So, I shot and develop a roll of 35mm Fomapan 400 with Rodinal following the data in digitaltrhth.com.
But later on I founded out the real ISO of fomapan 400 is 250 with Rodinal.
So I wonder of the data in digitaltruth.com, dispite it says ISO 400, is indicating the development time for its real ISO which is 250?

I god a good result from development but I usually over expose a bit.
