Ilford ILFOTEC DDX Developer - 1L

The most common dilution for one-shot use is 1:4 (one part DD-X concentrate to four parts water). For economy, it can be reused, but image quality might be slightly reduced.

No, Ilford ILFOTEC DD-X is specifically a black and white film developer and should only be used with black and white photographic films.

The standard development temperature for ILFOTEC DD-X is 20°C (68°F). Always use a thermometer to ensure accurate temperature control.

Diluted developer is best used immediately. If stored, use within 24 hours, but be aware that its performance may be slightly diminished. Concentrated DD-X should be stored tightly sealed in a cool, dark place.

Yes, DD-X is well-suited for push processing and can help maintain good shadow detail and tonal range even when film speed is increased.

This depends on the dilution and tank size. For a 1:4 dilution and using a standard 35mm Paterson tank (requiring approximately 300-350ml of diluted developer per roll), a 1-liter bottle of concentrate can develop roughly 7-8 rolls of 35mm film.

Yes, ILFOTEC DD-X can be reused, especially in larger volumes like deep tanks. However, each subsequent use will slightly reduce its activity, potentially requiring adjustments to development time. For critical work, one-shot use is recommended.

Ensure the developer was mixed at the correct dilution and temperature. Verify that the development time was adequate for the film and dilution used. Check that the developer was fresh and not expired.

While DD-X is a fine-grain developer, very aggressive agitation or overdevelopment can increase grain. Ensure proper agitation technique and development time. Consider using a finer-grain film if grain is still an issue.

This is often caused by insufficient agitation or poor mixing of the developer. Ensure consistent and adequate agitation throughout the development process. Double-check that the developer was thoroughly mixed before use.

Wear protective gloves and use a chemical-resistant apron when handling photographic chemicals. Clean up any spills immediately with water.
