thin grid lines appear..
Posted: Thu Feb 21, 2019 3:41 pm
Recently I started having the following problem.
I shoot jewelry on a white foam board. After I upload the pictures to my Mac, I crop and reduce them from 5184x3888 at 300 dpi to 1500x1125 at 72 dpi. When zooming in 100%, very thin grid lines appear covering the whole image. First I thought maybe it was my Sandisk memory card which I use for at least 5 years, so I got a newer Sandisk card. But the gridlines still show. Then I thought maybe the paper of the foam board is the reason, so I photographed a white wall, cropped and resized to the same 1500x1125 at 72, still the same problem.
What could be the problem ? Thanks!
