Electronic Flash
Use the guide number in the following table as a starting
point for your equipment. Select the unit output closest to the
number given by your flash manufacturer, then find the
guide number for metres or feet.
To determine the lens opening, divide the guide number
by the flash-to-subject distance. If negatives are consistently
too dense (overexposed), use a higher guide number; if they
are too thin (underexposed), use a lower number.
Fluorescent and High-Intensity Discharge
Lamps
Use the color-compensating filters and exposure adjustments
in the following tables as starting points to expose this film
under fluorescent or high-intensity discharge lamps. For
critical applications, make a series of test exposures under
your actual conditions.
To avoid the brightness and color variations that occur
during a single alternating-current cycle, use exposure
times of 1/60 second or longer with fluorescent lamps; with
high-intensity discharge lamps, use exposure times of
1/125 second or longer.

Note: When you don’t know the type of fluorescent lamps,
try a 10C + 20M filter combination and increase exposure by
2
⁄
3
stop; color rendition will probably be less than optimum.
Note: Some primary color filters were used in the previous
tables to reduce the number of filters and/or to keep the
exposure adjustment to a minimum. Red filters were
substituted for equivalent filtration in magenta and yellow.
Blue filters were substituted for equivalent filtration in cyan
and magenta.
Adjustments for Long and Short Exposures
No filter corrections or exposure compensation is required
for exposures from 1/10,000 second to 10 seconds.
PROCESSING
Process this film in KODAK FLEXICOLOR Chemicals for
Process C-41.
JUDGING NEGATIVE EXPOSURE
You can check the exposure level with a suitable electronic
densitometer equipped with a filter such as a KODAK
WRATTEN Gelatin Filter No. 92 or the red filter for
Status M densitometry. Depending on the subject and the
light source used for exposure, a normally exposed and
processed color negative measured through the red filter
should have the approximate densities listed below.
Because of the extreme range in skin color, use these red
density values for a normally lighted forehead only as a
guide. For best results, use a KODAK Gray Card (gray side).
