OK gang, I am quandering this one. Any and all comments are appreciated. I have not figured this out yet. You will see a herringbone interference effect in a substantial part of the deck. It is not on the original. Nor does it show in lightroom. Only when I produce a JPG, does it show. Also I have tried changing magnification/cropping setting for the JPG, and yet it still doesn't show in Lightroom, just in the JPG, unchanged. This is a RAW file from my Fuji X-T1. They claim to have a less regimented pattern of sensor pixels, specifically to avoid having problems like this, that can show with a camera without sensor filter, and using the common Bayor pixel layout. So I am wondering if any of you have seen this specific problem? Or if you have any ideas what to do (besides re-shoot!) :-)
