Production Grading.

1. It helps to use a different colour punched tape to identify those customer jobs that are prepared using LAD.
2. Monitor printer and process using LAD to be certain the proper densities are attained. But control printer and process independently.
3. Splice frames of LAD Control Film into each customer's original. It is best placed in the countdown leader around position 3 or 4. The first cue should be at the normal setting (i.e. 25-25-25) so the leader and LAD are printed at that setting.
4. Use the LAD printer set-ups on customer jobs as determined in the initial testing.
5. Duplicate negatives (with or without a LAD patch) are easily graded relative to the LAD Control Film using a colour analyser. A good duplicate negative should print at controls 29-29-29 (+ 5) relative to a LAD Control Film printed at controls 25-25-25.
6. Scene-to-scene grading from past jobs graded without LAD is still valid. However, a standard difference must be incorporated when printing.
