Hello Thomas, this sound new to me. What Tanol is? I see a good acutance but I don't know how much of it is coming from the developer and how much from the Unsharpen mask of your scanner.
Giuliano, Tanol is a product made by Moersch-Photochemie (take a look at google to find the homepage), a stain developer that really works fine with many films. The negatives are acurate, the rest may depend on my scanner. Thanks for looking, bye - Thomas
