[Rollei] RODINAL



	Here's a formula for RODINAL liquid developer that I read
	in a photo newsletter years ago:
	
	RODINAL
	
	
	Distilled water        	    325 ml
	Pot. metabisulfite         5.8 gm
	
	Dissolve this completely, then add
	
	p-Aminophenol hydrochloride  25 gm 
	Pot. metabisulfite         7.8 gm
	
	When completely dissolved, add a 50% solution of
	sodium hydroxide (lithium hydroxide is the base
	in Agfa Rodinal) until a precipitate just formed
	disolves.
	
	Then, dilute to one liter. 
	
	Store the developer solution in small dark bottles.
	
	For developing film, dilute 1:20 with a 5% solution
	of sodium sulfite for 8 minute development at 20 deg. C.
	
	If sodium metabisulfite is used instead of pot.
	metabisulfite, multiply the quantity of pot.
	metabisulfite given by 0.94.
