¥Set the film speed at ISO 100. Since the amount of light reflected onto subjects from surrounding surfaces will differ with the conditions, refer to the flash unit instructions.

Daylight Photoflood/Photo-Reflector Lamps

¥Daylight-type photoflood or photo-reflector lamp output tends to be lower than that indicated by an exposure meter, so it is advisable to compensate for this by increasing exposure time or the lens opening. Whenever possible, test exposures are recommended.

¥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 best results, the following combinations of color compensating filters are recommended. However, for exacting work, test exposures are advisable.

		Fluorescent			High-intensity
					Discharge
Lamp Type	Day-	Cool	White	Warm	Deluxe	Clear
	light	White		White	White	Mer-
	(D)	(CW)	(W)	(WW)	Mercury	cury

Corrections**

*Fuji Color Compensating Filters (or Kodack CC Filters)

**Exposure Correction values include filter exposure factors. These values are added to unfiltered exposure meter read- ings. "+" followed by number = 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 exposures 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

Fuji Light Balancing Filter LBB-12 (or Kodak No. 80A) is

recommended along with a 2 lens stop increase, when using 3200 K tungsten lighting.

5.LIGHTING EQUIPMENT

The conditions of umbrellas, reflectors, diffusers and like devices, may influence photographic light quality. Periodically check lighting equipment for deterioration.

6.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.

Exposure Time (sec)	1/4000 - 2	4	16	64
Exposure Corrections*	Unnecessary	+1/3	+2/3	+1

* "+" followed by number = 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.

7.FILM HANDLING

¥Expose film before the expiration date indicated on the film package and process promptly after expo- sure.

¥When loading and unloading roll film, avoid direct sunlight. If there is no shade, turning one's back toward the sun will shade the film.

¥Camera-loaded film should be exposed and pro- cessed immediately.

¥X-ray equipment, used to inspect carry-on baggage at airport terminals, can cause film fogging. Re- peated inspections increase this possibility, so both exposed and unexposed films should be re- moved for manual inspection.

¥Film fogging may occur near X-ray equipment used in hospitals, factories, laboratories and other loca- tions. Always keep film away from possible sources of radiation.

8.FILM STORAGE

Unprocessed Film

¥Storing exposed or unexposed film under high temperature and humidity conditions will cause adverse speed, color balance and physical prop- erty changes. Store film under the following con- ditions.

	¼ Ordinary Storage: Protect from heat.
	¼ Long-term Storage: Below 0°C (32°F)
