Perhaps i'm preaching to the converted,but since hi-res images do not show up as thumbnails,just as DNG files when looking at the files on the phone, using windows explorer,i decided to copy all the hi-res images to a new folder on the computer.On looking at the new folder in explorer, thumbnails where being shown, but with strange purple and green casts.I then decided to run all the images through Adobes DNG convertor,and lo and behold all the images where now normal,and easily viewable.
