minimum HC110 per roll

[darkprints]

Is there a definitive consensus on the minimum amount of HC110 syrup needed per roll - 3 ml. or 6 ml.?

By roll, I mean 80 sq. in., or 135-36, or 120.

 

And does anyone have first hand experience finding that 3 ml. is not enough?

 

I can't recall why the recommended amount changed from 3 to 6 ml.

Here is a great thread that discusses HC-110. Of course amount would vary according to total

 

I use 7.5/232.5 = 240 (8 oz.) with good results.

The smallest amount of concentrate that Kodak lists on their HC-110 tech publication is 9mL (for dilution B to make 300mL of liquid), so that would imply that they believe you need at least 9mL. I don't personally use HC-100, so I can't speak from personal experience. Probably the only way for you to be sure is for you to shoot test rolls and try it.

Covington Innovations recommends a minimum of 6 mL per 135-36 roll.

 

I have personally used 4.5 mL on a 135-36 roll at dilution H and it turned out OK.

Like Evan, I have 4.5 ml consistently for years with dil H. Sorry, I don't know about 3 ml.

If there is not enough developer then the devoloper will tend to poop out during the development; some folks actually experiment with this.

Dilution H (1:63) calls for 4 ml. per 8 oz. (250 ml.)

 

Covington had originally stated 3 ml. per roll, then without explanation changed it to 6 ml.

I'm wondering if there was a reason for the change.

I use 9.5ml for 1 roll but in 600ml solution (Dilution H) for "1" roll in a 2 roll tank. Solves the solution poop out problem.
