What is the FOMA Reversal Kit?

The FOMA Reversal Kit is a chemical processing kit used for black and white slide film development. Unlike regular B/W negative film development, reversal development involves converting your film into positive transparencies (slides), suitable for projection, scanning, or direct viewing.

Each FOMA Reversal Kit contains a full set of chemicals to process 8 rolls of Fomapan 100 R 135/36 or equivalent black and white reversal films. The process includes development, bleaching, clearing, re-exposure, and final development. It’s ideal for film photographers who want to explore the slide film look with true black-and-white results.

How the FOMA Reversal Kit Works

Slide film development involves a reversal process, which differs from negative processing. Here’s a basic overview of the steps using the FOMA Reversal Kit:

1. First Developer – Creates the initial negative image

2. Bleach – Removes developed silver from the negative

3. Clearing Bath – Prepares the film for re-exposure

4. Re-exposure – Exposes undeveloped silver halides to light

5. Second Developer – Develops the new positive image

6. Final Rinse/Stabilizer – Preserves the film and image integrity

Each step is clearly explained in the included instructions. The FOMA Reversal Kit simplifies this multi-step process, making it achievable even in home darkrooms.

Compatible Films

While the kit is designed for Fomapan 100 R, it also works well with other B/W films suitable for reversal processing. Some of these include:

• Kodak Tri-X (135/36)

• Ilford FP4+ and HP5+

• ADOX Scala 160

• Rollei Retro 80s / Superpan 200

However, results may vary depending on film type and emulsion characteristics. Foma recommends using the FOMA Reversal Kit primarily with Fomapan 100 R for optimal contrast, tonal range, and sharpness.

Darkroom Setup & Tools Needed

To use the FOMA Reversal Kit, you’ll need basic darkroom gear:

• Film developing tank (like the Paterson PTP 115 Universal Tank)

• Graduated cylinders or beakers

• Thermometer

• Stopwatch or darkroom timer

• Light source for re-exposure step

• Access to water at ~20°C (68°F)
