Recommendations

For optimal results, use ID-11 at 20°C (68°F) and follow Ilford's recommended development times. For fine grain with normal contrast, use stock solution. For increased sharpness and slightly higher contrast, dilute 1+1. For maximum sharpness and reduced grain, dilute 1+3 (one-shot only). Always store mixed solutions in full, airtight bottles away from light.
