sometimes, mostly during colder conditions when I process NEF file from my camera there is output jpeg with specific pattern (enhanced to better imagination): http://www.imagebam.com/image/e9092d438689675
. I don´t know, if it is a software problem or sensor issue.
I take this photo with Tamron 17-50/ f2.8, 20s exposure, ISO 1600. For conversion I use Adobe Camera raw 9.1
Did it occur to anyone else?
