volume of developer for Unicolor drum method

[Philippe Gauthier]

I'd way that 300 ml is way too much - but it could depend on your developper. I actually only use 110 to 125 ml (less than 4 ounces) of chemical in a 8x10 drum loaded with two 4x5 sheets. I use HC-110, dilution B. Never had any problem, even with short (4 min) processing times.

I agree. I used 4 ounces to process three negatives a couple of days ago. They came out fine.

Why waste so much developer?

aside from the minimum ammount of liquid the tank actually needs to work effectively, if you are being over generous with Ilford's figures (or using 1:9 dilution), you only need 50ml per 4x5 sheet.

If you follow Ilford's averaging figures, you actually only need 25ml of DD-X 1:4 per sheet of 4x5
