Abstract: THIS PAPER explains the technical reasons behind the picture-design adopted for the BKSTS reference leader picture, intended to assist the objective and subjective colour balance control of 16 mm and 35 mm prints in both the film laboratory and the television studio. Four frames of the standard negative are inserted in the leader at the colour reference position of each cut negative roll and the whole roll is then graded to look consistent with the leader picture. The leader picture later helps the telecine operator to adjust the colour balance of his machine. The original test scene was constructed of specified materials and special care was taken to ensure that the 16 mm version had a grey area big enough for easy routine densitometry. Both 16 mm and 35 mm negatives are available as the BKSTS Girl No. 1 (5254) and BKSTS Girl No. 2 (7254), and prints are available graded to Status A neutrality on the Control Square.
