Tungsten Lamps
•
Photographic tungsten lamps should be used at their
specified voltages because any deviation from the
correct voltage affects the color temperature. As light
output and color temperature vary with manufacturer,
total time the lamp has been used, line voltage,
reflector and diffuser, etc. employed, test exposures
are recommended.
•
Since household tungsten lamps have generally low
color temperatures (around 2700K), No. 82A or LBB-
2 light-balancing filters should be used if these lamps
constitute the main light source.
Daylight
Daylight and general electronic flash exposures require
the compensations listed in the above table. Exposures
made under bright sun or clear blue sky conditions,
where the color temperature is higher, will require the
use of No. 85B + No. 81A or LBA-16 filters. Low color
temperatures will necessitate the use of No. 85B or LBA-
12 + LBA-2 filter.
Fluorescent Lamps
Even with fluorescent lamps of the same type and
manufacturer, there will be differences in light quality
relative to use duration, reflector, diffuser and lamp fix-
ture types. Test exposures, therefore, should be made
whenever possible.
Mixed Light Sources
Exposures made under mixed light sources (especially
a mixture of daylight and tungsten light) are not recom-
mended. If these conditions are unavoidable, light com-
pensation filtration should be provided relative to the
dominant light source.
Other Light Sources
With metal-halide lamps, mercury-vapor lamps and fluo-
rescent lamps other than those listed in the above table,
provide initial test exposures to determine the best
filter(s) to use and proper exposure time.
5. LONG EXPOSURE COMPENSATION
Reciprocity compensation is not required if exposure
times remain within the 1/15 to 64 second range. How-
ever, in cases where over 64 seconds are necessary,
exposure compensation as shown in the following table
should be used.
* "+" followed by number = required increase in lens opening.
6. EXPOSURE PRECAUTIONS
With artificial light, such as electronic flash, photoflood,
fluorescent, tungsten, mercury vapor, etc., the lamp out-
put and color temperature may be affected by such fac-
tors as make, age of equipment and line voltage. Reflec-
tors and diffusers can also influence light intensity and
color temperature.
7. FILM HANDLING
•
Expose film before the expiration date indicated on
the film package and process as soon as possible
after exposure.
•
When loading and unloading roll film, avoid direct
sunlight. If there is no shade, shield the film from
the sun with your body.
•
Handle sheet film in total darkness. Avoid touching
emulsion surface. (The use of a safelight will cause
fogging.)
