Ethol LPD developergreenspun.com : LUSENET : Large format photography : One Thread
I've just bought several canned of Ethol LPD paper developer in powedered form. The front label says "Makes 1 gallon", however, its directions in the back label indicates "to make 25 gallons of stock solution". The net weight is 447.6 grams. I'm confused how to make the stock solution. Please help me. Thanks in advance.

Interestingly, my can of Ethol LPD says nothing about 25 gallons anywhere.
The instructions for use are as follows: Mix contents of can into 3 quarts of water at 80 - 90 F. Add cold water to make a final volume of 1 gallon. This is the stock solution, which can be used straight or diluted up to 1:4 with water. The more dilute solutions are said to give warmer tones.
I find that a 1:2 dilution gives a nice neutral tone to Ilford MG IV.

How big is your can? Let me re-phrase that. Is the container you bought about 75mm in diameter or more like 150mm? I suspect you got the large economy size. There are little cans that make a gallon of stock and I dilute this 1:3 with excellent results.
