Hey guys, i've been experimenting with split filter printing but i need some advice. I understand the basic principles, use 2 different filters at least 2.5 grades apart, use one for part of the time and the other for the rest of the time. My question is how do you determine how much time you need for each filter. I've read that you expose with high contrast filter 1/3 of the time, and low contrast filter 2/3 of the time. Is there a better explanation of how to determine the allotted times? My professor demoed it but i was kind of zoned out.
Thanks
andrew
