I need some help with image quality. I am getting a thin shadow (usually white) surrounding images and can not find a way to adjust them out. It is like the convergence being out of calibration. I bought the camera new and have used it for about 8 months. This has been a consistent problem and seems to be worse indoors in low light. I have stopped taking any videographer projects until I can resolve the issue.

If anyone has any insight, I would appreciate any help.

Is the 'sharpening/detail' turned up too high?

Thanks, Luke, for the reply.

In the Scene menu, all level functions are set at default values of "0", Gamma is "normal" and Knee is "auto". V Detail Freq is "Thin". Progressive is "off".

Robert,

Probably sharpening. As a test, turn Detail down to off and see if you still have the problem. Probably it will be gone. If so, turn it up step by step until you are comfortable. Most people I have seen run the DVX with Detail at -3 to -7. My experience is the lower the detail level, the lower the digital look, and less noise.

Oh, and if it's not noise, could it be diffraction? Are you running at F-stops F8 and above? If so, diffraction messes up resolution and degrades the image in other ways as well.
