Table 1 Optical density (OD) of model high- and low-density B&W photographic negative films before and after stimulated microorganism contamination
From: Effect of microbial contamination of black and white photographic negative films on developed photos
Samples | OD | T (%) | ΔT(%) | |
|---|---|---|---|---|
Model high-density samples | Before simulated microorganism contamination | 2.42 ± 0.03 | 0.38 ± 0.13 | −0.33 |
Treated with simulated microorganism contamination | 2.15 ± 0.02 | 0.71 ± 0.21 | ||
Model low-density samples | Before simulated microorganism contamination | 0.15 ± 0.01 | 70.79 ± 0.65 | −18.34 |
Treated with simulated microorganism contamination | 0.05 ± 0.01 | 89.13 ± 0.58 | ||
