By popular request by the infamous Phil Bond of Phil Bond Photography , here's a chart for Fomapan 100. I'll post the 200 Fomapan chart in a separate chart. But first a few words of caution. This is data I've found and not tested. In this case, the reciprocity corrections come from an Android reciprocity exposure correction app. And that app acknowledges Foma only publishes corrections up to 100 seconds, so the author extrapolated. Also I did all the calculations by hand and could have screwed up. Another word of caution, films with very poor reciprocity characteristics are subject to another problem: high contrast. That having been said, here's the chart.
