Filter Factors
When a filter is used, multiply the unfiltered exposure by the filter factor for the particular filter shown
below. Since lighting conditions vary, these factors are only approximate:
Orientation Light Source Kodak Wratten Gelatin Filter
No. 8 No. 15 No. 47B No. 58
To the emulsion Pulsed-Xenon 2.0 3.5 12.0 4.0
Quartz-Halogen 1.5 2.5 40.0 3.5
NOTE: It is recommended that the manufacturer of the pulsed-xenon or quartz-halogen lamps be
consulted for safety information pertaining to ultraviolet radiation and ventilation requirements due to
ozone generation.
