Hi Mike,

The issue with color "accuracy," as you say, is primarily one of post capture processing, however, no amount of post processing can retrieve subtle variations of hue which were not captured in the first place.

No Bob,

This is exactly the problem with the CFA sensor. If subtle variations of color are not captured - and they are often not captured with CFA sensors, then they can't be reproduced in the finished image or print.

The facts are the facts. Your subjective preference is your preference. There is nothing wrong at all with you preferring the Foveon's colour response, but it is simply not as accurate as the organic colour filter. You should be able to express your preference without needing to bend fact to make your preference somehow 'factual'.\

No Bob,

What you present as "facts" are not facts at all. They are "your" suppositions based on what you have read. When theory and practice collide and practical experience doesn't match theory, then practical experience trumps theory. This is true in science or in the real world.

We tire here of having to constantly explain to non-Sigma users who visit this forum what everyone here already knows. If you hang around long enough, you "may" learn a few more things which you "thought" you already knew, but are quite mistaken about.

The topic of the thread is what are the advantages of the Foveon filter - now one can take that in an objective way or a subjective way. Your way is to say 'it's better because I like it', nothing wrong with that, but the objective facts remain the facts.

I and other forum members here have neither the time nor the inclination to educate every visitor who comes here to "straighten us out" about Foveon technology.

Then don't do it.

You may "think" that you are correct because you have read "all about it" elsewhere. Until you actually "use" the cameras and put in the necessary time and effort to truly know what you are talking about, you are simply an irritation wasting our bandwidth with arguments which have already been discussed ad nauseum.

All I have done is put across what is the actuality - you seem to wish to create a fantasy of your own to support your preference. There is no need, your preference is valid for you just because it is your preference - but it isn't valid for everyone else. I haven't said anything derogatory about your choice or Sigma cameras, simply what is the fact of the matter about the performance of Foveon sensors.

No Bob, What you have done is present what you "think" is actuality. It's not me who is creating a fantasy. I "know" what I get from my very large collection of both Sigma and pro-level CFA cameras. You present yourself as an "expert" on Foveon sensors, yet you have yet to demonstrate that you know anything at all about them except what you have read which fits your own quite obvious bias. You are sounding very much like a Joe W. "mini-me" here.

I have told you that CFA sensors have very poor color resolution. It has been demonstrated  "scientifically" by color resolution chart photography multiple times and right here on dPReview. If the sensor can't "resolve" the colors, all the "organic" filtering it the world can't produce the colors. Interpolating colors simply is not as accurate as primary detection of colors. Now you keep right on arguing and presenting your irrelevant "data" and you go right on believing what you wish to believe. But "please" stop trying to tell people who actually "use" this technology that they are blind and incompetent.
