El proceso inverso, dado por revelar un negativo de color con proceso E-6 genera una imagen con un colorido muy similar a las Polaroid estropeadas por el paso del tiempo. Es un recurso que ha sido utilizado con mucha frecuencia en el movimiento Lomo.<\/p>\n<p>&#160;<\/p>\n<p>El origen del invento es incierto. Algunos dicen que en una ocasi\u00f3n un encargado se equivoc\u00f3 al utilizar los l\u00edquidos en las cubetas, pero no se sabe a ciencia cierta.
