SPECIALIST FILMS


ROLLEI ORTHO 25

Extremely high resolving power, suited for general graphic purposes. The speed is slow, around the 10 ISO mark, and contrast is high. A useful film for line copying, especially as the film is orthochromatic and can be developed by inspection under red safelighting. Using llith development at full strength will eliminate virtually all half tones, and as Kodalith is discontinued this qualifies as a close substitute. Another option is to use like discontinued Kodak Technical Pan for pictorial work, using a low contrast developer (Maco DOCUFINE) to produce an exceptionally fine grain image with high sharpness.

Characteristics;
Orthochromatic sensitised, steep grade, high speed, clear base
Extremely high resolving power, very high sharpness especially suited for the reproduction of documents, x-ray images and for producing B&W slides & blue slides for archive purposes
Suited for general graphic purposes and special effects, photographic halftone applications by use of special developers
Type of emulsion: thincoated document emulsion, traditional cubic crystal technology, steeply working
Sensitisation: orthochromatic
Granularity: RMS (x 1000): 6.0
Resolving power: 1000:1 350 lines/mm
Coating structure:
Protective coating, light sensitive emulsion, anti-halation coating (decolourised during wet processing), clear base
Thickness of emulsion: 7.5 micrometres (without base)

Ilford ORTHO COPY PLUS FILM

Behaviour like FP4 without red-sensitisation. Relatively high sensitivity for camera use, (40 ISO in tungsten, 80 ISO in daylight) and normal contrast. Available only in sheet sizes. Useful where response to red is not required, and development by inspection in red safelighting is needed. If photographing to reproduce a 'vintage' look it may be useful, as its response is closer to old blue sensitive films than modern panchromatic materials.
