I found some time to perform color rendition testing using J Lane Speed Plates. Metered at ASA 25, the rendition is similar to unsensitized plates but at a "more modern" speed. Drop a Yellow #2 aka K2 filter in front of the lens, add compensation time for the filter, and the orthochromatic response of the plate becomes evident.
The bottom images of the MacBeth chart were shot in the test conditions shown in each caption. Development time was per Pictoriographica's standard recommendation. Both plates were scanned at the same time with the same settings. The plate scans were cropped, and coupled to the color versions of the chart.
