“ensar” anastigmat optical system: 01 - positive meniscus 02 - negative meniscus
series of portraits shot with a modified ensign selfix 20 on fuji instant film.
the cameras lens consists of two elements: strong convergent lens (positive meniscus) that focuses the light and a weak divergent lens (negative meniscus) that dissipates light and accounts for chromatic aberrations.
front convergent lens that focuses the light is removed and rear divergent lens that dissipates it is left intact.
light that camera captures is the average of the subjects reflected light.
