I'm now showing about a 5% reduction in midtone grain with Acros 100 and at least that much with Agfapan 25, where in some areas it looks more like a 9% improvement. These numbers are the change in the Standard Deviation measure of featureless areas of the negatives. I used 2 Kodak diffusion sheets taped onto the top of the Nikon 8000 glass carrier, about 1/8 inch above the glass. So, it's not dramatic, but I am seeing some positive effects from the diffusion.
