In this video I explore the results of developing Ilford FP4 plus at 5 different developing times, from half to twice the recommended values (3.5 min, 5 min, 7 min, 10 min, 14 min). These time variations more or less equal to a N-2, N-1, N, N+1 and N+2 development with Kodak HC-110 at 24 deg C. (Tray development with each negative shuffled once every ca. 20-30 seconds.)
The film was scanned by Epson V850 and inverted with negative lab pro leaving all settings the same for all negatives (standard inversion algorithm).
Sorry for the black hands, I have been working on my bicycle!
