Gregor, you see, that "rings caused in the image by digital cameras"
will be on-topic for quite a while.

Be assured that I fully dis(!)agree with you. Otherwise I would not
have been crazy enough to spend so much effort on this matter. There
are so many disappointed coolpix-users! During my investigations I
learned to know many micro-photographers, amateurs and profs, who
never had read or posted in newsgroups in the usenet, or in
web-forums, thus the artifacts problem is totally under-estimated in
the NG, and especially by happy persons using a Cp 990 barely showing
the artifacts. In my report I clearly pointed out, that many Cp 990
are not concerned. Therefore it would be methodically incorrect to
judge this problem by taking a few happy 990-users for a basis. A lot
of microscopists using a digital zoom-camera cannot afford to put
their camera away, and buy another one, and another one ... They try
to find out, what causes those da ... circles, and they are glad of
any hints for their understanding of what happens in their camera.

Sic!
