Henry, unlike HP5+, Delta 100, the old Delta 400 and TMX, all of which usually have a straight-line curve shape _way_ out there, the curves I'm getting with new Delta 400 show a pretty strong shoulder above about Zone IX or so; I'm wondering if what you're seeing isn't excess density but true blocking. By blocking I mean that contrast goes pretty low, and without contrast there isn't detail.(posted 8424 days ago)
