Just tried the Art300 for the first time and though my prints are still in the wash, all I can say is WOW!
I was totally blown away by the way it handles blacks. I am so used to using the chamois and the creaminess of it, but blacks weren't it's strong point. The Art300's tonal range is spectacular and incredibly rich... Yes, this is the richest paper I have held in my hands.
I had already made up my mind to use the Kentmere Bromide for this project because of the cold blacks until I printed this just on chance since I just got it. Will see how much it lightens when dry.... but man, is this paper sweet. I will definitely be using a lot of it.
And, thank you, Thomas for the recommend!
