Re: Foveon
Let me summarize my argument again so there can be no straw men:
Image sensors detect colour by filtering out two channels of light from every pixel. If it's a green pixel, the filter is blocking red and blue light, sending it to /dev/null if you will. That is light that was reflected from the scene you are trying to photograph. It carries information about the scene. How could it not do? That information is absorbed in the filter and never gets to reach the image sensor. The filter is removing detail from the image, and sophisticated software is used, in post processing, to give the illusion that the detail was not removed.
Pretty easy to understand right?
It's not really possible to see the loss of detail in an image that has been scaled down anyway, which is why digital cameras these days have such high resolutions, way above the pixel count of our monitors. But what if you want to zoom to 100% of the photo and crop another smaller one out of that? Then you are missing the colour detail. Foveon is the solution today, and some other sensor will be the solution tomorrow.
This is a fantastic tool for creatives, and I'm not going to let you rain on my parade!
