NOTES:

When using these films, use STANDARD concentrate diluted 2:8 at 24°C / 75°F.

∗∗ When using these films, agitate continuously for the first 15 seconds, then one inversion each minute thereafter.

CHART LETTERS:

If your desired working temperature does not appear on this chart, you may use Sprint’s Chart Letter System to determine development time for your film. To use this system, make note of and click on the “Chart Letter” listed next to your desired film.
Once noted, this letter can be used to find a development time on our Development Timing System Chart.
This chart can also be used in conjunction with our recommended CHART LETTER ADJUSTMENTS to determine the appropriate adjustments for changes in working solution temperature, variations in film exposure and a variety of other processing conditions.

Note: All adjustments are in letters. For example, a Chart Letter of “Q” with an adjustment of +2 for a plastic lens would yield a final Chart Letter of “S”

Once you have determined the appropriate Chart Letter, with adjustmens, click here to view our Development Timing System Chart.

ADDITIONAL NOTES:

This chart is based on developing activity which doubles per each increase of 6.6°C / 12°F. Most black & white films should remain below 25°C / 77°F.

These processing times have been optimized to produce negatives for printing with a condenser enlarger on variable contrast paper with a 2 1/2 filter.
