Photographic enlarger for use in bright light

Abstract

A photographic enlarger for use in bright light comprises a light-tight space which is enclosed in a casing, a bellows and a box thereon; the box is displaceably mounted on the casing for upward and downward adjustment and contains a light source emanating projecting light, a transparency holder, an enlarging objective and a deflecting mirror. On the floor of the casing a carrier block, which is displaceable freely on the floor in any direction, carries a lenticulated reflecting screen and a hingedly connected masking frame. A light-tightly closable window is provided in the box and permits viewing through the same, when open, the entirety of the surface of the lenticulated screen via the said deflecting mirror. In the front wall of the casing, two handholes having light-tight covering means are provided which allow for manipulation of the carrier block and of the masking frame and also render it possible to switch the light source on and off by means of a light switch inside the casing. Focussing can be carried out when the window is open, via the deflecting mirror by observing the very bright enlarged image of the transparency on the lenticulated screen. Inside the casing, a sheet of unexposed photographic paper can be taken out of a light-tight envelope and can be placed on the screen, exposed thereon and then returned again to the light-tight envelope.
