Hi Mr. "127" (btw, whatever happened to 000-126? We all know about 007)

I'm not that tecnhical that I could plot this, so I need help intrepreting the graphs. Are you saying that for the first scan with EFKE 25 that the only light passed thru the filter is the small area under the red curve that crosses over the 3rd and 4th section of the graph? All other light is either blocked by the filter or is not rendered by the film?
