Abstract
A film matrix is reproduced and altered by mounting a replacing image on a light transparent sheet over the image to be replaced on the film matrix. The image to be replaced is obliterated. The mounted replacing image and the film matrix are then double exposed on another piece of film to produce another film matrix with the replacing image appropriately inserted.
Claims5
A method for altering an image including one or more characters located anywhere on a first negative film matrix, under controlled conditions, comprising the steps of:
- a. exposing the first negative film matrix on film to produce a first positive film matrix which is an exact duplicate;
- b. exposing the first positive film matrix on film to produce a second negative film matrix;
- c. overlaying a grid on the first positive film matrix;
- d. overlaying a light transparent sheet over said grid;
- e. positioning and mounting a replacing image on the light transparent sheet within the desired cell of said grid over the image to be replaced;
- f. exposing the mounted replacing image on film to produce a third negative film matrix;
- g. covering the image to be replaced on the second negative film matrix with a photographically opaque substance;
- h. double exposing both the second and third negative film matrices on the same film to produce a second positive film matrix;
- i. exposing the second positive film matrix to produce a fourth negative film matrix which has the replacing image in the position of the replaced image.
A method for reproducing and altering a first film matrix having images including one or more characters located anywhere thereon, comprising the steps of:
- a. mounting said first film matrix on a jig;
- b. mounting a positioning guide having cells of the approximate size of a single character on said jig over said first film matrix;
- c. mounting a light transparent sheet on said jig over said positioning;
- d. aligning a replacing image within one or more cells of said positioning guide in the desired location over said first film matrix and fixing said replacing image to said light transparent sheet;
- and
- e. double exposing said replacing image and said first film matrix on film to produce a film matrix which includes said replacing image inserted precisely in the desired location with respect to the other images on said first film matrix.
