SPUR UFG (Ultra Fine Grain) film is an extremely fine-grained film with variable film speed from ISO 40/17° to ISO 100/21°, pushable to ISO 160/23° with the new SPUR UFG-1 developer.
The spectral sensitization goes far into the red range and allows the film to be used with an infrared filter (715nm recommended).
The maximum resolution of the film material is 287 LP/mm at a contrast of 1000:1 and 101 LP/mm at a contrast of 1.6:1 when developed with a high-contrast developer for aerial photography.
Due to the very fine grain, very high sharpness cannot be achieved with conventional developers, and the characteristic curve also leaves a lot to be desired when conventional developers are used. This is because the film was originally developed for aerial photogrammetry rather than image-wise purposes.
For this reason, SPUR has "tailored" a special developer for this film, which completely eliminates the above-mentioned problems. With the new two-component developer SPUR UFG1, high sharpness and high resolution are achieved while maintaining the extreme fine grain, and in addition
the characteristic curve is corrected and improved.
Contains 2x SPUR UFG 120 films, SPUR UFG developer 50ml part A, 50ml part B
