I’m developing Arista EDU Ultra 200 black-and-white film in F76+ and exposing the film at EI 200. The Massive Dev Chart doesn’t list this exact film/developer combination. What time and dilution should I start with?

Fortunately, Arista .EDU Ultra films are rebranded Fomapan (based on everything I've been able to find relative to times, grain structure analysis, antihalation dye characteristics, and cost).

You should therefore be able to use this page to find times for your .EDU Ultra 200 by using the times listed for Fomapan Creative 200.

Generated from our catalog & community — verify before relying on it.

A practical starting point is F76+ diluted 1:9 for 7 minutes 30 seconds at 20°C (68°F) for Arista EDU Ultra 200 rated at EI 200.

Community experience also notes that Arista EDU Ultra films are widely regarded as rebranded Fomapan, so if you need a cross-reference, you can look at Fomapan 200 / Fomapan Creative 200 times for guidance.

As with any film/developer combination not officially listed, treat this as a starting point and adjust slightly for your process, agitation, and desired contrast after evaluating your negatives.
