sensor scratched?

This is my sensor cleaned (using Eclipse E2 and Swab Type 2):



I play with levels in photoshop and I see some strange lines (the white lines):



I take another shot on another white paper. The white lines disappear. Strange ? Look here:



Now what you think, something exist on first paper or sensor really scratched?

I appreciate any opinion. Thanks!

 

If the sensor was scratched, it would effect the light traveling in no matter how bright or dark or from what ever angle. I seriously your sensor is scratched, even to a small degree. Specially with the lines not showing up on the second shot.

 

Sorry but I don't understand your words: I seriously your sensor is scratched, even to a small degree.

So what this means ? my sensor is scratched? I think is not a scratch, is something on paper. I never see the white lines using a new paper and same aperture.

 

I think he meant to say NOT scratched. It would show up on all pictures, not just in special circumstances.

 

It doesn't seem scratched, but I wonder what the bright dot in the center is?

 

the bright dot appear only with 50mm lens. I see the same dot on many dust test on net.
