3 Marks
The marks in the margins may consist of letters, words, numbers (including frame numbering) and/or arrows, of which suggested forms are shown in Figure 1.
4 Position and orientation of the marks
The orientation specified for the marks ensures that the lettering and frame numbers read normally if included in photographic prints. When the processed film is viewed from the side opposite to the image-bearing side, the different marks shall be oriented as follows.
a) Letters, words or numbers shall appear in the correct orientation for reading, whatever the relative orientation of images and marks (see Figure 2, note 4).
b) Frame numbering
-For roll films and 126 and 135-size films, their sequence shall increase from left to right as shown in Figure 2.
-For 110-size fims, their sequence shall increase from right to left as specified in ISO 13450 and shown in Figure 3.
c) If arrows are used, there should preferably be at least one per exposure. Their direction shall be as follows.
For roll films and 126 and 135-size fims, the arrows in the margins shall point in an anticlockwise direction (also called counterclockwise) as shown in Figure 2.
For 110-size films, the arrows between the frames and above the frame numbers shall point to the left when the numbers are read normally, as shown in Figure 3.ISO 897 pdf download.
