Fomapan 100 Classic has a nominal speed rating of ISO 100, but due to its wide exposure latitude the film gives good results even when overexposed by 1 EV (exposure value) (as ISO 50/18o) or underexposed by 2 EV (as ISO 400/27o) without any change in processing.
- Black and white negative film
- ISO 100
- 35mm format
- Very fine grain
- High contour sharpness
- Wide range of halftones
1 x Fomapan 100 Classic Black & White Negative - 35mm Film, 36 Exposures, Single Roll
Fomapan 100 Classic can be processed in all common negative developers. Recommended development times are shown in the table below (the development times are related to development in a spiral developing tank - agitation or turning over continuously during the first 30 seconds, then during the first 10 seconds in every minute). In this way, medium-contrast negatives can be obtained.
When the development time has elapsed, the film is recommended to be shortly rinsed in distilled water or dipped in a 2% acetid acid solution for 10 seconds.
At a temperature ranging from 18 to 25°C for 10 minutes in any common type of an acid fixing bath, or for at least 3 minutes in Fomafix rapid fixer.
The film should be washed in running water: for 30 minutes and 15 minutes the temperature of water being below 15°C and over 15°C respectively. It is recommended to finish the processing with the film being rinsed in distilled water, or dipped in a wetting agent solution.
Unexposed films should be stored in the original packaging in a cool, dry place (temperature ranging from 5 to 25°C, relative humidity from 40 to 60 %), out of reach of harmful vapours, gases and ionizing radiations. Films stored in a refrigerator and a freezer should be acclimatized to room temperature for approx. 2 and approx. 6 hours respectively. Exposed films should be processed as soon as possible.
It is possible to process Fomapan 100 Classic also by reversal process, manually or mechanically (processor of JOBO CPA-2, etc.) for example in a "Processing set for FOMAPAN R-100“. For required transparency of the final slides the rollfilms and sheet films are the most suitable ones for this way of processing.
