There's been a lot on here about how ECN-2 film should not be developed in C41 chemistry. I generally mix my own variant of ECN-2 developer using the correct CD3 developing agent. I know CD4 should not be used. The only place I am aware of that sells CD3 in small quantities is Artcraft, and CD3 is considerably more expensive than CD4. So my questions: Anyone know anywhere else to get CD3 in small quantities? Can CD2 be used in place of CD3? (Artcraft sells it for the same price as CD4). Thanks!
