Fomadon LQR developing times vary by film, but for Fomapan films at 20°C (68°F) and 1+10 dilution, expect around 5-6 mins for Fomapan 100, 5-6 mins for Fomapan 200, and 7-8 mins for Fomapan 400, with adjustments needed for different film speeds or if you want higher contrast (shorter time) or more detail (longer time). Always check a Massive Dev Chart or the Foma website for specific film/developer combinations.
General Times (at 20°C / 1+10 dilution):
- Fomapan 100: 5-6 minutes
- Fomapan 200: 5-6 minutes
- Fomapan 400: 7-8 minutes
Key Factors & Tips:
- Dilution: LQR is often used at 1+10, but times change with dilution (e.g., 1+25).
- Temperature: 20°C (68°F) is standard; warmer temps speed development, cooler temps slow it.
- Agitation: Continuous for the first 30 seconds, then 10 seconds every minute (for tank development).
- Contrast: Shorter times (e.g., 5 mins for Fomapan 100) give higher contrast; longer times (e.g., 6 mins) can retain more highlight detail.
