I finally had the chance to try the Ilford 300 Art paper, and it is really wonderful. I tried it with both ilford warmtone developer as well as the standard house developer in the rental darkroom that I use, and I can't say I saw an incredible difference. One thing I did notice, is that it seems to have more contrast at any given grade of filtration. That is, while I usually tend to print using grade 3 setting on the Ilford variable contrast head, I found that I was printing using the grade 1 settings or the highlights would be blank. I guess I could have pre-flashed, but I did get dense blacks even at that setting(surprisingly). One other caveat is that the paper does get very fragile if you leave it in the wash too long. My usual M.O. is to leave prints in the water tray until my session is over, then process them through PermaWash and two 10-15 minute baths in running water for standard Ilford FB. With the Art, it is important to keep moving along the line as per Ilford directions lest the paper start breaking down. Also, it dries wonderfully flat on a screen in a relatively short time. This is a fantastic paper for specific images as it gives an almost "sketch like" quality to the print. Thanks -and congratulations- to Ilford for developing it. Regards, Michael
