> I thought the acutance issue pretty much disappeared with a 4x5 neg(posted 8780 days ago)No, not to me. For example, my prints from HP5+ negs look "sharper" than those from Delta 100 etc simply because there's that almost-invisible "toothiness" of the grain; the prints from the slower films are of course really sharper.
In the same way, an 8x10 from 4x5 HP5+ looks sharper than an 8x10 contact from 8x10 HP5+ although the contact is really sharper.
The differences are _much_ less apparent than smaller formats.
