The following data are a summary of a brochure I obtained from
Acufine, Inc. The data are reproduced here as a help to other
photograhers; I assume no liability for transcription errors. I have
generally found these data to be quite reliable. The data refer to
the following conditions:
- Condensor enlarger.
- Agitation: 5 secs every 30 secs.
- Capacity without replenishment: 16 rolls (120 or 135-36)/quart.
- Compensation: Add 2% for each roll after the 4th.
- The two rightmost columns are for "emergency situations" only.
I have omitted the information about some old films that are no longer
available.
