Thank you very much for your help. As you suggested I passed my questions
and your comments on to Wolfram's technical support.

Using Reverse the image looks right but the y-axis is still wrong.  Is this
not possible without Reverse, so that both the image looks right and the
(x=0, y=0) point is in the upper left corner? Then point (x,y) on the image
corresponds to point (x,y) on the camera CCD.

In article <7es1fo$c82 at>, you write:

This one is a bit easier to answer, I think.

mainStreamListDensityPlot[data_, opts__?OptionQ] :=
  ListDensityPlot[Reverse[data], opts]

If I have somehow misunderstood your question, please let me know.
