ABSTRACT:
An exposed and developed filmstrip and band of similar length are connected edge-to-edge. An address for each negative of the filmstrip is imprinted on the band in the form of a bar code adjacent to the respective negative. The negatives are scanned and exposure values are calculated for the negatives from the resulting data. The exposure values are used to make proofs, and the exposure values for each negative are then stored in a memory under the corresponding address. When an order for final copies of a particular negative is subsequently received, the address of the negative is read from the band and used to retrieve the respective exposure values from the memory. The final copies are thereupon made based upon the retrieved exposure values.
