TECHNICOLOR AND OTHER METHODS 211 



to picture their beauty in all their natural color is a 

 wonderful achievement. 



I know of no field that offers more opportunity for 

 research work and chance for new discoveries than 

 picturing in natural color subjects illuminated with 

 polarized light. The difficulties in getting correct 

 exposures with polarized light are so increased over 

 those of other methods that the percentage of failure 

 is bound to be very high. 



Just what polarized light, ultra violet, and other 

 forms will do is still an open question; one of the 

 new tools with which to experiment, "To play with," 

 as the research workers for the General Electric 

 Company at Schenectady say when a new invention 

 is turned over to them to find out its uses. 



In closing this chapter I strongly advise using a 

 method I have found successful for artificially lighted 

 subjects. 



Make test exposures in normal and lapse-time 

 close up and through the microscope, of a red, then 

 a blue and then a yellow subject, making frontage 

 enough of each to get a good idea when the result 

 is projected. Make each subject three times, first with 

 one third less time than you think is right, then 

 your judgment on the correct time, then a third 

 more, and for each subject measure the light with a 

 very sensitive light meter, keeping careful records
