Now that is an odd reply Mr Chip because one sensor will only record a
single grey level so if a one sensor chip existed one must assume that the
image would appear as a single tone grey object.

In addition as one is led to believe that three sensors sit side by side on
a CCD or CMOS device in order to record the appropriate primary colour
responses, then a single sensor would be quite unable to do this.

Come sir lets have some sense here.
If it requires three adjacent pixels to capture a colour combination then
the usable resolution on a 6Mb chip is 2 Mp for any  of the three primaries.
In that case the total recordable subject  information must be limited by
the available number of  pixels for any given unit area of a particular
image. This must indicate, using any form of logic you care to apply, that
the more sensors available for any given unit of image area, the better the
rendition of any particular area of image detail - all other relevant
factors being equal, which in the case of the Canon 10D and 1Ds will surely
be so.

The question of the particular dynamic range and illumination sensitivity
for any given "other cameras" chip are entirely separate issues and one
would assume that on the two cameras listed they are virtually identical and
so I would submit that my original observation that the 10D was capable of
resolving a greater level of image data than the 1Ds for any comparative
compositional area of subject matter still stands.

Now then, if someone on here has both models, perhaps they might consider
testing this assumption and make the files available to any interested
parties. This would at least offer a more objective piece of evidence than
mere individual expressions of opinion.
