For David Millier

About the advantages of the layered design approach.

The one that most interests me most is it gets rid of the CFA and need for mosacing, which cuts the blur and artefacting this provides. Of course, soon as we also dispense with the AA filter, we introduce another set of artefacts to replace the demosaic flaws. Most people around here don't seem to care about aliasing artefacts (in fact they like them), and believe that getting rid of the AA filter is a step foward. There are quite a few vocal reviewers supporting this line too. Manufacturers seem more reluctant.

But did Foveon speak about this at all at the beginning (before Sigma)?  It would be interesting to know their thinking on why the layered solution was such a good one. There's plenty of Foveon history students around here, does anyone know what Foveon said (not in marketing material but in enginnering literature)?
