Complete reversal processing kit for slide-development of 8 Fomapan 100 R 135/36 films or other B/W slide films.
Available (allow 2 weeks for delivery)
login to saveFoma's complete reversal processing kit allows for the development of eight Fomapan 100 R 135/36 films or other B/W negative films (to use as a slide film).

In this way, you get a slide with prefect grey tones.
The kit contains:
First Developer
Bleacher (potassium bichromate free)
Clearing Bath
Second developer
Fixer
Full mixing and usage instructions are included, along with a developing time table for Fomapan R. Other films can be developed by slightly varying the first developing time (5 - 11 min).

Therefore you need to mix the bleach just before you use it - preferably you should mix it during the developing process, run it through a coffee filter, and then use it. Make sure you also bleach for a sufficient length of time! We should also point out that the film gets adequate light during the second
