The point is, if DP uses ShiftN to correct perspective, and since ShiftN does retain EXIF info after perspective correction, so DP could also retain EXIF instead of strip it out.
I understand it is a new image in DP, but processing the image in ShiftN also generates a new image, retaining EXIF.
Does it make sense to suggest Xara to fix this behavior, in order to incorporate/match better ShiftN output, which retains EXIF?
