Hi everyone. I'm new here so I apologize if this topic has already been sufficiently covered. I couldn't find an appropriate thread. Anyway, I'm a film archivist and I've been dealing quite a bit lately with 35mm blow-up CRIs made from 16mm Ektachrome and ECO original which have started to (or completely) gone green in the blacks. I'm assuming that this is simply the result of the weakest dyes fading but it seems as though only my CRIs that include 35mm opticals such as fades or titles have started going green and the ones that were printed directly from the Ekta or ECO and had their effects (dissolves, etc) present in the AB original edits are perfectly fine, color wise. Does anyone have any info on this? And, more importantly, is there any hope for timing it out as I begin making new protection IPs?
