| Landscape Photography IMPROVED RENDERING OF CLOUDS AND COLOUR BRIGHTNESS Photographed on non-colour-sensitive material. Photographed on Pan-chromatic material with a Delta Filter (Ilford Filter No. 209). 30 Fig. 13. This page from 'Pan-chromation', containing half-tone blocks and printed matter, was copied on an Ilford Special Rapid Plate. The exposure used for the copy negative was kept to the minimum by using the shadow method. The 'spot' was matched on the darkest part of the illustration. Daylight illumination was used, care being taken to avoid reflections. The exposure was 10 seconds at f/11 (see page 19). 31 | ||
