dust test -after cleaning

Still some dust on there, but not so bad.

 

I used the same curve as in the before picture to exaggerate the dust.

 

This is an out of focus shot of my lcd screen. The darkness on the left edge is probably because of the way I was holding the camera or variation in the lcd brightness exaggerated by the curve.

 

before I did the curve, it just looked all white. I curved it heavily.
