Well, yes and no. You still have to expose properly. The slight diffuse flare ( there's very little with a masked compendium and only two internal surfaces) will help get the film off the toe of the curve, thus opening up the shadows a bit. It's one of the reasons I use the lenses, that and the smooth tonality.
I get good shadow detail with the set of modern coated lenses which I use on 4x5, too. And then there's the possibilty that it's something to do with my monitor, or the contrast range the poster chose.
But if that's what is on the negatives, the shadows are underexposed, and the contrast range of the scene is such that it isn't neccesary.
That's what I meant. I gain effective film speed increase of about half a stop with older lenses, compared to newer ones.
