this is 2 tray : T1 is 50,60,600 ml of standard lith dev (pulled at 4 1/2 mins)
T2: is bromide, hydroxide ... bulk chems mixed in 2 liters water// USE WITH VENTILATION
T2: runs until 'done' - about 1 minute
as day progresses, refresh T1 10-20 ml per print (depending upon carry over)
as T2 slows, add a "splash" of T1 to bring out "color"
classic T1 = base & T2 - upper method of printing
