Slow speed black and white films.

	Slow black and white film

	Film with ISO from 25-32 Film that is the sharpest, finest grained of all black-and-whites generally in use. Films that feature high contrast that can be fine-tuned in film processing. Capable of resolving more image detail than almost any camera or enlarging lens can reproduce. A really first-class camera lens should be able to resolve 100+11/mm shooting a high-contrast subject; slow black-and-white films developed in fine-grain chemistry can resolve 200+11/mm. If it's just so much resolution overkill, why bother with the slow films at all? It is the overkill capability that makes slow black-and-white films so useful. The reserve capacity of these films allows them to deliver excellent results in less-than-optimum lighting conditions. Most can deliver 200+11/mm shooting a high-contrast subject and are still able to resolve 90-100+11/mm in low contrast�more than enough to record every line of resolution a good lens is able to transmit to the film. Additionally, it should be obvious by now that everything in photography involves tradeoffs. For slow-speed black-and-white films it has been speed for grain. Less speed�less grain. Improvements in grain and overall image technology have made ISO 100�speed film the new standard. However if you desire to produce exquisitely detailed, grainless enlargements larger than 11 x 14, you should master the use of one of the slow black-and-white emulsions. With care in the darkroom, you should be able to make all-but-grainless, super-detailed 24 x 30-inch or bigger prints.
