Digital Light & Color

At first I thought is was the particular sequence of transformations, but this happens even without performing any transformations:

Open image - one that was originally shot with a vertical camera orientation
"Save Back" (or perform a series of transformations, then Save Back...)

Image is saved in a rotated orientation, and when the embedded script is opened, an extra image has been added to a side branch:

I copied the code that handles this for TIFF files to JPEG and downloaded a suite of JPEG test files in every one of the 8 possible orientations which all seem to open OK, so the problem may be fixed in the next release.

If not, different cameras might set the orientation code differently - could you email me a sample rotated image. Also please try rotating the camera both ways (left and right) as this can generate different orientation codes as well.

The extra image is normal (see the help file).
