"Print" tone smoothness, resolution, grain size, and sharpness are all affected by film size.
A given film, say Delta 100, has a given resolution "per square inch" expressed as xxx line pairs per millimeter.
35mm film has roughly 1.5 square inches of area, the Hassy has about 5 square inches. So assuming both the Lieca and the Hassy have the same film inside, the Hassy negative can hold over three times as much data.
The Hassy negative can define a lot more points in the print.
It depends on the enlargement, but how is print tone smoothness affected by format size?
