Response to Acros & HP5+

Delta 100 will (at 0.09>B+F) just make its published EI:100. It is blazingly sharp, particularly when developed in PMK. The extra 2/3 stop becomes very important for hand-held work. Using 4X5 or larger, I find that HP-5+ is a terrific film. It has just about a ruler flat 'curve' and at larger negative sizes, grain is not much of an issue. And unlike Kodak, Ilford films do not gain contrast with the long exposures required for reciprocity corrections. Even on a tripod, 64 speed is an issue because the required long exposures make photographing even in mild wind conditions quite difficult. I'd be much more interested in a 'new' film, if it were actually advancing the technology rather than copying an existing formula.
