended.

 If shutter speeds slower than 1/60 second are

used, light from non-flash sources, such as room

lighting, may cause color imbalances. Make test

exposures.

 The use of a flash meter is advisable, but the follow-

ing formula can also be used to obtain satisfactory

lens opening.

 Set the film speed at ISO 400. Since the amount of

light reflected onto subjects 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 an ex-

posure meter, so it is advisable to compensate for

this by increasing exposure time or the lens open-

ing. Whenever possible, test exposures are recom-

mended.

 Other factors requiring consideration when deter-

mining the exposure time, are lamp configuration,

use duration and line voltage, as they may affect

lamp output and color balance.

Fluorescent Lamps & High-Intensity Discharge

Lamps

 For the best results, the following combinations of

color compensating filters are recommended.

However, for exacting work, test exposures are ad-

visable.

* Fuji Color Compensating Filters (or Wratten CC Filters)

** Exposure correction values include filter exposure factors.

These values are added to unfiltered exposure meter read-

ings. A "+" followed by a number indicates the required in-

crease in lens opening.

 When the fluorescent lamp characteristics are un-

known, to obtain generally acceptable results, use

a 30M compensating filter and open the lens one

stop (+1).

NOTE Different compensation may be required according

to special lamp types and length of use, so test ex-

posures are recommended, whenever possible.

 Shutter speeds of 1/125 second for high-intensity

discharge lamps and 1/30 second or larger, for

fluorescent lamps, will avoid AC power-induced

changes in brightness and color being recorded on

the film.

Tungsten Lamps

A Fuji Light Balancing Filter LBB-12 (or Wratten filter No.

80A) is recommended along with a 2-stop increase in

lens opening, when using 3200 K tungsten lighting. In

the case of cameras with TTL metering, there is no need

for additional exposure compensation.

6. LIGHTING EQUIPMENT

The conditions of umbrellas, reflectors, diffusers and

like devices, could influence photographic light quality.

Periodically check lighting equipment for deterioration.

7. LONG EXPOSURE COMPENSATION

No exposure or color balance compensation is required

for exposures within a 1/4000 to 2 second shutter speed

range. However, for exposures of 4 seconds or longer,

provide the compensations indicated below.

* A "+" followed by a number indicates the required increase in

lens opening.

Except for special effects, the normal intensity ratio for

main-to-fill subject lighting should remain within 1:4

limits.

8. FILM HANDLING

 Expose film before the expiration date indicated on

the film package and process as soon as possible

after exposure.

 Expose camera-loaded film before the expiration

date and process immediately.

 The following cartridge markings indicate the cur-

rent status of the film. Make sure to verify the film's

status before loading the cartridge.
