Discussion

The (x,y) pixel coordinates of the origin point (0,0) represent the bottom row and leftmost column, respectively. Pixel (x,y) positions increase bottom-to-top, left-to-right.

If an image is encoded with this orientation, then displayed by software unaware of orientation metadata, the image appears to be rotated 90° clockwise. (That is, to present the image in its intended orientation, you must rotate 90° counter-clockwise.)
