How they work together

HC-110
Fine grain, high acutance, full film speed, normal contrast. Full-scale with good shadow detail.
Bergger Pancro 400
French double-emulsion film with two silver halide layers of different grain sizes. Wide tonal range from very fine to drawn grain depending on developer choice. Presoak recommended.
