FAQs
What is the shelf life of the Ilford ID11 powder?
Unopened, the powder has a long shelf life if stored correctly in a cool, dry place. Once mixed into a working solution, its shelf life is significantly reduced, typically a few weeks to a couple of months, depending on storage conditions and air exposure.
Can I dilute ID11 developer?
Yes, Ilford ID11 is commonly used at a 1:1 dilution with water (one part developer to one part water) or as a straight 1:0 solution. Dilution affects contrast and development time; always consult Ilford's technical data for recommended times.
How much film can I develop with a 5L mix?
This depends on your developing tank and reels. A standard 3-reel 35mm tank typically uses around 300-500ml of solution. A 5L mix, therefore, can develop approximately 10-16 rolls of 35mm film if using 300-350ml per roll.
Does ID11 affect film speed?
One of ID11's key benefits is its ability to retain film speed. Unlike some other fine-grain developers, it offers minimal loss of emulsion speed, allowing you to shoot at the film's rated ISO.
Is ID11 suitable for push processing?
While ID11 is primarily known for fine grain and normal processing, it can be used for slight push processing. However, other developers might be more specifically suited for significant push processing requirements.
What is the difference between ID11 and D-76?
Ilford ID11 and Kodak D-76 are very similar formulas, often considered near-equivalents. Both are classic, all-around fine-grain developers that offer a good balance of grain, speed, and sharpness. Results can vary slightly depending on the specific film used.
Troubleshooting
Uneven development or streaks on negatives
Ensure thorough agitation during development. Check that the film is properly loaded in the reel and that the developer is consistently mixed and at the correct temperature.
Grain appears coarser than expected
Verify the development time and temperature are correct for the film and dilution used. Ensure the developer solution is fresh and has not been exhausted.
Negatives seem underdeveloped (too thin)
Check that the development time is adequate. Ensure the developer concentration is correct and that the temperature is maintained throughout the process. Consider increasing agitation slightly.
Developer solution has sediment or appears cloudy
This may indicate incomplete dissolving of the powder or spoilage. It is best to discard the solution and mix a fresh batch. Always ensure water is at the correct temperature for mixing.
Pros and Cons
Pros
- Excellent fine grain characteristics for clean enlargements.
- Preserves film speed, reducing the need for exposure compensation.
- Offers a superb balance of sharpness and smooth tonal gradations.
- Versatile for use with various film types and formats.
- Ideal for achieving high magnification prints.
Cons
- Requires careful mixing to ensure consistent results.
- As a powder, it has a limited shelf life once mixed.
- May require slightly longer development times compared to some high-speed developers.
Setup, Compatibility & Care
Mixing Instructions:
- Consult the Ilford data sheet for precise mixing ratios based on your desired working solution volume (e.g., 1:1 or 1:3 dilution).
- Use distilled or filtered water at the recommended temperature (typically 20°C / 68°F) for mixing.
- Dissolve the powder completely, stirring gently to avoid excessive aeration.
- Allow the mixed solution to rest for a short period before use to ensure even temperature and chemical distribution.
Compatibility:
- Compatible with all black and white photographic films.
- Suitable for use in various processing methods, including manual tank development and large-format tray processing.
Care and Storage:
- Store the unopened powder in a cool, dry place away from direct sunlight.
- Once mixed, store the working solution in tightly sealed, light-proof bottles (ideally glass or specific plastic).
- Minimize air contact in storage bottles, using smaller bottles or marbles if necessary.
- Label all mixed solutions clearly with the date mixed and dilution.
- Discard solutions that show signs of discoloration, sediment, or a change in odor, as performance may be compromised.
