On 10-15-10 photo researcher had this to say;
Yes indeed Chris,I am researching the making of a color reversal film of the Kodachrome process type. This has actually been a project since I built the coating machine some years ago and has occupied most all of my time since!
Although I have worked in photo technology for fifty years,actually putting together a full color multi layer material is daunting.
Results so far are quite exciting but when it comes to combining all the elements
I know it will be tough.
Because of my past employment I have acquired a large number of the chemicals needed so I am lucky in this respect.
Soon I will start to communicate some of my work but I hope those interested will be patient, as sitting in front of a computer is not one of my favorite pastimes.
I'll reach out to him again and see if there is any new progress. I've offered to act as his "communications liason", but never heard anything back. It seems that his last statement is not an understatement!
