Lumen print with a negative

I used a digital negative on acetate to try to make a lumen print. It was printed on long expired Fotospeed, double weight, semi matte lith paper which was very fast. The first print was made in about 5 minutes and actually had much higher contrast than the print that was exposed for three hours as the negative did not fully block the highlights.

The original before fixing has a beautiful metallic sheen to it. It is not visible in the scans, and unfortunately it can not be preserved as any light will fade the image before fixing.

The fixed version has a nice rust color.
