Roger, in 35mm (and possibly MF) Provia F is a better choice than Astia for scanning because of the finer grain. However, in LF (and especially 5x7 and up) grain is not an issue, and Astia has a wider exposure latitude than Provia F, whose characteristics are mid-way between Velvia and Astia. Otherwise, the article supports my thinking. I have decided on Astia for my next 500 LF exposures.
