+===== Characteristics =====
+X-Tol is said to give better shadow tonality and keep highlights down without blocking up. Appropriate for situations with direct-light [(cite:>[[https://www.photrio.com/forum/threads/xtol-vs-rodinal.120246#post-1593351]])].
 ===== Notes on usage =====
 ==== Dilutions ====
-Use a minimum of  xml concentrate per roll (120/135).
+Use a minimum of 100 ml concentrate per 80 sq inch (=645 cm² = 1 roll (120) = 4 sheets 4x5).
+  * 1+2 : 175ml + 350ml = 525ml
+  * 1+2 : 160ml + 320ml = 480ml
