Good Evening Shootar401,

According to Kodak Professional Black-and-WhiteFilms, December, 1976 date, the speed is 100 under White-Flame Are of Pulsed-Xenon Arc, but only 80 under Tungsten and Quartz Iodine lighting. The recommendation for continuous agitation development is 4 minutes with D-ll for high contrast and 2 minutes with D-8 for maximum contrast. I will supply filter information should you need it.
