Let us know how you come along making photoresist at home :)

No seriously, I think the closest you'll get to making photoresists at home 
is to go through some old photography books and learn how they used to make 
before the days of organic synthesis. I recall gelatin and silver nitrate 
as being some of the ingredients they use to use.
