Re: was Miracle size for gum now tonal range

A glance at a glancing response to the above suggests that this point was imperfectly understood by some readers, and perhaps imperfectly communicated. Here, I was responding to Marek's argument (below) that the more you increase the dichromate the more hardening you get, which is true, but only to the point that the layer is completely hardened. When I asked for clarification about what he thinks you get with increased dichromate, I meant *beyond* that point. Up to that point, of couse, the answer is clear: with more dichromate you get more speed and more steps printed. But after that point I wasn't sure what you get; I don't think you get anything, but I was trying to understand what Marek thinks you would get beyond that point.
That was my point there, and as I said, perhaps imperfectly communicated. But no, I certainly wasn't arguing that in general, within the range of normal practice, more dichromate doesn't get you definite benefits; after all, I use saturated ammonium dichromate precisely *because* I have determined that for me, the combination of speed and longer tonal range suits my needs exactly. But I wasn't sure what it was that Marek was arguing and was asking questions to try to help me parse his argument.
