Lomography Orca 110 Developing Times?

[waynecrider]

There’s nothing on the massive developing chart for developing this film with Clayton F76. (100 iso). I’m thinking of using some other 100 iso film times unless somebody has an idea.

Control we have a problem.

Unknown film/developer combos can usually be deduced from the chart if you know a little bit about the film or developer. Clayton F76 seems to be regarded as a clone of D-76, which the dev chart lists a time of 7 minutes at 1+1 dilution for Orca 110 @ 100.

Other film entries that specify ISO 100 D-76 1+1 for 7 minutes include Potsdam Kino (also lomo), Orwo UN54+, and Shanghai GP3. With that info in hand you can probably extrapolate times for other developers, dilutions, and ISO ratings (e.g pushing Orca 110 to 400 in stock D-76 for ~10 minutes). The dev chart doesn't claim to be gospel, but should give you enough info to be confident that you'll produce printable negatives initially and can be further tuned during subsequent runs.
