Hi Christina,
I can't comment on the Future since I have no experience with it. ;-) However, I know that
cyanotype does fade in bright sun, BUT, it will also revert if left in the dark. Some say
moisture is what makes it revert. I don't know. Nor am I sure if it will revert completely to
its former state.
