To mix, add 1 part Solution A , 1 part Solution B and 10 parts water for normal film.

Developing times:

ISO 25-50 films - develop for 6 minutes @ 70 degrees F.

ISO 64-125 films - develop for 8 minutes @ 70 degrees F.

ISO 400 films - develop for 10 minutes @ 70 degrees F.

For Imagelink FS microfilm exposed at ISO 100, - 1:1:60 dilution, develop for 8 minutes @68 degrees F.
