Fig. 8: Light reflectance and transmittance of model high-density films before and after stimulated contamination.
From: Effect of microbial contamination of black and white photographic negative films on developed photos
Surface visible light (a) reflectance and (b) transmittance of the model high-density B&W photographic negative film samples before (labeled as blue line) and after (labeled as red line) stimulated microorganism contamination for three randomly selected spots. Surface visible light (c) reflectance and (d) transmittance of the model low-density B&W photographic negative film samples before (labeled as blue line) and after (labeled as red line) stimulated microorganism contamination for three randomly selected spots.
