I exposed several still life images today with the Harman 4x5 FB Direct Positive paper. I rate the paper at ISO1.6 and preflash. Development is in fresh developer mixed from concentrate at 1:15 at 68f. Camera used was Anniversary Speed Graphic with 150mm binocular lens stopped down to 20mm aperture (about F/11 at the bellows extension). The lighting was indirect north-facing daylight.
