 +> Hi Federico,
 +> I'll brake a pledge of OMETRA and tell you a secret given by American war photographers to Russian war photographers at the end of World War II.
 +> HOW TO FIND OUT PROCESSING TIME OF ANY FILM IN ANY DEVELOPER:
 +> 1. In a darkroom cut off a few strips 6-8 mm wide from the film you want to develop.
 +> 2. Turn the lights on. The strips are fogged now.
 +> 3. Take one strip with your right hand and a stopwatch with your left hand.
 +> 4. Dip one half of the strip in a developer and start a stop watch. The emulsion side of the
 +> film strip placed in a developer will start lightening first and then darkening.
 +> 5. WHEN THE DARKNESS OF BOTH PARTS OF THE STRIP MATCH STOP THE STOPWATCH!
 +> 6. Divide the number of SECONDS shown by the stopwatch by 3. This is your developing
 +> time in MINUTES. If stopwatch shows 24 seconds, developing time is 8 minutes.
 +> 7. Repeat two-three times for consistency. This method never failed for the last 60 years.
 +> Buena fortuna,
 +> Victor Petryakov
