2 KODAK ULTRA MAX 400 Film • E-7023
Electronic Flash:
Use the appropriate guide number in the table below 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 feet or metres.
To determine the lens opening, divide the guide number
by the flash-to-subject distance. If negatives are too dark
(overexposed), use a higher guide number; if they are too
light (underexposed), use a lower number.

BCPS = beam candlepower seconds

Fluorescent and High-Intensity Discharge Lights
For best results without special printing, use the
color-correction filters in the table below as starting points
when you expose these films under fluorescent and
high-intensity discharge lamps. Use exposure times of
1/60 second or longer to avoid the brightness and color
variations that occur during a single alternating-current
cycle.
Though this film is tolerant of mixed-lighting situations,
for best color results under uniform fluorescent or
high-intensity discharge sources, use the exposure and
filter recommendations given below. These
recommendations are starting points.
Actual filtration may vary between lamps and lamp
manufacturers. Depending on the specific source,
additional filtration or special printing may be required to
achieve best results.
Note: When you do not know the type of fluorescent
lamps, try a 10C + 20M filter combination and increase
exposure by
2
⁄
3
stop; color rendition may be less than
optimum.
Note: Some primary color filters were used in the tables
above 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
You do not need to make any exposure or filter adjustments
for exposure times of 1/10,000 second to 1 second.
Exposures longer than 1 second may require compensation
and filtration.
