Adjust the chemical dilution by scrolling or entering values.
For example, for Rodinal 1+25 in 300ml set one part developer to 25 parts water.
Changing the "volume" adjusts the required volume of both water and chemicals.
Too often, I find myself
mixing cold tap water
and hot water from a kettle,
trying to eyeball the perfect 20°C.
This calculator helps you
determine the exact amounts
of each liquid needed
to reach your target temperature.
Set Temp 1 and Temp 2
to the temperatures of your two
water sources, and enter your
desired total volume.
If left unchanged,
the volume is set
to the water amount
from the developer formula.
Displays the required volumes of developer and water for the desired dilution.
Displays the required volumes of hot and cold water for the desired temperature.
Set the desired time for developing.
The timer counts down from the set time to 0 and continues beyond that into additional time.
Enter your targert temperature.
