That was certainly true of Crawley's Acutol S with 35mm film, I tried if before I bought my own MF camera and it was too graphic, but people said at the time it was excellent with MF or larger negatives.

It's worth high-lighting that the good (reputable) photograpers who advocated these developer or stand development and/or other techniques to enhance acutance are using predominantly LF or ULF and they contact prints.

I had this discussion with Ralph Lambrecht 18 months ago and we realised no one had thought abot the importance of acutance and format
