the characters of original Aufi are well suited for reproduction Enlargements.

When producing larger, this process offers the advantage Simplicity, because you need ζ for each C instead of the previously required ζ.

Carry out the procedure in the following way:

It is initially based on: group respectively. Individual or objects a negative angel this is produced in a known manner, d. H. a glass plate, Figures and which together with these contains the foreground covered in opaque, but otherwise ν is sight.

and used in the particular landscape in such a way that it precedes the photosensitive plate is turned on. In this way you get a landscape negative, which would contain the figure silhouette if it were to develop. The record is still going to be released at this stage not developed, rather exposed again, in contact printing with an upstream connection a slide of the figures and the foreground, in which all other places, i.e. those that were left transparent with the silhouette plate, with more opaque Color are covered. This second exposure does not change the background of the landscape plate, but it does a negative of the figures is created in the space that has been left out until now. The plate represents then, after development and fixation, a complete combination negative represents used for enlargements and reductions or for the production of positive copies can be.

If it is to be combined with an already existing landscape photograph, then of the landscape negative concerned first Slide produced; from this one then receives the combined one in the reproduction camera using the same instructions Negative.

If you want to make slides using this method, you first make a landscape negative at. From this one takes a landscape positive in the reproduction camera with the interposition of the silhouette plate and exposed before development

sometimes with a figure negative, the background of which is covered light-tight.

Claims (1)

Patent claim: Process for the production of combination recordings, characterized in that at the inclusion of the background a silhouette of the foreground immediately in front of the sensitive one Plate switched on and, before developing, a plate representing the foreground with a light-tight covered background copied by contact printing on the same sensitive plate.
