No more re-washing

Before using this, I often had to re-wash films due to spotting. Now, one dip and hang dry is all it takes. It saves so much time in the darkroom.

Professional results at home

As someone who develops film weekly, this is a staple in my chemistry lineup. It makes the difference between amateur and professional-looking scans.

Good product, mild odor

Very effective at preventing drops. The only minor downside is a slight chemical smell, but it dissipates quickly once the film is dry. Overall very satisfied.

Saved my archival project

Processing a large batch of historical rolls, and consistency is key. FOTONAL ensured uniform drying without any marks. Highly recommended for serious photographers.

Essential for spot-free negatives

I used to struggle with hard water spots ruining my scans. This solution completely eliminated the issue. My negatives come out perfectly clean every time.

Works well but requires careful dilution

The product does exactly what it promises. Just make sure to follow the dilution ratios strictly, or you might get residue. Great value for the volume.

5 FAQ

Q: Does this solution affect the archival quality of the film?

A: No, FOTONAL is pH neutral and leaves no residue that would degrade the emulsion over time. It is safe for long-term archival storage.

Q: What is the recommended dilution ratio for standard tap water?

A: For most tap water conditions, we recommend a 1:200 dilution ratio (5ml of solution per 1 liter of water). Adjust slightly for extremely hard water.

Q: Is the bottle made from recyclable materials?

A: Yes, the bottle is made from HDPE plastic which is widely recyclable. Please check your local recycling guidelines for proper disposal.

Q: Can this be used with color negative film as well?

A: This specific formula is optimized for Black & White film. While it may work on color film, we recommend using our Color Safe variant for best results on C-41 processes.

Q: How long should I leave the film in the solution before hanging to dry?

A: A quick immersion of 30 to 60 seconds is sufficient. Gently agitate the tank or container during this time to ensure even coverage.
