The problem with Anchell is that he misinterprets a lot of information. I have his cookbooks, and what he says about cubic v. tabular grains is not exactly sound science, even though he has a lot of otherwise useful information. Prakel makes the same mistake as Efke: TXP is a modern, thin-emulsion film. Not a thick-emulsion film. One of the reasons why silver amounts went down was increased efficiency of emulsions, not just cheapness.
