Spur-Orthopan UR

A few days ago I loaded my M-A with Spur Orthopan UR film. It should be known that this is an Agfa-Gevaert microfilm emulsion with a useable sensitive for photographic purposes from ISO 6 to ISO 25. When using the Apo-Summicron-M 2/50 mm ASPH. the shutter speed is between 1/125 and 1/500 at f/2 or f/2.8 depending on the brightness level of the ambient light. For these pictures, made in sunny bright daylight I selected ISO 6. The negatives had a high contrast, but showed no grain at all. The scanning procedure did not reduce the contrast. The two pictures below show that this emulsion is capable of producing images that are equal to what is possible with computational photography. isabelle-01_copya53_copy
