I'll have to do another set of prints to do the dmax readings as one of the print got shipped off. I can do this though, just give us some time. The paper was Stonehenge.
Hi Klainmeister, If you could do a set of dmax readings and include a step wedge like in the photo attached that would help us to see how effective fumed silca/alumina is and how it might be changing the entire tonal range compared to a print that is uncoated on the same paper. I have stock of silica and alumina but just have not had a chance to really experiment with it. Thanks
