When you dissolve a solid in water the volume usually increases. So to avoid having more volume than anticipated you start with less water, dissolve the solid and make the volume up to the specifieded volume. Interestingly this does not work with liquids. Mix a liter of water and a liter of ethyl alcohol and you get less than 2 liters of mixture.
Yessir. Mix a liter of water with 1 liter of any sort of alcohol and you get most of time 1 liter of water. Why spoil a good whiskey with water ?
I never bother with precise 1 liter barrier with 0.001 % precision. For fixing and bleach solution is waste of time, after first roll of film the solution is like a dilute solution until you add refresher and even after that the solution is far away than ideal.
For developer is the same. I don' t think that more 10ml of water will spoil the solution. After years of practice anybody can put precise amount of water from start.
Ok. the developer need more attention but i find is not so critical. More critical is exposure time and for slides that is crucial.
I remember from my highschool time I had extremely underexposed negatives and I processed the paper with an extreme procedure like hot concentrate developer ~50°C and working time just enough to pass paper into solution.. around 0.5 seconds.
Did you think precise 1liter dosage will help ? 1 liter dosage is for reproductibility not for art.
