FOMADON LQN 250ml – Frequently Asked Questions (FAQ)

1. What dilution ratio should I use with FOMADON LQN 250ml?

FOMADON LQN 250ml can be diluted between 1+10 to 1+14, depending on your preferred contrast and film type.

• 1+10 → Higher contrast, shorter development time
• 1+14 → Lower contrast, longer development time
  This flexibility makes it suitable for both high-speed and low-speed B&W films.

2. How many rolls of film can I develop with one 250ml bottle?

At a 1+10 dilution, a 250ml bottle can make approximately 2.7 liters of working solution, enough to develop around:

• 8 to 10 rolls of 35mm or 120 film, depending on agitation and tank size.
  Usage also varies based on your workflow and film density.

3. Is FOMADON LQN 250ml compatible with major B&W film brands?

Yes. FOMADON LQN works reliably with almost all black-and-white films, including:

• Fomapan 100/200/400
• Ilford films (HP5+, FP4+, Delta series, Kentmere)
• Kodak B&W films (Tri-X, T-Max series)
• Rollei, Arista, and other third-party films
  This makes it a universal choice for mixed-brand film shooters.

4. What development times should I expect for common films?

Development times vary by dilution and film type, but general guidelines include:

• Fomapan 100 at 1+10: ~6–8 minutes
• Ilford HP5+ at 1+10: ~8–10 minutes
• Kodak Tri-X at 1+10: ~8.5–10.5 minutes
  Always refer to the film’s data sheet or run a test roll for best accuracy.

5. Does FOMADON LQN 250ml produce fine grain results?

Yes. FOMADON LQN is formulated as a normal working, fine-grain developer.
It helps preserve image sharpness, produces smooth tonal transitions, and reduces visible grain—especially effective with films like Fomapan 100, T-Max 100, and Ilford FP4+.

6. How long does the working solution last after mixing?

Once diluted, the working solution should be used within 24 hours for best results.
Although it may last longer in airtight bottles, performance can drop due to oxidation. Fresh solution is recommended for critical or professional work.

7. What is the shelf life of the concentrated developer?

When stored unopened in a cool, dark place, the concentrate has a shelf life of 12–24 months.
After opening, it should ideally be used within 6 months.
Keeping the bottle tightly sealed and minimizing air exposure extends longevity.

8. Can I use FOMADON LQN 250ml for push or pull processing?

Yes. FOMADON LQN responds well to push and pull techniques.

• Push Processing: Extend development time to increase film speed (e.g., pushing HP5+ from ISO 400 to 800 or 1600).
• Pull Processing: Shorten development time to reduce contrast.
  This allows creative control over exposure and tonality.
