[Leica] IMG: this is VERY strange (OT)

[Peter Dzwig]

My intuition - may be wrong - that the patterns are an artefact of the Find
Edges algorithm and not due to Adobe handling the XTRANS sensor. One way to find
out more would be to changes the settings on Find Edges and/or change the
procedure that it uses in edge detection.
