This is precisely the case with this Vergroβerung-Aparat (enlarger) by CP Goerz Berlin. For this reason, many enlargers were developed using sunlight that we can generically call daylight. Projection means that light needs to pass through the negative and about this we have to remember that electric light, although known since 1802, only began to become available in homes in the beginning of the 20th century. The principle of every analog photographic enlarger is the projection of the image of the negative onto photographic paper. This created the need for equally practical and easy-to-use enlargers so that, starting from a small negative, it was possible to restore a size that was pleasant to look at at arm’s length. As a result, cameras have become smaller and more portable. In the 1880s, with the development of gelatine emulsion with silver halide, much more sensitive than collodion, tripodless photography, with the camera simply in the photographer’s hands, became possible. The cameras were big and heavy so that the final image could be reasonably sized. For a long time, photography used negatives that were the same size as the final copy, that is, they were not enlarged but printed by contact.
