<p>So, I am currently using a lightbox and D7000 with 55mm f3.5 Nikkor to "dupe" my slides and negatives. Works greats for slides. For the negatives, I'm wondering if I could lay a filter or two between the lightbox and the negative. Something like a Cyan 50 and Blue 50 maybe? Otherwise, I may be able to get a hold of an old color enlarger soon to use as the light source. I know the enlarger would probably work better, but just curious.</p>
<p>I'm shooting Kodak Portra 160, if that helps get a general idea of what I need to filter.</p>
