Excessively high or low subject color temperatures may
require the following filter
additions and exposure corrections.
The foregoing settings are for 2 hours after sunrise and 2
hours before sunset.
Provide lens opening 1/2 stop smaller during the summer
and 1/2 stop larger during the winter.
Excessively bright (or dark) or backlit subjects may require
plus or minus 1 stop lens opening adjustments.
Daylight
Under daylight conditions, color balancing filters are not
necessary, but the following exposure conditions may
require the indicated filters.
NOTES
Fair weather open shade and shaded
landscapes.
Bright distant scenes, snow land-
scapes, seaside scenes, aerial
scenes and open landscapes.

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
The use of the following combinations of color com-
pensating filters is advisable when photographing
under fluorescent lighting.
For exacting work, however, test exposures are rec-
ommended because lamp make and age may af-
fect light output and color balance.

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 various
factors (differences in equipment, amount of use,
etc.) should be taken into consideration and test ex-
posure made.
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 100. Since the amount of
light reflected onto the subject from surrounding
surfaces will differ with the conditions, refer to flash
unit instructions.

** Exposure correction values include filter exposure factors.
These values are added to unfiltered exposure meter readings.

Use 1/30 or slower shutter speeds.
For shutter speeds longer than 128 seconds, exposure ad-
justments will be necessary to compensate for reciprocity
failure.

LBB-12) is recommended along with a 1

stop increase, when using 3200K tungsten lighting.
If household tungsten lighting (room lamps, etc.)
constitutes the main source of illumination, in addi-
tion to the above filter a Kodak filter No.82A (or Fuji
Light Balancing Filter LBB-2) is required, plus an
aperture increase of 1/3 stop (total 2 stops).
Mixed Light Lamps
Under mixed light conditions, derive the basic filter con-
figuration to suit the main light source.

5. LONG AND MULTIPLE EXPOSURE
COMPENSATION
No exposure correction or color balance compensation
is required for exposures within a 1/4000 to 128 seconds
shutter speed range. However, for exposures of 128
seconds or longer, reciprocity-failure related color bal-
ance and exposure compensations are required.
