Description
Used in IFD 0 of DNG files.
Specifies the encoding of any depth data in the file. Valid values are:
0 = Unknown: The exact mapping of distance values to depth map is unknown, other than nearer distances are closer to zero, and farther distances are closer to the maximum value.
1 = Linear: The depth values vary linearly, with zero representing the "near" distance (see the DepthNear tag) and the maximum value representing the "far" distance (see the DepthFar tag).
2 = Inverse: The depth values are stored inverse linearly, with zero representing the "near" distance (see the DepthNear tag) and the maximum value representing the "far" distance (see the
DepthFar tag).
