FUJIFILM DATA SHEET

FUJICOLOR SUPERIA X-TRA 800

* Fuji Color Compensating Filters (or Wratten CC Filters)

** Exposure correction values include filter exposure fac-

tors. These values are added to unfiltered exposure

meter readings. A "+" followed by a number indicates

the required increase 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 fluo-

rescent 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.

LIGHTING EQUIPMENT

The condition of umbrellas, reflectors, diffusers and like

devices, could influence photographic light quality. Peri-

odically check lighting equipment for deterioration.

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 lim-

its.

Exposure Corrections*

Daylight

Even when exposed under morning or evening twilight

conditions or when color temperatures are low, no spe-

cial filter use is needed as color balancing can be done

during printing.

Electronic Flash

Electronic flash produces light similar to daylight, so

filters are not needed. However, the possibility of un-

desirable effects on color balance, due to various

factors (differences in equipment, amount of use,

etc.) should be taken into consideration. Test expo-

sures 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 800. 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 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. When-

ever possible, test exposures are recommended.

Other factors requiring consideration when determin-

ing 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. How-

ever, for exacting work, test exposures are advisable.
