The first pic had the lens cap on. Both of them had NR set to normal. At iso 6400 with the lens cap on, there was also a "red band" (not enough to bother me but it's there).
I'm just concerned because the noise/red band whatever that is shows up in the general area (bottom) at high iso + dark/black stuff.
On the 2nd pic at my first post, that is a black computer case but you can see the red noise... on the right of it is a black mesh thing it's not supposed to be red. Also, that pic was the bottom part of the full size image maybe resized a little too i forgot.
