Some years ago I did tests with Tri-X in various developers and different
ISO ratings. TriX @ISO200 in Microdol X 1+3 could manage >12 stops, in D76
1+1 at ISO 400 <10stops. I'm not talking about range you could only measure
with a densitometer, this was a real-world image from which I made prints.

My test image was a kitchen, with a moderately sunlit snow scene visible
through the window.
