Have you made your film holder ? Would be nice to see a photo

Is it designed for 16mm ? I presume you dunk the cylinder into the tub vertically ? Then how do you agitate the film please. Or am I completely dumb here

You want to know how I mixed each of the chemicals? Or how much flushing I did between the baths? I did a lot of flushing, filled the tank up with water and drained at least 3 times between baths. The developer, bleach, clearing bath are still very fresh. The fixer is several months old.nikonr10 wrote:To many factors at play , What did you do ?slashmaster wrote:I got my d-19!...

Give a break down of what you have done to get to this , No images on film ? too many factors .slashmaster wrote:You want to know how I mixed each of the chemicals?

That was a mistake. Why heat up the solution?slashmaster wrote:When I got my bag of d-19 I mixed half the bag in a 2 liter glass bottle. heated it up to about 115 degrees.
Oh alright. It says on both a bag of d-19 and d-76 to heat the water between 100-120 degrees for mixing. That's why I did it. Glad to know it can be done without doing that. It took a long time to mix when I did it too. I think I'm going to use a drill press with a mixing beater next time.Mmechanic wrote:That was a mistake.

Two things developing baths dislike: oxigen and warmth. The warmer the bath is the faster it oxidizes. Remember that developing baths act as reducers. There is always a REDOX double reaction, REDuction of light-struck silver salts to silver and OXidation of the agent(s). The oxidized organic compounds (hydroquinone, phenidone, and all others) turn brownish. I think you know that hue the developing bath takes on after a while. The more a developer becomes oxidized the less it will reduce. Hence, most probably, the poor result.
Best keep all baths at 20 °C (68 Fahrenheit). Dissolve at that temperature. Dissolve the dry chemicals with mechanical aid. I usually set up a wide trough, fill in the water, then pour in the powder in one continuous shot to take it under water as fast as possible, and finally rub-dissolve it with my hands in rubber gloves on itself and against the trough.
All developers contain anti-oxidizers as a protection for the reducing agent(s). Preparing my own developing baths from raw chemicals I first put in those, they bind the oxigen that’s part of the air that is always dissolved in water. We have around 8.8 mg of oxigen per liter at 20 °C. The only remedy for this problem would be to work with diver’s gear in a vacuum or a darkroom filled with nitrogen.
Always let a freshly prepared developing bath rest for at least ten minutes after the point when you don’t see any more clouding. Dissolution from grains down to molecules takes time.
After use, you can pour baths into air-tight containers, glass bottles at best.
And look where thats got the UK !Mmechanic wrote:An important saying in cinema world: stirred, not shaken.
