Following Ian’s disastrous results with Fomapan and the app he used to calculate exposure, I decided to try an experiment along the same lines. I set up the camera to shoot a small white indoor rose plant using similar set up to Ian using a single energy saving light source: Shen Hao 5x4, Schneider Symmar 150mm @ f45, Fomapan 100 Exposure calculations: Indicated exposure 7 seconds. 150mm lens, 250mm total bellows extension Bellows draw chart indicated an increase in exposure of 1.47 stops so I rounded it out to 20 sec. The Reciprocity Chart for Fomapan 100 indicated the exposure needed to be increased from 20 sec to 204 sec. Developed in HC-110 Dilution F. Indicated development time was 12 minutes but having seen Ian’s results I decided to give approx. 40% less at 7 minutes. Although the flower was, as expected, still quite dense it still retained all the detail in the bloom.
