Technical Information |
All photographs were taken with 35mm SLR cameras and
with manual focusing single lenses from 18 to 300
mm including two macrophoto lenses. Film was Agfa Scala slide material (see Agfa Scala datasheet). This is a black and white slide film with a nominal speed of ISO 200/24° (the new version 200x may be pushed or pulled). Scala requires a special development process. The slides tend to show just a hint of sepia tone which is difficult to reproduce on Ilfochrome as well as in digital imaging but which gives beautiful results in projection. With Scala it is possible to control contrasts by using standard filters. For general outdoor use I recommend Wratten #11 (yellow-green) while Wratten #22 to #29 (orange to dark red) are useful to heighten contrasts dramatically. Also try #38 (blue), especially in foggy weather. When using an external light meter (I usually get perfect results with an incident light meter while for critical high-contrast shots I refer to additional spot metering), just compensate as recommended on the filter. For Wratten #11, compensation should be about +1 f-stop, for #38 about +1,5, for orange and red filters between +1,5 and +3 f-stops, depending on intensity of the filter. When you use an orange or red filter together with TTL metering, you should expose about half a step longer than indicated by the camera. That's because the film emulsion seems to be slightly less sensitive to red light than an exposure meter. |
