Many of the shots that have been taken with my Quicktake 200 consistantly demonstate a "halo" effect in high contrast areas. The manual, of course, does not address this issue. These pictures were taken with a tripod-mounted camera. Does anyone know of a "QuickFix' for my Quicktake, or must I resort to a Photoshop plug-in for a solution?

    Is that the same as PhotoShop calls "Posterization"? If so, it is caused by not enough color depth (i.e., you are asking it to use fewer bits to store the picture). This introduces artifacts such as posterization, because it does not have enough bits left to show different values for nearby colors.

    The quicktake was a wonderful innovation. It was ahead of its time, and never caught hold because the rest of the stuff we do today with digital photos was not there to make it really GO. By today's standards, this camera's "fine" mode would not pass muster as "extra coarse" on a more modern camera.

    Your description of that artifact reminds me of the description of "Unsharp Mask". Could the camera be pre-processing the photos to produce this effect?
