Comments:  TXP 320 exposed E.I. 200 using an incident light meter.  3 minute water presoak @ 70 degrees.  60 seconds agitation for first minute and then 10 seconds every minute.  I use a Paterson large tank that holds 5 reels of 120/220 film.  I load the bottom two reels with 220 film, then put three empty reels on top.  I use 40 ml of Rodinal and 2 liters of water for two 220 films, as a one shot developer.
