Digital BW, The Print

I like to use the overcoat because it erases all gloss differential between the image and the paper - and that adds realism to the print for being a photograph as we once recalled. I don't like how ABW looks on a sheet. It sits on it. I prefer there be no difference between ink and paper if its going to be glossy. That's how a darkroom print looks and that's how I designed use of Peizography Gloss Optimizer - as a total sheet overcoat. The ABWs I saw on silver rag at SPE looked a bit inkjetty to me. Just an opinion.

But, if you're asking whether my shades 4&5 need GO to appear glossy. No they do not.
