Very annoying Vertical lines

What are these faint vertical lines??

Supposedly taken by 645D. Interesting to say the least. Pretty annoying too.

I see the lines.
That's not a photo directly from the camera, it's been severely messed with in post.

Really? I see about five of them. The distance between the two is about the width of a car. I have looked at several monitors and I see them. Should I print it???

Steve, why post processing make them appear?

Have you tried using another memory card?

I can see them too, but they can be accentuated by using the clarity slider in LR or structure in Nik Efex or similar.

I printed it - it is hideous and pitiful. Not cool.

It's possibly the result of jpeg compression of the large, relatively monotone area.

This may have to do with the sensor, I get a faint line when I shoot at higher ISOs, usually it's directly in the center of the frame...I believe this has been called a split sensor issue that is common with the 645D. You may be able to remove it from future images by running a "pixel mapping" (or called something close to that), which I know gets rid of 'stuck' pixels and sometimes removes the lines. My understanding is that this can come from the fact that the 33x44 sensor is actually two sensors put together. I believe they do the same thing with FF 35mm sensors as well, though I'm unaware of any with that issue.

After looking at the actual image I'm not sure what that's from...seems the image was heavily processed and I think that may have played a factor.

That one's a head-scratcher. It certainly has been majorly processed.
I see that some of the other pics from the set have very strong processing as well: https://www.flickr.com/photos/nubimd/8972914991/in/photostream/
