Summary

Description
Deutsch: Entstehung eines Fotogramms: Eine räumlich ausgedehnte Lichtquelle (1) beleuchtet Objekte (2, 3 und 9) die direkt vor dem lichtempfindlichen Film plaziert wurden. Je nach Entfernung der Objekte vom Film wird ihr Schatten härter (7) oder weicher (5) konturiert. Filmbereiche die völlig im Schatten liegen (6) werden nicht geschwärzt. Bei transparenten oder transluzenten Objekten (9) werden sie mehr oder weniger geschwärzt (8). Bereiche die voll belichtet werden (4) werden maximal geschwärzt.
English: Generation of a Photogram: A spatially extended light source (1) illuminates objects (2, 3 and 9) that are placed directly on a photosensitive surface. Depending on the object's distance to the film, the shadow looks harder (7) or softer (5). Areas of the film that are in total shadow (6) stay white; they become grey (8) if the objects are transparent or translucent (9); areas that are fully exposed to the light (4) are blackened.
Français : Création d'un photogramme : une source lumineuse (1) illumine les objets (2, 3 et 9) qui sont placés directement sur une surface photosensible. Selon la distance des objets au film, leur ombre est plus nette (7) ou plus diffuse (5). Les parties du film qui sont dans l'ombre (6) restent blanches ; elles deviennent grises (8) si les objets sont transparents ou translucides (9) ; les parties entièrement exposées (4) sont noircies.
Nederlands: chematische weergave van de belichting van een fotogram: een lichtbron (1) belicht twee voorwerpen (2, 3 en 9) die op een lichtgevoelige film zijn gelegd. Afhankelijk van de afstand tussen het voorwerp en de film is de afgrenzing tussen licht en donker scherp (7) of wazig (5). De volledig afgedekte delen van de film blijven wit (6), de volledig belichte delen van de film worden zwart (4).
