Here's an interesting tidbit concerning film curve vs paper curve. In formulating his DI-13 developer for TMax 100, Phil Davis sought to create a D Log-H curve that was slightly flatter in the midtones (~Zones IV-VI) and steeper in both the shadows and highlights. The idea there was an attempt to counteract/offset some of the compression of highlights and shadows in the curve of the printing paper, rather than compounding the compression.
