3. High Volume (1+7)
   Save developer and life—Ilfotec DD-X still delivers reasonable results with careful temperature control.
4. Temperature Control
   Maintain 20 °C (68 °F) during processing for consistent results with Ilford Ilfotec DD-X.
5. Agitation
   Gentle continuous or intermittent (inverted) agitation works well with this developer, depending on desired contrast.

 Developer Comparison

• Overdevelopment: Slightly reduce time or dilute further.
• Flat Negatives: Increase dilution strength or raise development temperature.
• Uneven Development: Ensure accurate temperature control when using Ilford Ilfotec DD-X.
• Exhaustion/Tired Developer: Replenish 10–20% between batches if using heavily.

 Best Practices for Long-Term Use

• Label your Ilford Ilfotec DD-X bottle with opening date.

Frequently Asked Questions – Ilford Ilfotec DD-X Developer

1. What films work best with Ilford Ilfotec DD-X?

Ilford Ilfotec DD-X works exceptionally well with ISO 100–400 B&W films, including Ilford HP5+, FP4+, Delta series, Kodak Tri-X, and most modern emulsions. It’s ideal when you want fine grain and rich tonality.

2. What is the recommended dilution ratio for everyday processing?

The standard dilution is 1+1 (one part DD-X + one part water). This gives balanced sharpness, contrast, and grain—perfect for most films and shooting conditions.

3. How long does Ilford Ilfotec DD-X last after opening?

Once opened, the concentrate typically stays usable for up to 6 months if stored properly in a cool, dark place. Mixed working solution should be used immediately for best results.

4. Can Ilfotec DD-X be reused?

DD-X is generally designed for one-shot use, meaning it’s used once and discarded. However, with careful replenishment (10–20%), it can handle small batches, but results may vary.

5. What temperature should I use for development?

Maintain 20°C (68°F) for consistent results. DD-X performs reliably between 18°C and 24°C, but staying near 20°C ensures accurate contrast and shadow detail.

6. Does Ilfotec DD-X reduce grain?

Yes. One of DD-X’s strengths is producing very fine grain, especially with medium-speed films like FP4+ or Delta 100. Even higher ISO films show smoother grain compared to many other developers.

7. Is DD-X suitable for push processing?

Absolutely. Ilfotec DD-X handles push processing very well—especially with HP5+ and Delta 400—maintaining good shadow detail and moderate grain, even at +1 or +2 stops.

8. How does DD-X compare to Rodinal or Kodak D-76?

• DD-X = fine grain, rich tones, convenient liquid form
• Rodinal = high acutance but more visible grain
• D-76 = general-purpose, moderate grain
  If you want professional, smooth, high-detail negatives, DD-X is often the superior choice.
